In this work, we will evaluate the impact of independent component analysis (ICA) on a breast cancer decision support system's feature reduction capabilities. The Wisconsin Diagnostic Breast Cancer (WDBC) dataset will be utilised to construct a one-dimensional feature vector (IC). We will study the performance of k-NN, ANN, RBFNN, and SVM classifiers in spotting mistakes using the original 30 features. Additionally, we will compare the IC-recommended classification with the original feature set using multiple validation and division approaches. The classifiers will be tested based on specificity, sensitivity, accuracy, F-score, Youden's index, discriminant power, and receiver operating characteristic (ROC) curve. This effort attempts to boost the medical decision support system's efficiency while minimising computational complexity.
