WebNov 7, 2024 · PCA helps to assess which original samples are similar and different from each other. PCA preserves the global data structure by forming well-separated clusters but can fail to preserve the similarities within the clusters. PCA works better in revealing linear patterns in high-dimensional data but has limitations with the nonlinear dataset. WebThe same result can be accomplished via so called Fisher linear classification functions which utilizes original features directly. However, Bayes' approach based on discriminants is a little bit general in that it will allow to use separate class discriminant covariance matrices too, in addition to the default way to use one, the pooled one.
