ML tooling beyond LLMs (stub)

Many practical "AI" systems are classic ML + efficient retrieval and matching - not only chatbots.

• Vector similarity search (embeddings): FAISS
• Classic vision matching: SIFT (Lowe, 2004); ORB (Rublee et al., 2011)
• Music fingerprinting: Wang, 2003 (Shazam)
• Audio - pitch tracking: CREPE
• Audio to MIDI (piano transcription): Onsets and Frames
