FAQPage Schema
How do I reduce high-dimensional data for 2D visualization?▼

Dimensionality reduction for 2D visualization is achieved by applying UMAP to standardize high-dimensional image, text, or tabular data. This generates scalable, meaningful low-dimensional representations suitable for exploratory data analysis.

Can I use UMAP for preprocessing before density-based clustering?▼

Yes, UMAP works as a preprocessing step for density-based clustering workflows like HDBSCAN. It transforms complex high-dimensional data into a lower-dimensional space where clustering algorithms can identify meaningful groups more effectively.

Does this dimensionality reduction approach support supervised learning workflows?▼

UMAP supports supervised dimensionality reduction workflows alongside its unsupervised capabilities. It uses an sklearn-like API with fit and transform methods, allowing you to train embeddings that leverage labeled data for optimized projections.

How do I align embeddings from multiple datasets for comparison?▼

Multi-dataset comparison is handled using AlignedUMAP. This feature aligns embeddings across different datasets, allowing you to track structural changes and compare high-dimensional relationships consistently across varying data slices.

What is Parametric UMAP and how does it work for embeddings?▼

Parametric UMAP implements embeddings using a trainable neural network model instead of a fixed graph. It provides the same low-dimensional representations while allowing you to save, load, and apply the trained model to transform new, unseen data.

Are there limitations when reducing high-dimensional data with UMAP?▼

UMAP requires standardized input data to generate accurate low-dimensional representations. While it offers inverse_transform capabilities to map back to the original space, this reconstruction is approximate and may not perfectly recover the initial high-dimensional features.
