Fisher linear discriminant analysis 深度学习
WebLDA is the direct extension of Fisher's idea on situation of any number of classes and uses matrix algebra devices (such as eigendecomposition) to compute it. So, the term "Fisher's Discriminant Analysis" can be seen as obsolete today. "Linear Discriminant analysis" should be used instead. See also. WebJan 3, 2024 · Some key takeaways from this piece. Fisher’s Linear Discriminant, in essence, is a technique for dimensionality reduction, not a discriminant. For binary classification, we can find an optimal threshold …

WebLinear and quadratic discriminant analysis are the two varieties of a statistical technique known as discriminant analysis. #1 – Linear Discriminant Analysis Often known as LDA, is a supervised approach that attempts to predict the class of the Dependent Variable by utilizing the linear combination of the Independent Variables.
