I've seen a lot of explanations on similarity measures in vector search but this one by my colleague @dadoonet is by far the most fun! How similar* is Han Solo to: • Princess Leia: very similar • Obi-Wan: meh • Darth Vader: complete opposites Talk slides: david.pilato.fr/talks/2025/2...

What's the most underrated embedding technique you've used? Static embeddings -> speed-improvements Binary quantization -> storage-reduction Late interaction -> added granularity I'm curious about lesser-known approaches that worked surprisingly well.

Roses are red, violets are blue, A good baseline embedding model is all-MiniLM-L6-v2.

Make RAG results more trustworthy with citations. In his latest recipe, @danman966.bsky.social shows you how you can build a RAG pipeline with citations, using: - a @weaviate.bsky.social vector database and - @anthropic.com's Claude 3.5 Sonnet 📌 Code: github.com/weaviate/rec...

Normalize not knowing everything in the AI space. It's evolving fast. I’m sure your to-do list is growing as fast as mine. Here are 3 topics, I want to catch up on this quarter: • AI agents • Fine-tuning embedding models • Multimodality • (If time permits: reinforcement learning) What about you?

I’m trying to wrap my head around multi-agent system architectures. Here are some patterns I’m seeing so far: 1. Type of collaboration: Network vs. hierarchical 2. Type of information flow: Sequential vs. parallel vs. loop 3. Type of functionality: Routing vs. aggregating What else?

Some considerations for choosing a vector dimension: 1. Data complexity 2. Task complexity 3. Dataset size 4. Computational constraints 5. Performance requirements 6. Scalability requirements 7. Latency requirements What else?

#1 Rule of RAG Club: Look at your data. With the new explorer tool, looking at your data got a lot easier in Weaviate Cloud. The explorer tool provides a graphical interface to easily: • Browse collections • Inspect objects, metadata, and vectors Check it out now: https://buff.ly/3KWivSF

You can be GPU poor like me and still fine-tune an LLM. Here’s how you can fine-tune Gemma 2 in a Kaggle notebook on a single T4 GPU: • @kaggle.com offers 30 hours/week of GPUs for free • @unsloth.bsky.social uses 60% less memory to fit it on a T4 GPU 🔗Code: https://buff.ly/4apUUG2

Although I know that Vertical scaling: scaling up (to a more powerful machine) Horizontal scaling: scaling out (to multiple smaller machines) I still always have to take a second to think about it. It’s like the left-right-weakness of system design.

I talk about RAG so much, I could fill a book. So, we did - and you can download it for free. Together with my colleagues Mary & Prajjwal, we curated an e-book of the most effective advanced RAG techniques. Which ones did we miss? Get it now: weaviate.io/ebooks/advan...

Over the holidays, I learned how to fine-tune an LLM. Here’s my entry for the latest @kaggle.com comp. This tutorial shows you: • Fine-tune Gemma 2 • LoRA fine-tuning with @unsloth.bsky.social on T4 GPU • Experiment tracking with @weightsbiases.bsky.social 🔗Code: www.kaggle.com/code/iamleon...

Got myself a little early Christmas present. Although this book is from 2017, I heard so many good things about it this year. Can't wait to dig into this over the holidays. And with that being said, I hope you have some nice and relaxing holidays yourself! See you in the new year!

It’s time to review the AI space in 2024! Here’s what I got right (and what I missed) in my 2024 predictions: ✅ Evaluation ❌ Multimodal foundation models ❌ Fine-tuning open-weight models and quantization ❌ AI agents ✅ RAG lives on ❌ Knowledge graphs medium.com/towards-data...

Look what came in the mail today! This is already the 2nd edition of “Developing apps with GPT-4” by Olivier and Marie-Alice I had the pleasure to review. This edition covers the latest advancements in GPT-4, especially regarding its visual capabilities to build multimodal applications.

It's been two years since the release of ChatGPT. What cool use cases using Generative AI have you seen in the wild so far?
