What is the primary advantage of UMAP over t-SNE?

UMAP is generally faster, scales more efficiently to large datasets, and preserves a better balance of local and global topological structures.

How should I tune UMAP for clustering purposes?

For clustering (like HDBSCAN), it is recommended to increase n_neighbors to around 30, set min_dist to 0.0, and use a higher n_components value (5-10) to preserve density.

Does this skill support supervised learning?

Yes, UMAP can incorporate target labels during the fitting process to create embeddings that emphasize class separation while maintaining internal structure.

Can UMAP handle new data points after training?

Yes, UMAP provides a transform() method that allows you to project new data into the existing embedding space without retraining the entire model.

소개

The UMAP-Learn skill integrates the Uniform Manifold Approximation and Projection algorithm into Claude's workflow, providing a powerful tool for analyzing high-dimensional datasets. It excels at preserving both local and global structures within data, making it superior to t-SNE for many visualization and preprocessing tasks. This skill enables Claude to guide you through complex tasks such as 2D/3D data visualization, supervised metric learning, and preprocessing for density-based clustering (HDBSCAN), while offering specific guidance on parameter tuning for n_neighbors, min_dist, and metric selection.
