The Credit Card Fraud Detection Dataset has 30 numerical input features, out of which \(V_{1}, V_{2},..., V_{28}\) have undergone numerical transformation using Principal Component Analysis (PCA) for data analysis and feature reduction purposes. However, the “Time” and “Amount” featu...
Machine learning (ML) methods have been playing an important role in the design and discovery of perovskite materials, while feature selection as a dimensionality reduction method has occupied a crucial position in the ML workflow. In this review, we introduced the recent advances in the ...

To reduce computational complexity and to eliminate information redundancies and irrelevant features, we improved upon a multidimensional time series feature selection method to achieve dimension reduction. The improved method selects features through the combination of the Kozachenko–Leonenko (K–L) ...
