Resource recall model updating method and device, electronic equipment and storage medium

The invention relates to a resource recall model updating method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining a resource click log corresponding to a current model updating period; determining a click resource pool according to the resource click log, wherein click resources represent resources clicked by a user in a time period between a current model updating period and a previous model updating period; selecting a first click resource in the click resource pool, taking the first click resource as a positive sample resource, and determining a corresponding negative sample resource from click resources except the first click resource; generating training samples in a training sample set according to the positive sample resources, the corresponding negative sample resources and a user; and optimizing parameters in the resource recall model by using a preset loss function according to the training sample set to obtain an updated resource recall model.
