FAQPage Schema
How do I reduce high-dimensional data for visualization?

To reduce high-dimensional data for visualization, you can apply UMAP to fit a fast, scalable 2D or 3D embedding. This transforms complex datasets into low-dimensional representations suitable for visualizing relationships and downstream machine learning pipelines.

What is the best way to preprocess data for clustering?

The best way to preprocess data for clustering is using dimensionality reduction to create low-dimensional embeddings. UMAP provides fast, scalable embeddings that effectively prepare high-dimensional data for clustering algorithms like HDBSCAN.

Can I use UMAP embeddings in sklearn machine learning pipelines?

Yes, you can use UMAP embeddings in sklearn machine learning pipelines. UMAP supports standard sklearn conventions, includes transform and inverse_transform methods, and integrates seamlessly into feature engineering workflows for downstream models.

Does parametric UMAP support supervised embeddings?

Parametric UMAP supports supervised and semi-supervised embeddings. It extends standard manifold learning by allowing you to guide the embedding process with labels, providing advanced options for diverse datasets and specific downstream ML tasks.

When should I use UMAP over other dimensionality reduction tools?

You should use UMAP over other dimensionality reduction tools when you need fast, scalable embeddings for large, high-dimensional datasets. It is particularly effective for biological data visualization and generating features for downstream ML models.
