UMAP Dimension Reduction, Main Ideas!!!
Показать описание
UMAP is one of the most popular dimension-reductions algorithms and this StatQuest walks you through UMAP, one step at a time, so that you will have a solid understanding of how UMAP works.
NOTE: This StatQuest is based on the original UMAP manuscript...
...specifically Appendix C, From t-SNE to UMAP, which is also here...
...and the UMAP user documentation...
For a complete index of all the StatQuest videos, check out...
...or...
If you'd like to support StatQuest, please consider...
Buying my book, The StatQuest Illustrated Guide to Machine Learning:
...or...
...a cool StatQuest t-shirt or sweatshirt:
...buying one or two of my songs (or go large and get a whole album!)
...or just donating to StatQuest!
Lastly, if you want to keep up with me as I research and create new StatQuests, follow me on twitter:
0:00 Awesome song and introduction
1:07 Motivation for UMAP
2:55 UMAP main ideas
5:22 Calculating high-dimensional similarity scores
10:41 Getting started with the low-dimensional graph
12:37 Calculating low-dimensional similarity scores and moving points
15:49 UMAP vs t-SNE
