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.
