Abstract
An alternating least square recommendation method, system, and non-transitory computer readable medium, include partially updating a user's feature when an update ratio is less than a pre-defined threshold ratio, the pre-defined threshold ratio being configurable based on a preference of an existing sparse matrix factorization, where the pre-defined threshold ratio is pre-defined by setting the pre-defined threshold ratio to variable values according to a past acceptable update.
