UMAP plot for a word2vec recommender over ~17M between tracks, albums, artists and labels. Try moving around.

i don’t really see it this way. the value of a token in Python is much higher than it is in lower-level language

i also made something like this. it cover 17M entities across tracks albums artists and labels. posted on show hn a few times but it went unnoticed (hate u (joking))

Python Parsers for NASA General Coordinate Network Notices

Hey. Needed this for a while, maybe some other hn people into astrophysics will find it useful too. It's a light package for parsing NASA GCN notices into Python data struct. Parsed notices are flat, fully typed and named so it comes easy to work with them with the autocompletion and static analyzer from your favourite IDE.
That's it, not the funniest project for sure but hope that's useful to someone.

Hello! I find these fascinating too. The 128 dimensions I mentioned are learned by the NN, they are latent space and their actual meaning is ultimately unknown. The number itself is somewhat arbitrary as it was selected optimizing memory usage vs data coverage so that the track embeddings could sit on an A100.

Hello HN,This is toposonico, a music recommender and navigable map. At core it's a skipgram word2vec model trained over ~6M playlists. Tracks are embedded in a 128d space. Embeddings for albums, artists and labels are computed marginalizing over tracks. The 2D map was built with UMAP.Both the model and UMAP were trained in the cloud over a NVIDIA A100. All things considered it cost me around...

Wrote it with the goal of publishing but realized I do not want to go through the hassle of spamming it around to get it out there. Maybe someone else will find it useful? The repo features all the stuff needed for deploying on amazon AWS EC2.
For the moment the page is reachable at:
http://ec2-16-171-47-81.eu-north-1.compute.amazonaws.com/
Note the http there, not https, I have yet to make a certificate. Hopefully hn will not kill the link. The content is made-up faker bs.
Repo is here:

Any feedback from people more experienced than me with webdev is appreciated. bests
Show HN: Misfits, a FITS table viewer for the terminal
https://github.com/peppedilillo/misfits
Hey any astrophysicist reading hn there? Was sick in august (yeah isn't that nice) and made a small python fits table viewer for the terminal with textual. It would be great to have people try it so if you find any issue I can improve it. If you have no FITS file but would like to try regardless there are some test file in `/test`. Ciao!
