Introduction

After the brain, the heart is regarded as the second-most significant organ. Every heart disruption causes the entire body to become upset. Heart disease is one of the top five killer diseases in the world. Disorders, including heart disease, are a result of the changes that occur to us daily. Consequently, it is crucial to predict a sickness at the appropriate time. Data mining is a fundamental and fundamental process for defining and discovering relevant data and uncovering hidden patterns in massive databases. By predicting and diagnosing various diseases, data mining, and machine learning techniques are used in the medical sciences to address genuine health-related challenges. This study compares the performance of three machine learning algorithms-support vector machine, decision tree, and random forest-for the prediction of heart disease.

Machine Learning-Based Approach for Diagnosing Cardiac Disease

The study emphasizes the critical need for swift and accurate heart disease identification, proposing a machine learning approach with Support Vector Machines, Logistic Regression, Artificial Neural Networks, K-Nearest Neighbors, Naive Bayes, and Decision Trees for classification. Efficiency is enhanced through feature selection algorithms and a conditional mutual information method, ensuring commendable accuracy, particularly with Support Vector Machines. This makes it a promising tool for rapid implementation in medical settings, crucial for early identification and interrupting cardiac disease progression. The analysis of diverse datasets identifies key features for heart disease prediction, utilizing seven machine learning methods. A hybrid dataset is created and analyzed with Python's Scikit-learn module using a univariate feature selection technique, offering a comprehensive approach to discern crucial factors in predicting and preventing heart disease.

Provides the Maximum Accuracy, Several Parameters Relating to Various Algorithms:

Datasets are split into training and testing using holdout and cross-validation techniques, adjusting algorithm parameters for maximum accuracy. Evaluation metrics, including a classification report and confusion matrix, gauge performance. Majority voting, combining logistic regression, SVM, and naive Bayes, achieves 88.89% accuracy on the first dataset, while the hybrid dataset lags individual ones. Project outcomes are compared with prior methodologies. Machine learning, an algorithmic system falling under AI, learns without explicit programming, relying on statistics and data for outcome prediction. Linked to data mining and Bayesian modeling, it operates by taking data as input and generating answers through algorithms, seen in applications like personalized recommendations, fraud detection, and predictive maintenance.

Machine Learning vs Traditional Programming

Traditional Programming: This problem is meant to be solved via machine learning. The computer creates a rule after learning how the input and output data are related. Every time there is fresh data, the programmers do not need to design new rules. The algorithms change because of fresh information and experiences, increasing their efficacy over time (Figure 2).

Machine Learning Approach

Machine learning mimics human learning through experience, succeeding in familiar scenarios with easier predictions. Like humans, machines train by observing examples for precise predictions but struggle with new instances. Central to machine learning is learning and inference, primarily achieved by identifying patterns in data. A crucial skill for data scientists is selecting data to create a feature vector, simplifying reality with sophisticated algorithms. This feature vector transforms the learning step into a condensed model that describes the data. (Figure 4).

Key Points of Machine Learning Programs (Table 1)

Machine learning Algorithms

Machine learning can be grouped into two broad learning tasks: Supervised and Unsupervised. There are many other algorithms.

Supervised Learning: An algorithm learns the link between given inputs and a particular output using training data and feedback from humans. For instance, a practitioner can forecast sales using input data such as marketing expenses and weather predictions.

There are two categories of supervised learning:

· Classification task

· Regression task

Classification: To determine a customer's gender for a commercial, information is extracted from the database, including height, weight, occupation, salary, and purchase history. The classifier's goal is to assign a probability label (male or female) based on these features. Once the model learns to distinguish between genders, it can be used for predictions with new data. For example, if the classifier predicts a 70% probability of being male and 30% female, the algorithm confidently assigns the customer as male. Classifiers can have multiple classes for predicting items, like glass, table, shoes, each representing a different class.

Types of Algorithms:(Table 2)

Unsupervised Learning: In unsupervised learning, an algorithm explores input data without being given an explicit output variable (e.g., explores customer demographic data to identify patterns) (Table 3)

Machine Learning (ML) Algorithm and Practical Application
Numerous machine learning algorithms exist, chosen based on specific goals. In the following flower prediction example, ten algorithms predict flower types based on petal dimensions. The dataset is depicted in the top left image, divided into red, light blue, and dark blue groups. Classifications include the upper left of the second image in the red group, the middle exhibiting ambiguity and light blue, and the bottom in the dark category. Subsequent images illustrate various algorithms attempting to categorize the data. (Figure 7).

Machine learning as an AI subfield

Machine learning originated from AI research, initially exploring computers learning from data using symbolic techniques and "neural networks" like perceptron. These early efforts were later recognized as reimagined versions of generalized linear models in statistics. The divergence between AI and machine learning grew as AI favored a logical, knowledge-based approach, while machine learning focused on practical problem-solving using statistics and probability theory. In the 1990s, machine learning became a distinct field, moving away from the symbolic approaches of AI. The debate over whether all machine learning qualifies as AI persisted, with some arguing that only the "intelligent" subset does. Judea Pearl's distinction in The Book of Why emphasizes that AI involves active interaction for goal achievement, while machine learning relies on passive observations for learning and prediction.

Principal component analysis and cluster analysis

Feature learning is a vital preprocessing step for classification or predictions, utilizing algorithms to transform input data into a usable format without manual feature engineering. Supervised methods like supervised dictionary learning, multilayer perceptron, and artificial neural networks work with labeled data, while unsupervised techniques such as dictionary learning, independent component analysis, and autoencoders operate on unlabeled data. Manifold learning requires low-dimensional representations, enforcing sparsity through sparse coding techniques. Multilinear subspace learning directly extracts low-dimensional representations from tensor data. Deep learning hierarchically identifies abstract features. Intelligent machines separate variation sources through learned representations. Feature learning addresses the need for manageable data in machine learning tasks, with sparse dictionary learning (e.g., K-SVD) applied in various applications, linking new examples to classes based on the sparsest representation in the dictionary.

Analyzing Anomalies

Anomaly detection, a data mining process for outlier discovery, identifies unusual occurrences indicating issues like fraud or structural flaws. In the context of misuse detection, periods of inactivity are more intriguing than rare items. Traditional statistical outlier definitions pose challenges for unsupervised algorithms, prompting an alternative approach using cluster analysis to identify micro-clusters. Anomaly detection methods categorize into three groups: unsupervised strategies identify instances deviating most from the dataset; supervised approaches train a classifier on labeled "normal" and "abnormal" data; and semi-supervised techniques model normal behavior before assessing a test instance's likelihood of conforming.

Robot Learning: In developmental robotics, robot learning algorithms generate their own sequences of learning experiences, also known as a curriculum, to cumulatively acquire new skills through self-guided exploration and social interaction with humans. These robots use guidance mechanisms such as active learning, maturation, motor synergies and imitation.

Rule of Association: Association rule learning, a rule-based machine learning technique, identifies meaningful connections between variables in large databases using a metric of "interestingness." Agrawal, Imieliski, and Swami applied association rules to supermarket transaction data, revealing patterns like the likelihood of a customer buying hamburger meat when purchasing potatoes and onions together. This knowledge informs marketing decisions and finds diverse applications in areas like Web usage mining and intrusion detection. On the other hand, Learning Classifier Systems (LCS) are rule-based algorithms that combine learning components with genetic algorithms for rule discovery, focusing on context-dependent rules. Inductive Logic Programming (ILP) employs logic programming to represent input instances and hypotheses, finding utility in natural language processing and bioinformatics. Established by Gordon Plotkin and Ehud Shapiro, the foundational framework for inductive machine learning was implemented in their 1981 Model Inference System using Prolog to infer logic programs from examples.

Models: Creating a model that can process more data to create predictions after being trained on a set of training data is called ma- chine learning. Machine learning systems have been studied and used with a variety of models.

An Artificial Neural Network (ANN)

An Artificial Neural Network (ANN) emulates the interconnected structure of neurons in the human brain, with circular nodes representing artificial neurons and arrows indicating connections between them. Inspired by biological neural networks, ANNs, or connectionist systems, learn tasks through examples without specific rules. Each connection transmits a signal, and the network processes information through layers of artificial neurons, potentially with changing weights and thresholds. Originally designed to mimic the human brain, ANNs shifted focus to task execution, finding applications in computer vision, speech recognition, machine translation, social network filtering, games, and medical diagnosis. Deep learning, involving ANNs with multiple hidden layers, simulates how the brain processes vision and hearing, achieving success in computer vision and speech recognition.

A Decision Tree in ML

Decision tree learning uses a tree structure to move from item observations to predictions about the target value, applied in data mining and machine learning. It includes classification trees for discrete targets and regression trees for continuous values. Beyond data summarization, decision trees serve as formal tools for decision analysis, facilitating informed decision-making based on the resulting classification tree.

Support Vector Machines (SVMs) in ML

Support Vector Networks (SVMs), commonly known as Support Vector Machines (SVMs), are supervised learning techniques for regression and classification. The SVM training algorithm creates a model for binary, non-probabilistic, and linear classification, predicting whether a new example belongs to one of two categories based on labeled training examples. Using the kernel trick, SVMs can also perform non-linear classification by implicitly mapping inputs into high-dimensional feature spaces.

Analysis of Regression

Regression analysis utilizes statistical techniques to discern relationships between input variables and features. Linear regression, a common method, establishes a line using criteria like ordinary least squares to best fit the data. Regularization, such as ridge regression, mitigates overfitting and bias. Logistic regression addresses non-linear challenges in statistical classification, while kernel regression introduces non-linearity via the kernel trick. Effective machine learning models require representative data for comprehensive training, spanning text corpora, image collections, and specific customer information. The risk of overfitting and biased predictions underscores the importance of meticulous data preparation to avoid algorithmic bias and skewed outcomes.

Addressing cardiovascular diseases is critical, constituting 31% of global fatalities, according to the World Health Organization. The increasing number of AI-related papers in cardiovascular literature underscores the technology's potential impact on healthcare. (Figure 8).

AI applications in healthcare, while advancing and expected to enhance expert judgment, face a "black-box dilemma." The model, without user involvement, accepts input and produces results. In critical applications, especially in medicine or when replacing human roles with machines, this poses trust issues and potential catastrophic outcomes.

Its simplicity allows for the determination of each variable's significance in tree decisions, contributing to overall interpretability. Utilizing a random forest for feature selection falls under embedded approaches, combining the benefits of filter and wrapper techniques for high accuracy, improved generalization, and simplicity.

Main Features from the Actual Dataset were Selected for Analysis and Prediction:

1. Angina (Chest Pain): Angina is a type of discomfort or pain in the chest that develops when the heart muscle isn’t receiving enough oxygen-rich blood. Chest may experience pressure or squeezing. You may also experience pain in your back, neck, jaw, shoulders, or arms. Even the pain from angina can resemble dyspepsia.

2. Resting Blood Pressure: High blood pressure over a long period of time can harm the arteries that supply your heart. Your risk is even higher if you have high blood pressure together with another illness, such as diabetes, high cholesterol, or obesity.

3. Serum Cholesterol: The most likely cause of artery narrowing is a high level of Low-Density Lipoprotein (LDL) cholesterol, also known as “bad” cholesterol. Your risk of a heart attack is also increased by having high blood levels of triglycerides, a type of blood fat connected to your diet. Yet, having high levels of HDL cholesterol (the “good” cholesterol) reduces your risk of having a heart attack.

4. Fasting Blood Sugar: When your body doesn’t produce enough insulin or doesn’t respond to it appropriately, your blood sugar levels rise, which raises your chance of having a heart attack.

5. Resting ECG: The USPSTF comes to the conclusion with a moderate degree of certainty that, for individuals at low risk for cardio- vascular disease, the risks of screening with resting or exercise ECGs are either equivalent to or greater than the potential benefits. There is currently inadequate information to determine the balance between screening’s advantages and disadvantages for those at intermediate to high risk. The risk of a heart attack is reduced by (HDL) cholesterol, sometimes known as “good” cholesterol.

6. Maximum heart Rate Attained: The rise in cardiovascular risk brought on by the heart rate acceleration was equal to the rise in risk brought on by high blood pressure. The risk of cardiac death has been demonstrated to increase by at least 20% for every 10 beats per minute increase in heart rate, and this risk increase is comparable to that seen with an increase in systolic blood pressure of 10mmHg.

7. Exercise Induced Angina: The pain or discomfort associated with angina usually feels tight, gripping or squeezing, and can vary from moderate to severe. Angina is typically felt in the middle of the chest, but it can also affect one or both shoulders, as well as your back, neck, jaw, or arm. You can feel it in your hands as well. kinds of angina Angina Pectoris / Stable Angina / Unstable Angina Microvascular Angina c. Variant (Prinzmetal) Angina d.

On the test set, we achieved an accuracy of 91.7%.

Diagnosis of Heart Disease using Machine Learning

It covers symptoms, types of heart conditions, and key risk factors like age, sex, blood pressure, cholesterol, diabetes, and lifestyle choices. The work introduces machine learning approaches, including data mining, as essential tools for identifying cardiac diseases.

Logistic Regression Models in Predicting Heart Disease

This study predicts the risk of heart disease among the elderly using logistic regression models and data mining technology to identify key pathogenic factors. Comparing the accuracy with other algorithms, logistic regression proves valuable for heart disease prediction. Cardiovascular diseases, responsible for a significant global mortality rate, necessitate cost-effective and reliable prediction methods. Logistic regression, by extracting disease risk factors and providing real-time incidence probability, addresses this challenge, offering an efficient approach for early detection and improved quality of life, especially in low-income or developing countries.

iv. To check the behavior of the model with low to high training and testing data.

This study assesses the logistic regression algorithm's effectiveness in predicting heart disease by comparing its accuracy with other algorithms like Naive Bayes, SVM, and Neural Network. It aims to identify crucial characteristics and incidence probabilities for heart disease prediction. (Figure 24).

b) Algorithm: This paper focuses on the logistic regression model, widely used in machine learning for applications like data mining, disease diagnosis, and economic prediction. It specifically discusses its application in identifying risk factors for heart disease and predicting the probability of disease occurrence based on these factors. Logistic regression is commonly employed for classification tasks, especially those involving two categories, providing probabilities for each classification event.

Implementation: Logistic Regression Model: Dataset

The study collected data from the UCI machine learning repository, comprising 303 records with 14 attributes. Thirteen parameters served as eigenvalues for heart disease prediction, with one representing the output or forecast value for patients with heart disease ('num' for Numeric, 'nom' for Nominal). (Figure 25-36).

Data Analysis of heart diseases in the dataset

a) Data Preprocessing: To accommodate the logistic regression's dichotomous nature and the varying degrees of disease in the output values (0 to 4), data preprocessing was performed. Incomplete data were removed, and predictive attributes for heart disease were transformed from multi-category to binary values. Diagnostic values 2 and 4 were converted to 1, resulting in a final dataset with values of 0 (no heart disease) and 1 (potential heart disease). (Table 11-13).

Cardiovascular disease, a leading cause of global mortality, necessitates early diagnosis for timely intervention. This study employs Logistic Regression (LR) on the UCI dataset to classify cardiac disease. Enhancements include data pre-processing through cleaning, handling missing values, and feature selection based on positive correlations with the target value. The LR model achieves an accuracy of 87.10% with a dataset split ratio of 90:10 for training and testing. (Table 14).

Machine learning, a crucial field for rapidly extracting valuable information from vast datasets, employs powerful models to uncover hidden patterns and correlations. Logistic regression classifiers yield accurate results in this context. (Table 15).

Various ML algorithms, including logistic regression, decision tree, and support vector machine, were tested on the UCI dataset. Logistic regression achieved an accuracy of 82.56%, while logistic regression support vector machine reached 84.85%. (Table 16).

Logistic regression was tested with the UCI dataset at various ratios, and the table below illustrates the accuracies. The model achieved 87.10% accuracy with a training-testing split ratio of 90:10, showcasing improved accuracy with increased training data. (Table 17).

In the medical field, predicting cardiovascular disease is crucial, utilizing patient data to discern its presence or absence. Logistic Regression, a supervised machine learning algorithm, is employed for classification in this study. Enhancing performance involves preprocessing steps like cleaning and handling missing values. Feature selection is a vital aspect, contributing to algorithm accuracy and behavior.

b) Feature Selection: Apart from predicting heart disease probability, the experiment aims to identify key factors contributing to heart diseases. To achieve this, feature extraction is conducted before data analysis, aiming to unveil the pertinent pathogenic factors influencing heart issues. The focus is on understanding the relationship between age, blood pressure, and various characteristic values, providing insights for preventive health measures. (Figure 29,38).

According to the correlation between the eigenvalues, the combination with the most significant features was selected for data analysis, and different data mining techniques were used to test the selected combination.

Heart Disease Prediction using Exploratory Data Analysis

The healthcare industry handles vast volumes of big data, holding valuable insights for informed decision-making. Exploratory Data Analysis (EDA) in healthcare involves scrutinizing data for errors, identifying correlations among variables, and deriving patterns without statistical modeling. EDA is crucial for accurate predictions and preventive care, contributing to improved healthcare outcomes. This paper employs K-means clustering for predicting heart disease risk factors, analyzing a dataset with attributes like age, chest pain type, and blood pressure. The study emphasizes pre-processing, classifier performance, and evaluation metrics, demonstrating accurate predictions through visualized data.

Human-generated data has exceeded ten exabytes, highlighting the significance of EDA. The method uncovers hidden structures, identifies anomalies, and builds models to test assumptions. EDA is categorized into graphical/non-graphical and univariate/multivariate methods. Diagnostic methods in healthcare include invasive (incise procedures) and non-invasive approaches. Machine learning algorithms for non-invasive methods, such as SVM, K-means clustering, KNN, ANN, and Naive Bayes, play a vital role in disease diagnosis.

Heart Diseases

Heart disease, considered globally as the deadliest ailment, poses challenges in early diagnosis and treatment due to insufficient medical resources and personnel. Invasive techniques, relying on medical history and physical reports, are time-consuming and imprecise. Predicting heart disease based on symptoms like age and pulse rate using data analysis in healthcare is crucial for early detection and effective treatment. Technologies like ECG aid in screening irregular heartbeats. Risk factors include obesity, smoking, diabetes, blood pressure, and unhealthy diet. Unusual forms of heart disease, like acute spasms in coronary arteries, can lead to oxygen deprivation, affecting physiological systems beyond the heart. Early diagnosis is paramount for minimizing risks and enhancing the quality of life for heart patients.

Results and Discussion

This section presents the results of data analysis for predicting heart diseases, considering variables such as age, chest pain type, blood pressure, blood glucose level, ECG, heart rate, exercise angina, and four types of chest pain. The heart disease dataset undergoes effective preprocessing, eliminating unrelated records and handling missing values. The K-means algorithm is then applied to compose the preprocessed dataset, discussing four types of heart diseases: asymptomatic pain, atypical angina pain, non-anginal pain, and non-anginal pain. Histogram analysis shows a higher risk of heart disease in the age range of 50 to 55, where the development of coronary fatty streaks begins. (Figure 31).

Microbiome-Based Cardiovascular Disease Diagnostic Screening Using Machine Learning:

Cardiovascular disease (CVD), encompassing conditions like heart failure, hypertension, and atherosclerosis, poses a significant global health threat with an estimated death toll exceeding 23.6 million by 2030. To comprehensively assess cardiovascular health, various clinical procedures, including electrocardiogram (ECG), chest x-ray (CXR), and echocardiography, are often necessary. A rapid screening test could streamline this diagnostic process and facilitate timely and effective treatment. Utilizing QIIME 2, the BIOM file underwent further processing, excluding samples with a total frequency of less than 10,000. The resulting filtered BIOM file was employed to generate the Operational Taxonomic Units (OTUs) table for subsequent analysis, involving stool 16S data from 478 participants with CVD and 473 without CVD.

Statistical Analysis: ML Algorithms

The LDA score greater than 2.0 and the Kruskal-Walli’s test determined the cutoff for discriminating features, utilizing 50 separate iterations for mean and standard deviation calculations of AUC, sensitivity, and specificity in ML modeling. Supervised ML models, enhanced with 39 taxonomic features, were employed to predict CVD and non-CVD classification. Testing five ML algorithms for CVD versus non-CVD classification revealed RF and NN outperforming others with an AUC of 0.58, while EN, SVM, and DT achieved 0.57, 0.55, and 0.51, respectively. RF and NN showed lower sensitivity but greater specificity compared to EN, DT, and SVM. (Table 27).

For improved diagnostic classification and reduced feature space dimensionality, the top 500 high-variance OTU features were utilized to select High-Contributing OTU Features (HCOFs) in a Random Forest (RF) model. Training the RF model with the top 100 HCOFs, based on variable significance scores from 0 to 100, resulted in improved testing AUC (to 0.70). Re-implementing the RF method with the top 20, 25, 50, 75, and 100 HCOFs revealed outperformance by models trained with the top 20 and 25 HCOFs, demonstrating robust diagnostic classification for identifying individuals with CVD. (Table 28).

Discussion

This study explores the relationship between gut microbiota and cardiovascular health, aiming to identify cardiovascular disease (CVD) using gut microbiota information. It assesses supervised machine learning models' performance with top 500 high-variance Operational Taxonomic Unit (OTU) features, measuring AUC, sensitivity, and specificity. Seeking common early warning indicators for CVD, the analysis investigates if gut microbial composition changes can serve as markers. Successfully using gut microbiome data for supervised machine learning, the study demonstrates promising predictive capabilities. The approach, novel for CVD, benefits from a large sample size (478 with CVD, 473 without), offering valuable insights without specific variable constraints.

The cohort represented various characteristics, allowing for a tolerant experimental design investigating ML model capability using gut microbiota for diagnostic classification of non-CVD vs. CVD. Acknowledging gut microbiota's susceptibility to additional factors, such as diet and medicine, the American Gut Project data lacked comprehensive assessment in the current ML analysis. Despite potential misreported or undiagnosed CVD cases, distinct gut microbial fingerprints were found between groups, indicating changed gut microbiota as a common factor in CVD manifestations. Initial ML modeling with differential bacterial taxa achieved a 0.58 AUC, prompting exploration of OTUs for increased predictive potential. Selecting top 500 high-variance OTUs, the RF model achieved an improved AUC of 0.65, with further enhancement to 0.70 using only 25 OTU characteristics. This study, unique in stool sample-based ML, outperforms previous approaches, showing promising potential for microbiome-based ML in predicting CVD, encouraging future calibration and improvement.

Perspectives

The AI-driven ML modeling offers promising potential for practical diagnostic screening of CVD using gut microbiota composition. This supervised ML approach could serve as an initial tool for routine cardiovascular health monitoring before resorting to various clinical tests. The presented ML-based feature selection method highlights significantly contributing OTUs, showcasing that a small number of informative OTUs not only reduce computational complexity but also enhance diagnostic classification abilities. With hypertension being a major CVD risk factor, this technique could be applied for regular monitoring of cardiovascular damage caused by hypertension. The study identifies gut microbiome traits associated with cardiovascular health and disease, emphasizing the strong segregation of gut microbiota signatures between non-CVD and CVD subjects. This study marks the successful application of AI-driven gut microbiome-based ML modeling for potential CVD diagnostic screening.

Exploratory Analysis of ML Application in Diagnoses of Heart Problems

The initial exploration of this dataset involves checking the proportion of patients in each class. Among the 296 individuals, 160 belong to class "1," signifying good health, while 136 are in a different class, indicating a risk of developing heart disease. The dataset appears balanced in accurately representing both classes. (Figure 42).

The correlation between variables is examined, and the presence of high correlation implies redundancy among them (Figure 43). However, in the correlation matrix shown, there is no evident association between any variables. Consequently, none of the variables can be dismissed as they may all contribute to the classification of the condition. Subsequent figures will explore the connections between both target classes and the various variables. (Figure 44).

Although achieving an accuracy value of 0.84 on the training dataset by utilizing a 10-fold cross validation and fine-tuning the various parameters, the accuracy of the decision tree suffered from overfitting and fell to 0.75 on the test dataset. Figures 5-5 and 5-6 display the AUC curve and confusion matrix, respectively (Figure 57

The decision tree specifically struggled with sensitivity for the group of healthy individuals, where it received a recall of 0.6. The mod- el’s f-1 score was 0.78 for class 0 and 0.71 for class 1, respectively. The same applications were run on SVM and ANN, and table 5-1 displays a summary of all outcomes (Table 29).

Table 29 summarizes results from various strategies, with logistic regression standing out as the top-performing model across metrics, achieving 85% accuracy and a 94% AUC. Feature importance is assessed using permutation significance, revealing the LR model's crucial feature, "ca," impacting accuracy. Positive values indicate significant features, while negative numbers suggest improved accuracy after rearranging certain features.

Descriptive Statistics and Exploratory Data Analysis:

This section encompasses both descriptive statistics and exploratory data analysis. Out of the 14 data properties, only five are numeric, and the table includes information on four of them. The "Old peak" attribute is omitted from the table due to its conclusions necessitating a comprehensive understanding of heart physiology. (Table 30).

Figure 11 shows the heart health statuses (0, 1, 2, 3, and 4), which range from extremely healthy to very ill. Male and female populations are shown by blue and green bars, respectively. It is clear from this data set that men are more likely than women to have cardiac disease. The Chi-square test is used to confirm the null hypothesis, H0, which is proposed. The null hypothesis asserts that there is no association between disease and population gender; if this hypothesis is disproven by the chi-square test, the hypothesis that there is some correlation between disease and population gender is established (Table 32).

0,1,2,3,4 are the columns spanning from no heart disease to highly unhealthy heart disease, and their total values are 164, 55, 36, 35, and 13 accordingly. In Table 32, there are 206 men and 97 women in total (Table 33).

The anticipated number of ill patients is determined in Table 33. The two rows of men and women with the five columns (0, 1, 2, 3, 4). (R-1) * (C-1) are the degrees of freedom for this table, where R and C are the corresponding rows and columns. The degree of freedom is therefore 4.

Experiments

The dataset underwent testing with various machine learning algorithms. Initially, the study modeled the dataset without feature selection and obtained results. In the second phase, modeling was done exclusively using features from SBS. Methodologies such as parameter tweaking and k-fold cross-validation were applied across all studies. K-fold cross-validation aids in determining suitable parameters for the model, while parameter tweaking helps prevent over- and under-fitting in the dataset.

Results

Table 36 reports a Nil entry for Naive Bayes, as it requires no parameter tweaking. Therefore, the performance result from Table 8 was used for comparison. KNN performance decreases after parameter adjustment. Post-adjustment, SVC outperforms Naive Bayes, Random Forest, and other models. It's worth noting that log loss, being negative and potentially exceeding one, is unique among performance measures. (Figure 51).

Table 41 ANN employs the “adam” algorithm as an optimizer and three hidden layers. The Keras machine learning package was used to parameterize the ANN.

Observations and Findings:

Algorithm performance varies based on factors like cross-validation, grid search, calibration, and feature selection. Each method excels under different circumstances. Random Forest performs better with numerous datasets, while Support Vector Machine excels with a limited number of datasets. Interestingly, algorithm performance improves without boosting in non-feature-selected data but deteriorates with feature-selected data. However, after boosting in feature-selected data, performance improves, emphasizing the importance of feature selection before boosting. Performance measurements are commonly employed for dataset comparison after feature selection, parameter adjustment, and calibration.
