> MADDNESS

I think this name really fits well to the concept. Replacing matrix-multiplication with some hash-lookups! (warning: an overly simplified statement)

This is a really interesting application of PQ(product quantization), which itself also requires learning (usually K-means). Paper: https://lear.inrialpes.fr/pubs/2011/JDS11/jegou_searching_wi...

Considering that ANN has survived through many approximations (e.g. lower precision, pruning), and that many ANN applications are anyway subjective (e.g. image processing, recommendation), I think this can be highly useful in many cases.

Certainly off topic, but gotta say I prefer “MADDLESS” over “MADDNESS” for being more… obvious. It still sounds close enough to me, but again I might be just letting my Southern-Chinese ear loose with the n/l confusions…
