Hi,
how exactly should we handle the transformation of query vectors ?
I can transform the database vectors and train the index offline, but when I receive queries, should I multiply the queries by the inverse L of the database vectors or should I transform the queries separately with their own inverse Cholesky decomposition of their covariance matrix ?
Thanks.
