umap VS mapbox-gl-js

UMAP GitHub repository: https://github.com/lmcinnes/umap

Uniform Manifold Approximation and Projection (UMAP) is a well-known dimensionality reduction method along with t-SNE.

A number of excellent topic modeling libraries exist in Python today. BERTopic and Top2Vec are two of the most popular. Both use sentence-transformers to encode data into vectors, UMAP for dimensionality reduction and HDBSCAN to cluster nodes.

As with anything, it depends on the problem. But T-SNE and UMAP are often good.

I used for this project Flask and OpenAI CLIP. For the vector search I used approximate nearest neighbors provided by spotify/annoy. I used Flask-SQLAlchemy with GeoAlchemy2 to query GPS coordinates. The embedding was done using UMAP.

side note: instead of t-SNE consider UMAP - provides better results (and it's much faster) https://github.com/lmcinnes/umap

Sounds like a job for UMAP https://github.com/lmcinnes/umap ?

I am a fairly experienced python developer/researcher (about 10 years), and have found a bug that breaks all of my intuitions. I am messing with the [UMAP](https://github.com/lmcinnes/umap) repository and trying to add the option to disable some additional features. I've stripped everything from it but have a [quick test that will run my UMAP version and compare the outputs with what the original gave](https://github.com/Andrew-Draganov/probabilistic_dim_reduction/blob/master/umap/nndescent_umap_test.py). Managing my random seeds, same inputs, all that.

I'm currently reading through a project on github, https://github.com/lmcinnes/umap, and in `umap/umap_.py` at line 2287, they have this:

Good. Brave's fiddling with WebGL causes >50% of my bug reports from 1% of users.

Laravel and Mapbox GL JS

It originated as an open-source fork of Mapbox-gl-js before they switched to a non-open-source license on 8th December 2020.

Do you have programming skills? MapboxGL JS is a great library for stuff like this, you can really easily add a layer of GeoJSON data to a map. If you're looking for something less technical Google map lets you create custom maps where you can add a bunch of pins.

From the latest commits (not released/stable yet): git clone https://github.com/mapbox/mapbox-gl-js.git yarn install yarn run build-prod-min yarn run build-css Then use the generated mapbox-gl.js and mapbox-gl.css files. See CONTRIBUTING.md for more details.

> too bad it doesn't come with some code

Mapbox changed the license of their code last year I think to a proprietary one. https://github.com/mapbox/mapbox-gl-js/blob/main/LICENSE.txt

It requires a mapbox user license with billing enabled to use this code, let alone make modifications. But the source is viewable on github.

The software stopped being open source from v2 onwards. The new licence makes it merely shared source.

This GitHub issue where this change is announced provides a number of more in-depth explanations why this is a bad thing for most users of the software: https://github.com/mapbox/mapbox-gl-js/issues/10162

It's a bummer mapbox isn't open source anymore, now you're (and lots of other peoplare) are stuck pre-2.0.0 :(
