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.
