Today we announced $13.6M in funding and launched the first Control Plane for Agentic AI — giving companies a way to control their AI workforce. Now, see how it works. 👇 #AIGovernance #SeedFunding
Just a really great thread about the limits of LLMs

Is Cosine-Similarity of Embeddings Really About Similarity? Netflix cautions against blindly using cosine similarity as a measure of semantic similarity between learned embeddings, as it can yield arbitrary and meaningless results. 📝arxiv.org/abs/2403.05440

Extended Mind Transformers (EMTs) are a new approach to working with very large contexts and external data sources developed by @KlettPhoebe, @thomasahle, Normal's AI team. Inspired by the Extended Mind Thesis, we modify Multihead Attention to directly query a vector database.
This is why you severely limit yourself by optimizing for precision. Use the user to get the precision, use the compute to get the recall

Previously we've seen how to improve retrieval by funetuning an embedding model. @llama_index also supports finetuning an adapter on top of existing models, which lets us improve retrieval without updating our existing embeddings. 🚀 Let's see how it works 👇🧵

We report a model that can go from natural language instructions, to robot actions, to synthesized molecule with an LLM. We synthesized catalysts, a novel dye, and insect repellent from 1-2 sentence instructions. This has been a seemingly unreachable goal for years! 1/3
"semantic embeddings" are becoming increasingly popular, but "semantics" is really ill-defined. sometimes you want to search for text given a description of its content. current embedders suck at this. in this work we introduce a new embedder. @ravfogel @valentina__py @AvshalomM

Clever paper — HyDE: Hypothetical Document Embeddings Instead of encoding the user's query to retrieve relevant documents, generate a "hypothetical" answer and encode that. Documents with right answers more similar to wrong answers than to questions. arxiv.org/abs/2212.10496
