Regarding the identification of elements with a high contribution rate in the inspection vector.

[screwface106]

This logic ranks the squared differences between the query vector parameters and the learned vector parameters used in Euclidean distance calculations. If this logic is customized and added to the HNSW algorithm, it could enable the calculation of the contribution of each feature to the detection of outliers.
