Does a hybrid stacked autoencoder and SVM-based expert system improve heart failure detection accuracy compared to conventional SVM models?
A novel hybrid machine learning system combining stacked autoencoders and SVMs demonstrated high accuracy (97.78%) in detecting heart failure using a reduced set of clinical features.
Kamal et al. (2026) studied Heart failure (n=297). Hybrid Stacked Autoencoder and Support Vector Machines vs. Conventional SVM, L1 and L2 Regularized SVMs was evaluated on Accuracy, Sensitivity, Specificity, Matthews correlation coefficient (MCC). The proposed expert system for heart failure detection achieved a testing accuracy of 97.78%, sensitivity of 97.56%, specificity of 97.96%, and an MCC of 0.955.
