Abstract: In recent years, medical technological innovators have focused on diverse clinical therapies to find innovative ways to overcome clinical challenges. But still, there emerge certain drawbacks like high computational cost, increased error, less training ability, the requirement of high storage space and degraded accuracy. To conquer these drawbacks, the proposed research article presents an innovative cascaded extreme learning machine for effective heart disease (HD) prediction. Missing data filtering and normalization methods are carried out for data pre-processing. From the pre-processed data, the features are extracted using the Framingham risk factor extraction module, whereas the extracted features are fused to generate a feature vector. The most significant features are selected using Rhino Satin Herd optimization algorithm. Using a linear weight assignment approach, the feature weighting process is undertaken by allocating higher weights to significant features and less weight to unwanted features. Finally, classification is performed through the Cascaded kernel soft plus extreme learning machine with a stacked autoencoder model. The performance is analyzed using PYTHON to evaluate the superiority of the proposed model. The proposed model obtained an overall accuracy of 90%, precision of 94%, recall of 91.3% and F1 measure of 92.6% in the Cleveland-Hungarian dataset, which is comparatively superior to the existing methods. An accuracy of 92.6% is attained for predicting HD in terms of the heart patient dataset. The proposed model attains better performance because of effective accuracy outcome, reduced overfitting issues, fewer error rates, better convergence and training ability.
