Dimensionality Reduction Techniques ML Frameworks

Implementations and tutorials of linear and non-linear dimensionality reduction algorithms (PCA, LDA, SVD, autoencoders, etc.) applied to datasets and images. Does NOT include general feature engineering, feature selection, or domain-specific applications that merely use dimensionality reduction as a preprocessing step.

There are 18 dimensionality reduction techniques frameworks tracked. 1 score above 50 (established tier). The highest-rated is beringresearch/ivis at 58/100 with 343 stars and 1,087 monthly downloads.
