Somewhat related: a book that really helped me is Picturing Quantum Processes by Bob Coecke. It's a visual representation of quantum processes, which really helped me understand the concept

"Kamer 306 is a 2006 documentary about the birth of electronic music inside the Philips Natuurkundig Laboratorium (NatLab) in Eindhoven. Set in the legendary Room 306 of the lab’s Acoustics Department, the film traces how Philips technicians, engineers, and composers opened up a completely new sonic world in the late 1950s."

New comment by bobvanluijt in "Hybrid Search vs. Agentic Search Benchmarks"

bobvanluijt — Wed, 24 Sep 2025 12:48:16 +0000

Besides pure vector search there is hybrid (BM25 + vector) but now there is also agentic search (where the agent can set additional filters, do multiple roundtrips, etc on top of hybrid vector search.

Meet Elysia - a decision tree based agentic system that dynamically displays data, learns from user feedback, and chunks documents on-demand.

Most AI chatbots are stuck in a text-in, text-out world. But what if your AI could dynamically decide not just what to say, but ? Elysia is designed to completely rethink how we interact with data through AI.

It depends on additional filters and whether you want to use vector search only. The upside of using Faiss would be storing the ID as file metadata and embedding it in the Faiss index. However, if you need any other filters or data, you would need to store it somewhere else.

How nice to see Stockhausen on the front page. It’s definitely an acquired taste, but if you take the time to dive in, you will appreciate it
