Implement one or both of processing of computer queries using machine learning models and/or generation of machine learning models in a computer system. A computer processor generates a plurality of stored machine learning models. A computer processor extracts a plurality of updated parameters sets from the plurality of stored machine learning models. A computer processor creates a new machine learning model based on the respective distribution of each parameter included in the plurality of updated parameters sets. A computer processor processes at least one new query using the new machine learning model.
