To head this off, this implementation is not an evolution of RabitQ in any way. It's intellectually dishonest to say it's an evolution of RaBitQ. I know that's pedantic, but it's a fact. This is the next step of the global vector quantization optimization done already in Lucene. Instead of global, it's local and utilizes anisotropic quantization. I am still curious as to what in particular is considered built on RaBitQ here. Just because things reach the same ends (various bit level quantization) doesn't mean they are the same. We can say "so this idea is unique from RaBitQ in these ways" to keep attribution, but it seems weird to call out another algorithm to simply say this one is different. I agree, Elastic stuff should be discussed and fixed in a different forum. -- This is an automated message from the Apache Git Service.
