Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

[OC] Clustering Images with OpenAI CLIP, T-SNE, UMAP & Plotly

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

Introducing the Semantic Graph
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.

Using the 80:20 rule, what top 20% of your tools, statistical tests, activities, etc. do you use to generate 80% of your results?
As with anything, it depends on the problem. But T-SNE and UMAP are often good.

I built an Image Search Engine using OpenAI CLIP and Images from Wikimedia
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

Finding correlating features in a large dataset.
Sounds like a job for UMAP https://github.com/lmcinnes/umap ?

The most perplexing bug I've ever seen
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.

Question about numpy method I found in github project
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:

Traccar VS GPS Tracker - a user suggested alternative
2 projects | 22 Dec 2023

Mobile Application that Tracks the Location of a Vehicle
I suggest traccar - https://www.traccar.org/, open source and it's already complete with a server and web interface. Now you need a gps device, one that's supported by traccar - https://www.traccar.org/devices/. I suggest getting one that's capable of making http requests because it's easier to integrate with traccar (for this you'll need a sim card with data), compared to going with an SMS route where you need a way for your server to receive SMS texts.

Any TILE or any other tracker have an alternative foss app for tracking? (just like using gadgetbridge)
Traccar I'm not as familiar with but seems like a promising vehicular oriented one https://www.traccar.org/

Ask HN: Side project of more that $2k monthly revenue what's your project?
Open source GPS tracking platform - Traccar (https://www.traccar.org/). I think picking a small B2B niche is the best way to become successful. You're not going to be super rich, but you can have a good stable lifestyle business.
- Ask HN: Small scripts, hacks and automations you're proud of?
