Logitech forgot to renew its server certificate, so now my mouse scrolls in the opposite direction, and I'm unable to move between windows. What a time to be alive.

A read that resonates. I keep coming back to the thought of how curation by algorithms fits into this idea of the web. If someone has some good reads on this, let me know! The group at serendipityengine.be is one great example imo.

Let’s collaborate on democratizing insights from tabular data in Amsterdam! ✨

PhD directions: 1) fundamental techniques for tabular foundation models, 2) reliable mechanisms for AI-powered tabular data analysis.

Sharing w/ friends appreciated! ⬇️

The winner is '.translatesAutoresizingMaskIntoConstraints', with 42 characters in a single token. OpenAI really values iOS development I guess πŸ˜…

As it turns out: It's one of the longest tokens without special characters. When considering special characters, the top ones look like this.

Today's funny tokenization realization: The GPT4 tokenizer has 1 single token for the entire lower- and uppercase alphabet.

I'll get straight to the point.

We trained 2 new models. Like BERT, but modern. ModernBERT.

Not some hypey GenAI thing, but a proper workhorse model, for retrieval, classification, etc. Real practical stuff.

It's much faster, more accurate, longer context, and more useful. 🧡

Yesterday @ellisamsterdam.bsky.social hosted the yearly NeurIPS-Fest, a pre-party for NeurIPS with a keynote talk, poster session, drinks and bites! 🍺🍻

The keynote was by @canaesseth.bsky.social , who talked about "Diffusion, Flows and other stories", presenting his 5 papers accepted at NeurIPS! πŸ’₯

I'm looking for a textbook to take me through fundamental ML concepts again. Not too applied, and preferably with a Deep Learning angle. Currently considering the new Deep Learning book by Bishop, but maybe my Bluesky following has different recommendations. Let me know :)

As people are slowly moving over, I thought I'd make a list of people on here who work on IR & RecSys in Amsterdam. Who am I missing? Both researchers and engineers :)
