apt update & apt upgrade not working anymore on a Hetzer ARM VM?

Here’s the solution.

Text Embeddings: Speaking languages without learning them?

tl;dr: some *-en models perform well on other languages too.

Let’s process 1.369.841 single English XML/HTML files and index them with BAAI/bge-base-en-v1.5 embeddings for semantic search! Sounds fun? Let’s go!

A full semantic search tutorial about:

• data mining with requests and beautifulsoup
• preprocessing in pandas
• chunking the document text in smaller paragraphs of the right size for the ML model
• creating embeddings for each chunk
• calculating the mean embedding for each document
• saving data as gzipped json (small file size & easy and fast to read in js with pako.js)
• creating a static web app based on transformers.js on GitHub Pages

Let’s set up a public Zulip instance for our geospatial community! It’s live: zulip.gis.chat

Semantic search right in your browser! Calculates the embeddings and cosine similarity client-side without server-side inferencing, using transformers.js and a quantized version of sentence-transformers/all-MiniLM-L6-v2.

Create a fully working semantic search stack with only Qdrant as vector database with built-in API and transformers.js using any huggingface model as your frontend-only embedding generator. No additional inference server needed!
