[GitHub Projects Community @GithubProjects]

Building RAG systems usually means stitching together 10 different tools.

OpenRAG bundles everything into one stack.

• document ingestion
• semantic search
• agentic workflows
• chat over your data

Powered by Langflow, Docling, and OpenSearch.

Hear me out: an FFT is a linear convolutional encoder and decoder.

[Yi Ma @YiMaTweets]

I have met many students and young researchers lately who claim to be working on World Models or Embodied AI but do not even know the basics of 3D Vision or linked rigid body motions. When did we start to give students the illusion that they can *do* things right without *learning* anything right?

[Randall Balestriero @randall_balestr]

Should be "what we wish they represent" as this intuition breaks for high-dim. data https://t.co/zqQDtmZvnL + the encoded features are biased from the decoder/rec. loss https://t.co/d38rBsNZ4I. Use joint-embedding instead: https://t.co/geptacEc25 -> recovers the data coordinates
