Why would anyone build with this?

REASON 1

Reduce a dataset with thousands of features down to a simpler view that preserves key relationships.

REASON 2

Explore a high-dimensional dataset to find natural clusters and gradients you couldn't see in raw numbers.

REASON 3

Group similar data points together for clustering tasks in genomics, chemistry, or image analysis.

REASON 4

Build a foundation for tools that automatically discover structure in messy data without manual labeling.
