Both the viz, and that the 2D UMAP projection is actually enough to get accurately delineated topics.
Hence why I think the typical embedding dimensionality is way way too high.
- markisus 3y agoDo you think 1D could work? Maybe topic-space is some sort of tree-shaped structure where documents live in the thin strands.
- minimaxir 3y ago1D could work on certain datasets but it wouldn't be ideal.
- adammarples 3y agoWhy not just embed directly to 2d? Does it give worse results than UMAP?
