Claim 2:
3. The method according to claim 2, wherein the implicit feedback information comprises a click history sequence and an unclick history sequence corresponding to the target object, and the explicit feedback information comprises an explicit feedback history sequence corresponding to the target object; and
the respectively inputting the explicit feedback information and the implicit feedback information into the deep feedback interaction component, and obtaining the behavior preference information of the target object outputted by the deep feedback interaction component further comprises:
respectively inputting the click history sequence, the unclick history sequence, and the explicit feedback history sequence corresponding to the target object into the deep feedback interaction component, and performing encoding and decoding processing on the click history sequence, the unclick history sequence, and the explicit feedback history sequence based on a transformer based on a self-attention mechanism in the deep feedback interaction component to obtain a corresponding high-order click vector, a corresponding high-order unclick vector, and a corresponding explicit feedback high-order vector;
performing feature interaction on the high-order click vector and the unclick history sequence using an attention mechanism, to obtain a first interaction vector corresponding to the target object, and performing feature interaction on the explicit feedback high-order vector and the unclick history sequence to obtain a second interaction vector corresponding to the target object; and
concatenating the high-order click vector, the high-order unclick vector, the explicit feedback high-order vector, the first interaction vector, and the second interaction vector to obtain a behavior preference feature vector of the target object, and using the behavior preference feature vector as the behavior preference information of the target object.
