Web7 apr. 2024 · 线性判别分析（Linear Discriminant Analysis，简称LDA）是一种经典的监督学习的数据降维方法。 LDA 的主要思想是将一个高维空间中的数据投影到一个较低维的空间中，且投影后要保证各个类别的类内方差小而类间均值差别大，本文主要以推导数学公式为主，从算法的物理意义出发，然后一步一步推导得到 ... WebOver the past decades, there has been an increase of attention to adapting machine learning methods to fully exploit the higher order structure of tensorial data. One problem of great interest is tensor classification, and in particular the extension of linear discriminant analysis to the multilinear setting. We propose a novel method for multilinear …
WebSparse Linear Discriminant Analysis Linear discriminant analysis is a standard tool for classi cation of observations into one of two or more groups. Further, the data can be visualized along the obtained discriminative directions. As with principal component analysis, these directions are combinations of all predictor variables. WebWe can divide the process of Linear Discriminant Analysis into 5 steps as follows: Step 1 - Computing the within-class and between-class scatter matrices. Step 2 - Computing the eigenvectors and their corresponding eigenvalues for the scatter matrices. Step 3 - Sorting the eigenvalues and selecting the top k.
