There was a problem hiding this comment.
According to what I understand, this is not Quantization, this is Pruning or maybe Whitening. Correct me if I'm wrong, but this drop_during_build_ indicates whether a threshold is used for removing small values.

changed to IsApproximated. wanted to express whether the index is accurate kNN or ANN so not choosing a name that reflects how we do the approximation.
