FAQPage Schema
What is dimensionality reduction for high-dimensional data visualization?▼

Dimensionality reduction transforms high-dimensional numerical datasets into lower-dimensional embeddings, preserving local and global structure to enable clearer 2D or 3D data visualization and exploration.

How do I reduce high-dimensional embeddings for clustering preprocessing?▼

You can apply dimensionality reduction to generate lower-dimensional embeddings, which serve as effective preprocessing for clustering algorithms like HDBSCAN to identify density-based clusters in large-scale datasets.

Can I use UMAP embeddings in sklearn-compatible machine-learning pipelines?▼

Yes, UMAP supports sklearn-compatible pipelines with tunable parameters like n_neighbors, min_dist, and n_components, allowing embeddings to be integrated directly as feature engineering steps in machine-learning models.

Does UMAP support supervised and semi-supervised dimensionality reduction?▼

Yes, UMAP supports supervised and semi-supervised embeddings, as well as Parametric UMAP, enabling efficient transformation of new data for downstream analysis across biology, chemistry, and text datasets.

What are the limitations of nonlinear embeddings for machine-learning feature engineering?▼

Nonlinear embeddings require careful tuning of parameters like n_neighbors and min_dist to balance local versus global structure preservation, and transformed embeddings may not always capture complex topological relationships perfectly.
