Huh, generally whenever I saw the lookup table approach in literature it was also referred to as quantization, guess they wanted to disambiguate the two methods

Though I'm not sure how warranted it really is, in both cases it's still pretty much the same idea of reducing the precision, just with different implementations

Edit: they even refer to it as LUT quantization on another page: https://apple.github.io/coremltools/docs-guides/source/quant...

Just "quantization" is poor wording for that. Quantization means dropping the low bits.

Sounds like it was confused with "vector quantization" which does involve lookup tables (codebooks). But "palletization" is fine too.
