ABSTRACT Cardiac disease is a chronic condition that impairs the heart’s functionality.It includes conditions such as coronary artery disease,heart failure,arrhythmias,and valvular heart disease.These conditions can lead to serious complications and even be life-threatening if not detected and managed in time.Researchers have utilized Machine Learning(ML)and Deep Learning(DL)to identify heart abnormalities swiftly and consistently.Various approaches have been applied to predict and treat heart disease utilizing ML and DL.This paper proposes a Machine and Deep Learning-based Stacked Model(MDLSM)to predict heart disease accurately.ML approaches such as eXtreme Gradient Boosting(XGB),Random Forest(RF),Naive Bayes(NB),Decision Tree(DT),and KNearest Neighbor(KNN),along with two DL models:Deep Neural Network(DNN)and Fine Tuned Deep Neural Network(FT-DNN)are used to detect heart disease.These models rely on electronic medical data that increases the likelihood of correctly identifying and diagnosing heart disease.Well-known evaluation measures(i.e.,accuracy,precision,recall,F1-score,confusion matrix,and area under the Receiver Operating Characteristic(ROC)curve)are employed to check the efficacy of the proposed approach.Results reveal that the MDLSM achieves 94.14%prediction accuracy,which is 8.30% better than the results from the baseline experiments recommending our proposed approach for identifying and diagnosing heart disease.

1 Introduction

The heart is considered the most critical organ in the human body.It does its primary job when the heart pumps blood and oxygen throughout the body[1].The brain,kidneys,and other vital organs will suffer if the heart is not working correctly.Heart disease is one of the leading causes of death globally[2].Heart disease claimed the lives of 17.9 million people in 2019[3],according to the World Health Organization(WHO).Heart disease is caused by a lack of oxygen and blood flow,lifestyle changes,and contemporary dietary habits[4].The vast number of heart disease risk variables enables the researcher to establish the best forecast method [5].Cigarette smoking increases the risk of heart disease and stroke.Other risk factors include an aging population,high blood pressure,diabetes,high cholesterol,and hypertension.These include discomfort in the jaw,neck,arms,shoulders,and stomach,tinniness of breath,and back pain as signs of heart disease[6].

Right ventricular-arrhythmogenic cardiomyopathy and hypertrophic/dilated/hypertrophic cardiomyopathy are a few hereditary cardiac diseases.The severity of these symptoms varies from person to person.The projection is based on current trends and offers outcomes.Preventative measures are necessary to forecast cardiac disease and act before it affects individuals [7].If discovered early,cardiovascular mortality may be reduced.Manually analyzing symptoms is challenging because of many attributions,multiple duplications,incompleteness,and a direct connection to the era via medical records.It is also challenging to properly treat patients after manually analyzing enormous volumes of data on heart illness[8].Because of the difficulty in predicting Cognitive Health Disease(CHD)due to many risk factors,this disease is more expensive to diagnose and treat.There are more treatment choices for all illnesses,but the accuracy and risk factors associated with heart disease deteriorate with time.Patients only become aware of the symptoms as the condition progresses,making it difficult for doctors to treat them [9].Many conventional and manual methods of collecting and evaluating clinical data are confined to hospitals.Medical facilities have substantially attempted to address this restriction by combining massive data sources with new technology.However,many still need to adopt new systems as early as possible because of the increasing data complexity;techniques like data mining and ML are becoming more popular[10–12].

Healthcare data analysis is becoming more attractive owing to the fast and continuous advancement of Active Learning(AL)methodologies in various industries[13,14].One of the most prevalent strategies is active learning to learn from poorly labeled data.According to research,unlabeled and imbalanced data are more widespread in the real world than labeled data.Training an effective prediction model with limited labeled examples is critical since label collection is sometimes costly because human experts are involved.To get around this issue,AL uses only the most insightful measures in-class assignments [15].This tool aims to look for the most appropriate examples to annotate data.Despite the abundance of unlabeled data,labeling is relatively inexpensive.Active learning algorithms must choose the best examples to query based on the proper criteria.Active learning algorithms often pick queries based on their informativeness and representativeness.The informativeness of a particular instance measures how well it may minimize the uncertainty in a statistical model.When determining a sample’s representativeness,look at how well it can reproduce data input patterns that are not explicitly labeled[16].

ML is being used to develop prediction models to handle and analyze vast amounts of complex medical data.In this way,the computer may use data to find patterns and make judgments.It offers a great deal of diagnostic potential.Approaches based on machine learning allow a computer to make decisions based on an internal mathematical model about what is most possible.Traditional methods of making accurate predictions take much longer than machine learning algorithms.Machine learning helps doctors predict their patient’s health by obtaining medical data from patients.Before ML’s full potential,the engagement of doctors needed to be more utilized.Heart disease may be diagnosed by applying several machine-learning approaches to an optimal dataset.Researchers have a significant challenge when attempting to make predictions about heart disease.Modern medicine has a major challenge in determining when a patient may develop cardiac disease.Many wealthy countries’leading killer is heart disease.Every year,it claims the lives of almost one in every four Americans.Because of its effect on blood vessel function and the development of coronary artery infections,heart disease affects the body,particularly in adults and the elderly[17,18].

In this study,the proposed approach solves the problem of heart disease detection without human intervention.By addressing the limitations outlined above,this study contributes to the identification of heart disease more effectively and efficiently:

? Propose an approach based on machine learning and deep learning-based stacked model to detect heart disease,where classifiers participate in voting-based decision-making.

? Evaluate the proposed method in comparison with other approaches,such as DT,RF,NB,XGB,DNN,and finetuned NN,to see the effectiveness.

? According to the experimental findings,the proposed approach improves accuracy by 8.30%compared to previous best practices.

Section 2 provides an overview of the relevant literature.Section 3 details the recommended proposed approach for heart disease detection.Section 4 presents the results and comparative analysis.Section 5 concludes the work and provides potential directions for further investigation.

2 Literature Review

Health and medicine are among the many domains where machine learning has prompted considerable interest.A variety of machine learning algorithms have been developed for the detection of heart illness.This has led to research on developing medical applications using different ML algorithms and approaches.

This study improved the prediction performance using the chi-square feature selection technique.Cross-validation has been used to choose the best model [19].Experimental findings show that the suggested approach is more accurate than previous methods.This work suggested employing the UCI machine learning repository’s Cleveland heart disease dataset,which consists of only 303 cases,to predict heart illness using machine learning[20].This study’s KNN classifier has an accuracy rate as high as 87%.According to[21],logistic regression is the most effective method for predicting illness.It scored 89%higher than KNN,Support Vector Machine(SVM),DT,and RF.Shows neural network methods that include estimated values from several earlier strategies and a prior probability [10].A computer algorithm can forecast the possibility of heart disease based on main symptoms,claims recent research[22].The Neural Networks approach is a solid bet when making accurate predictions using machine learning.Compared to past research,this model reaches an accuracy of up to 89.01%,which is a remarkable result.Three hundred-three data with 13 characteristics are obtained by the work of[23]to identify heart disease.An SVM-linear kernel had the most fantastic accuracy of 86.8%,followed by KNN and NB for classification.

Authors in[24]proposed an ensemble learning approach for Diagnosing Cardiovascular Diseases(CVD)by combining multiple modalities of patient data.They used ResNet-50 as a base learner and logistic regression,support vector machine,random forest,and XGB as a meta learner.They used a dataset of 1,677 patients with cardiovascular conditions,including coronary artery disease,heart failure,and hypertension.The patient data included demographic information,clinical history,and a range of diagnostic test results,such as electrocardiograms and echocardiograms.They achieved an accuracy of 90.5% for diagnosing CVD,outperforming all individual modalities and traditional machine learning approaches.Authors in[25]proposed an integrated machine-learning approach to diagnose Coronary Artery Disease(CAD)severity.They used a dataset of 303 patients with suspected CAD who underwent coronary angiography.The patient data included demographic information,clinical history,laboratory results,and angiographic data.They achieved a high accuracy of 94.0%.The authors suggest that this approach can potentially improve the accuracy and efficiency of CAD diagnosis,leading to better patient outcomes.

Various strategies are used in the proposed endeavor[26]to increase the accuracy of test findings.The suggested diagnostic system[27]uses the random search algorithm to identify features,whereas the RF model predicts heart failure.The proposed method is optimized using a grid search technique.The suggested technique uses Reptile Search Algorithm(RSA)to uncover features and update the RF classifier to correctly predict and categorize heart disease.Heart attack risk may be predicted using an SVM and principal component analysis (PCA),including age,blood pressure,artery thickness,and more.In another study,87%accuracy is achieved using the SVM model with PCA component,according to experimental data.Chi-square and PCA feature selection techniques are employed in this study[28].Six classifiers are utilized in the classification task.Authors argue for using Convolutional Neural Network(CNN)architecture to diagnose cardiac disease and predict its onset more accurately than current models such as SVM and RF.

Authors in[29]proposed the expert system,which uses an SVM and two other models to predict heart failure accurately.In the first SVM model,the coefficients of L1 regularised(used to measure the loss)are set to zero.In the next SVM model,the loss is calculated by L2,which is used as a forecasting model.The recommended method’s effectiveness is evaluated based on six key factors.According to the research,using the new approach,a standard SVM model’s quality is improved by 3.3%.This research employs several classification methods,such as KNN,SVM,NB,Multilayer Perceptron(MLP),and Artificial Neural Networks (ANN).This study used two more approaches,Particle Swarm Optimization(PSO)and Ant Colony Optimization(ACO),to improve the model accuracy.An improved classification model had a maximum accuracy of 99.65%.There are strong indications that our suggested approach is superior in performance to the previously discussed categorization method[30].A technique proposed by [31] uses real-world coronary heart disease data to provide extensive and reliable categorization rules for diagnosing the ailment.The N2 Genetic-nu-SVM approach has an accuracy of 93.08% obtained from Coronary-artery-disease (CAD) detection in Iranian patients after data pre-processing with normalization was used[32].Because of the research,it was shown that the suggested technique could produce highly accurate CAD detection rules.

Some studies focus on the classification of heart disease but lack a reasonable detection rate.Most did not focus on providing a promising F1-score,the best indicator for imbalance,and did not focus on balancing data.

3 Proposed Approach

This section explains the procedure for modeling predictions about heart disease.Fig.1 illustrates the proposed research approach.There are numerous stages to this process.Starting with selecting a dataset for the experiment.Experiments are carried out using the heart disease dataset.Many tasks must be accomplished before model training in the pre-processing stage.Because the dataset is unbalanced,a more accurate model assessment is impossible.Hence,it is essential to balance the data before model training.Multiple machine-learning and deep-learning classifiers are used for experiments to identify the significance of the features extracted from the data.This research also looks at deep learning approaches for detecting the presence of heart disease.Two deep neural network classifiers measure how well deep learning models perform on a dataset.Random Forest(RF),Decision Tree(DT),K-Nearest Neighbour(KNN),and Extreme Gradient Boosting(XGB)are all utilized to determine the presence of heart disease.

3.1 Dataset Selection

This study used clinical and pathological data for heart disease detection and prediction.The dataset is now publicly available at Kaggle (https://www.kaggle.com/datasets/aasheesh200/framingham-heart-study-dataset).There are 4,240 patient data available in this database,with 644 patients with heart disease and 3,596 medical records about healthy individuals.The dataset contains 16 Attributes.The attributes present in the dataset and the description of each attribute with its data types are shown in Table 1.The value 0 in the target column indicates that the patient does not have heart disease,and the value 1 shows that the patient suffers from heart disease.

Table 1:Dataset attributes description

3.2 Data Pre-Processing

Machine learning depends heavily on pre-processing data to evaluate its quality and extract essential information that might affect the model’s performance.Pre-processing is required before training a model.Addressing different dataset features,managing missing values,scaling,and standardization are all handled in the preparation step.Handle over-fitting,class imbalance,and label encoding are part of this process.To show the model’s efficiency and obtain acceptable and reliable results to get an efficient prediction,this study advises removing abnormalities(outliers)and applying a standard scaler to standardize the dataset.A standard scaler is used to keep the data consistent.It modifies the distribution’s mean and standard deviation features to zero and one.As defined in Eq.(1),standard scalers are based on St,the standardized version ofYj.

To address this issue,data balance was accomplished using the smote approach[33].Oversampling and undersampling are two methods used in this procedure.It creates artificial samples for the marginalized minority.This strategy is much easier to overcome the overfitting problem of random oversampling.After completing the data balancing process,3394 health and heart disease patients are in the database.We also identify the missing values from the dataset and found missing data in the education,Risperdal,BPMeds,totChol,BMI,heart rate,and glucose columns.The glucose column had the most missing values,which was filled up using the data’s mode of 75.0.Other missing values from various columns are deleted since they did not significantly contribute to the dataset.Our dataset’s totChol and sysBP columns have Removable Outliers that may be removed.Identify outliers by checking the highest and minimum quartiles and removing the rows that include the outliers.

Pearson’s coefficient(PCC)eliminates unnecessary,duplicated,and redundant features from the data.Correlation coefficients range from -1 to 1,depending on the data.For values around -1,features are loosely connected and have little effect on model performance.For values near 1,features are firmly coupled and significantly impact model performance.When calculating the PCC,a 0.85%threshold is used.If the correlation value is higher than this threshold,the feature is discarded;if it is lower,it is maintained.After doing a feature co-relation analysis,all attributes are identical.

3.3 Feature Extraction

To classify data correctly,it is essential to identify the appropriate characteristics.According to Fig.2,the RF feature selection method identifies the important 10 features.It aims to reduce dimensionality by selecting the essential feature that may improve the models’performance.Even in machine learning approaches,this is a common feature selection strategy that has proven effective.

3.4 Classification Models

Our experiment used RF,DT,KNN,XGB,and two deep learning models,FT-DNN and K-DNN,for heart disease detection.This paper offers two approaches to increase classification accuracy: a machine-learning-based ensemble model (DT,XGB,and KNN) and an MDL-stacked model (ML ensemble model with FTDNN and K-DNN).This section will explain how to apply the ML ensemble classifier and DL techniques to diagnose heart disease accurately.

3.4.1 Machine Learning Ensemble Classifier

Researchers have solved Various ML challenges using Ensemble Learning (EL) [34,35].Each dataset comprises various issues;EL identifies distinct diseases and classifies data.Use a variety of ML classifiers and voting methods to boost performance.Every time a new piece of data is received,each classifier in the ensemble assumes its class label.The majority of classifiers predict that the class label or the class label with the highest votes is the one that is utilized in that instance.These tactics are superior to the traditional single-learning approach to achieving more excellent generalization outcomes.The suggested ML ensemble classifier employs a weighted majority technique to combine the predictions of many classifiers.The best results are presented once each categorization model has been finetuned.

K-Nearest Neighbor(KNN)is a fundamental regression and classification ML method.Similar measures(such as the distance function)are employed in KNN calculations to characterize new points.The similarity of the items being compared is what drives the KNN computation.According to KNN,a neighborhood’s categorization is decided by the majority of its near neighbors.The data point is labeled with the class that has the most neighbors.There may be an improvement in accuracy and choice of k as the number of closest neighbors increases.The Sklearn library’s default parameter settings are utilized in this study.

Extreme Gradient Boosting (XGB)is a memory optimization technology that boosts system performance using less memory.An EL approach employs XGB to improve classification accuracy.It is possible to apply the XGBoost algorithm to a large dataset.Gradient boosted trees’open-source counterpart,XGBoost,is well-known and influential.A weak learner may translate an input data point into a continuous score using regression trees when gradient boosting is employed for regression.XGBoost reduces a regularised loss function at the L1 and L2 levels.New trees are created to anticipate the residuals or errors of prior trees,combined with the previous trees,to get the final prediction.One may utilize gradient boosting to reduce the loss while adding new models.

Decision Tree (DT)can be employed effectively for categorical and numerical data.A tree is a good analogy because of the way it is organized.DT is the most often used approach when dealing with medical data.Establishing a reliable and repeatable data-gathering procedure is as easy as building a decision tree.This model utilized the default parameters when trained on the provided dataset.

3.4.2 Deep Learning Classifier

As DL-based classifiers,deep neural networks consist of various dense layers.DL-based classifiers are employed to assess the classification performance of heart disease to conduct a comprehensive research.In this research,the Variant of the Recurrent Neural Network(RNN)model,which is Logn Short Term Memory(LSTM),was also used.However,it could have performed better on the provided data because of the insufficient data.Binary cross-entropy is used to calculate the loss of the FT-DNN model,and a learning rate of 0.001 is used in this study.Relu activation function with ten dimensions and a 16-unit value is used in the first layer,and the following three layers used unit values of 12,8,and 4.In the end,a fully connected layer is used.The fully connected layer uses a sigmoid activation function directly linked to the value the model tries to predict.The input layer of the FT-DNN model has 176 parameters with a unit value of 16.There are 204 parameters in the next layer with 12 units.The second hidden layer of the FT-DNN model comprises 104 parameters with eight units,while the fourth and last hidden layer contains 36 parameters with four units.Thus,the FT-DNN model includes a single input layer,three hidden layers,and an output layer with a sigmoid activation function.Only 525 parameters to pick for training.

All the parameters can be figured out,and the proposed model did well on the test data.The second DNN model is DNN;a robust medical disease detection approach was employed to avoid overfitting.A healthcare disease detection model named DNN controls overfitting after shrinking the dataset by eliminating outliers.The DNN model uses an Adamoptimizer and Binary cross-entropy to calculate the loss to simplify finetuning.The proposed DNN model includes just one input layer.There is finally only one linked layer after so many hidden ones.There is only one fully connected layer after so many hidden layers.The input layer calculates a total of132parameters.Subsequently,there are130characteristics buried further deeper.The third and fourth hidden layers each include 88 parameters for 411 training parameters.Fig.3 depicts the deep learning model architecture used for heart disease prediction.

4 Results and Discussion

This section summarizes and contrasts the essential findings with the standard baseline methods.Classifier performance for heart disease identification using ML and DL classifiers is the primary focus of this work.The heart disease dataset was used in this study’s experiments.This research included ML and DL approaches.The two methods are used to carry out the tests.Deep learning algorithms are used in the second phase of our research.DL models performed poorly due to a lack of data;thus,an MDL Stacked model is created,a combination of ML Ensemble and DL models,to improve the poor results of DL models.The MDL Stacked obtained the highest results and performed well on the heart disease dataset.The accuracy,precision,recall,F1-score,confusion matrix,and area under the Receiver Operating Characteristic(ROC)curve are some performance metrics employed in this research.70%of the data is utilized for training the ML and DL models,while the remaining 30%is used to assess the model’s accuracy.The GPU named GTX 1050 with a 2 GB VRAM laptop with an i5-8300H processor and 16 GB RAM was used to run Python 3 and a Jupyter notebook.

5 Conclusion and Future Work

Among the most prevalent health problems nowadays is heart disease.Several machine learning techniques,deep learning,and ensemble learning methods were suggested in this research as potential tools for improving heart disease prediction.The MDLSM was found to be the most reliable predictor of heart disease.We also thoroughly compared the baseline technique and discovered a notable improvement in the outcome.The ideal attributes for our future work can be determined in various ways.To increase the evaluation’s accuracy,more datasets can be employed.By gathering and growing more data,deep learning techniques better handle the prediction problem and produce better results.
