Title:

MULTI-TASK MODEL TRAINING METHOD, INFORMATION RECOMMENDATION METHOD, APPARATUS, AND DEVICE

Document Type and Number:

WIPO Patent Application WO/2024/040869

Kind Code:

A1

Abstract:

The present disclosure provides a multi-task model training method, relating to the technical field of artificial intelligence, and in particular, to the technical fields of deep learning, cloud computing, multi-task parallel processing, and data searching. A specific implementation solution comprises: inputting sample behavior data of a sample object into a shared sub-model, to obtain behavior characteristic information of the sample object, the behavior characteristic information comprising multiple pieces of behavior characteristic sub-information; obtaining a sub-loss value of a task processing sub-model according to the behavior characteristic sub-information associated with the task processing sub-model; determining a target gradient value corresponding to the sub-loss value, according to the sub-loss value of the task processing sub-model; determining a weight value corresponding to the sub-loss value, according to multiple target gradient values; and training a multi-task model according to multiple sub-loss values and the multiple weight values corresponding to the multiple sub-loss values. The present disclosure further provides an information recommendation method, an apparatus, an electronic device, and a storage medium.
