ECHO: Efficient Cascade with Homogeneous Operators for Distillation-Guided 100K-Sequence Modeling

arXiv:2610.28569v1 Announce Type: new Abstract: Modeling lifetime user behavior sequences is essential for capturing long-range preferences in industrial recommendation, yet 100K-length user sequences make target-aware…

Neighborhood-Aware Unlearning for Generative Recommendation

arXiv:2610.27232v1 Announce Type: new Abstract: Generative recommendation predicts items by autoregressively generating semantic identifiers (SIDs), whose tokens are shared across semantically related items. With this…

Evolving Semantic Indexes for Generative Retrieval

arXiv:2610.28568v1 Announce Type: cross Abstract: Generative retrieval (GR) casts search and recommendation as autoregressive generation of discrete semantic identifiers (SIDs). SID design largely determines GR quality,…

Multimodal Reranking Is a System One Decision

arXiv:2610.28435v1 Announce Type: new Abstract: Multimodal rerankers are usually dedicated models: a vision-language model (VLM) is trained on retrieval data to score the candidates of a query. Scoring options is not…

GARRET: Generative Feedback for Region Retrieval in Visual Documents

arXiv:2610.27829v1 Announce Type: cross Abstract: Multimodal retrieval-augmented generation over visually rich documents requires evidence at a finer granularity than entire pages. Existing visual retrievers typically…

MOSS: A Production Framework for Monitoring and Diagnosing Semantic Failures in Search and Recommendation Systems

arXiv:2610.26902v1 Announce Type: new Abstract: Detecting semantic failures in production recommendation and search systems is hard: behavioral metrics lag by days, manual review does not scale, and most LLM evaluation…

The Bottleneck Is Retrieval, Not Reading: Diagnosing Evidence-Based Generation with RAG for Long Context Question Answering

arXiv:2610.26951v1 Announce Type: cross Abstract: Retrieval-augmented generation (RAG) is the dominant paradigm for grounding large language models in external corpora, but its similarity-driven, chunked pipeline has…
