Is data standardization necessary before using this skill?

Standardization is critical. You should always scale features to comparable ranges before applying UMAP to ensure all dimensions are weighted equally.

How does UMAP compare to t-SNE for AI tasks?

UMAP is generally faster than t-SNE, preserves more global structure, and offers better scalability, making it ideal for large-scale AI agent data analysis.

What is Parametric UMAP?

Parametric UMAP uses neural networks to learn the mapping function, allowing for efficient transformation of new data and integration with deep learning architectures.

Can I use UMAP for supervised learning?

Yes, UMAP supports both supervised and semi-supervised dimension reduction by incorporating label information during the fitting process to guide the embedding.

What are the core parameters to tune in UMAP?

The primary parameters are n_neighbors (local vs. global balance), min_dist (cluster density), n_components (output dimensions), and metric (distance calculation).
