Beyond Centralization: User-Controlled Federated Recommendations in Practice

Collection of recent arXiv papers (May 14, 2026) covering advances in recommender systems, retrieval, and web-enabled LLM agents. Key themes: user-controlled, privacy-preserving federated recommendations deployed live; MLP-based distillation (SID-MLP) to accelerate generative recommenders; ecosystem-level manipulation/optimization of web evidence for LLM search agents (EcoGEO/TRACE); context-dependent image meaning and retrieval; LLM-driven query-aware dynamic content expiration (industrial deployment at Baidu); standardized reproducibility evaluation for conversational recommenders (ReDial);检
