ADAPTING AI MODELS FROM ONE DOMAIN TO ANOTHER

摘要

A method for adapting to a new domain an AI model pre-trained for a current domain. Having at least one main block of the AI model for modeling a target variable and having at least one covariates block of the AI model for modeling covariates effect on the target variable in the current domain, the method comprises: replacing the covariates block with a new covariates block adapted to the new domain, the new covariates block modifying one or more first layers compared to the covariate block, the target variable in the new domain being affected differently by at least one of the one or more covariates; training the new covariates block of the AI model using a new-domain-specific dataset from the new domain; and fine-tuning the at least one main block of the AI model using the new-domain-specific dataset from the new domain.
