Clustering and Dimensionality Reduction: Understanding …
WebIt is highly recommended to use another dimensionality reduction method (e.g. PCA for dense data or TruncatedSVD for sparse data) to reduce the number of dimensions to a reasonable amount (e.g. 50) if the number of features is very high. This will suppress some noise and speed up the computation of pairwise distances between samples. WebAug 6, 2024 · In this Notebook, we will explore a cool new dimensionality reduction technique called Uniform Manifold Approximation and Projection (UMAP) and check its applicability for doing supervised clustering and embedding over the similarity space computed from the leaves of a random forest..
