What problem does it solve?

UMAP-Learn helps you turn high-dimensional data into compact, meaningful embeddings so you can visualize structure, compare samples, and prepare features without losing important relationships.

Core Features & Use Cases

  • Nonlinear dimensionality reduction: Create 2D or 3D embeddings that preserve local and global structure better than many linear projections.
  • Supervised and semi-supervised workflows: Guide embeddings with labels when you need clearer class separation or partially labeled datasets.
  • Advanced embedding variants: Use DensMAP for density preservation, AlignedUMAP for related time-series or batch datasets, and Parametric UMAP for learned transforms on new data.
  • Practical use case: Apply it to clustered customer behavior, document vectors, image features, or experimental measurements to reveal hidden patterns and prepare data for downstream modeling.

Quick Start

Use the umap-learn skill to embed my dataset into two dimensions with metric-aware preprocessing and reproducible settings.

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

You can reduce high-dimensional data using UMAP to project it into 2D or 3D embeddings for visualization and clustering. This preserves local and global structure better than linear methods across numeric, text, and temporal datasets.

Can I use UMAP for supervised or semi-supervised embeddings?

UMAP supports supervised and semi-supervised workflows by using labels to guide the embedding process. This yields clearer class separation for fully or partially labeled datasets.

What is the best way to embed related time-series datasets consistently?

AlignedUMAP is designed for embedding related time-series or batch datasets consistently. It aligns embeddings across multiple datasets to maintain comparable structures over time or between batches.

Does UMAP integrate with sklearn pipelines and transformations?

UMAP provides sklearn-compatible fit, transform, and inverse_transform methods for seamless pipeline integration. It requires metric-aware preprocessing and reproducible random_state control for reliable execution.

How does Parametric UMAP work for transforming new data?

Parametric UMAP learns a transform function that can be applied to project new, unseen data. This allows you to map incoming data points into the existing low-dimensional embedding space without retraining.

When should I use DensMAP instead of standard UMAP?

Use DensMAP instead of standard UMAP when your analysis requires preserving the local density of data points in the low-dimensional embedding. This helps accurately represent clusters with varying densities.
