WebAug 15, 2024 · Regularized Discriminant Analysis (RDA): Introduces regularization into the estimate of the variance (actually covariance), moderating the influence of different variables on LDA. The original development was called the Linear Discriminant or Fisher’s Discriminant Analysis.

Webitem. The most discriminant attribute is assigned by the highest Fisher score. Thus by sorting attributes according to their Fisher scores, a number of most discriminant attributes contribute a good feature vector for recognition, e.g., the use of nearest neighbor under Euclidean distance as a classifier. The number of most discriminant ... The terms Fisher's linear discriminant and LDA are often used interchangeably, although Fisher's original article actually describes a slightly different discriminant, which does not make some of the assumptions of LDA such as normally distributed classes or equal class covariances.
