BWhat changed
Added Transformer encoding of historical clicked items plus the candidate item and relative-time position features to an embedding/MLP ranker, combining the encoded sequence with user, item and context features.
Scientific scope
Added Transformer encoding of historical clicked items plus the candidate item and relative-time position features to an embedding/MLP ranker, combining the encoded sequence with user, item and context features. Specific target-aware CTR ranking integration, distinct from SASRec next-item causal prediction and BERT4Rec masked training. Reuses Wide & Deep and Transformer components. AUC, online CTR and response time are different metrics; deeper stacks were not uniformly better in the reported experiments.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
