After feature extraction, 1 × 368 features have been selected for each image using the ReliefF Iterative Neighborhood Component Analysis (RFINCA) feature selection algorithm. Selected features are classified using K Nearest Neighbor (KNN) algorithm.

Forward Iterative Feature Selection Based on Laplacian Score
Web10 aug. 2012 · This paper presents an iterative feature selection method to deal with these two problems. The proposed method consists of an iterative process of data sampling followed by feature ranking and finally aggregating the results generated during the iterative process. WebBackward Feature Elimination is an iterative approach. It starts with having all features selected. In each iteration, the feature that has on its removal the least impact on the models performance is removed. Genetic Algorithm is a stochastic approach that bases its optimization on the mechanics of biological evolution and genetics. Web1 jul. 2024 · Moreover, a 2-layered feature selection method is proposed using ReliefF and iterative neighborhood component analysis (RFINCA) to solve the feature selection problem. The goals of the RFINCA are to choose the optimal number of features automatically and use the effectiveness of ReliefF and neighborhood component … arab news lebanon
