mdl = fscnca(X,Y) performs feature selection for classification using the predictors in X and responses in Y. fscnca learns the feature weights by using a diagonal adaptation of neighborhood component analysis (NCA) Run the command by entering it in the MATLAB Command Window. Description. inmodel = sequentialfs(fun,X,y) selects a subset of features from the data matrix X that best predict the data in y by sequentially selecting features until there is no improvement in prediction. Rows of X correspond to observations; columns correspond to variables or features.y is a column vector of response values or class labels for each observation in X. Dimensionality Reduction and Feature Extraction PCA, factor analysis, feature selection, feature extraction, and more Feature transformation techniques reduce the dimensionality in the data by transforming data into new daniel-abrams.com: Feature selection using neighborhood component analysis, for classification.
