MODEL CONSTRUCTION SYSTEM, MODEL CONSTRUCTION APPARATUS, AND MODEL CONSTRUCTION METHOD

摘要

A model construction system, apparatus, and method are provided. The model construction system includes at least one first source apparatus, at least one second source apparatus, and a model construction apparatus. The model construction apparatus receives a de-identification data set from each first source apparatus, receives a parameter set of a source model from each second source apparatus, generates at least one aligned data set by aligning the de-identification data set according to a predetermined data format, trains an original model to an assisted training model with the aligned data set(s), generates at least one updated parameter set according to the parameter set(s) and an assisted training parameter set, updates the assisted training model with one of the updated parameter set(s), and transmits the updated parameter set(s) to the second source apparatus(es). Each second source apparatus updates the source model according to the corresponding updated parameter set.
