SITA: Semantic Interest Tokens for Target-Aware Compression in Long-Sequence Recommendation

SITA enables target-aware compression by organizing compressed interests into semantic structures through semantic identifiers learned via parallel semantic quantization, conditioned on the semantic identifier of the target item, and adaptively aggregates the corresponding structured interests to construct the target-s...

Rethinking Item Tokenization in Generative Recommenders: From Fixed Atoms to Semantic Subwords

Semantic Subword Tokenization (SST) is proposed, which represents historical items as variable-length semantic subwords while preserving fixed-length target decoding and introduces Behavior-induced Co-occurrence Augmentation to inject coarse-grained semantic prefix transition signals.

Accurate KV Cache Eviction via Anchor Direction Projection for Efficient LLM Inference

A novel method, namely AnDPro, is proposed, which introduces a projection-based scoring function to more accurately measure token importance and guide more accurate token selection in key-Value cache eviction.
