HONEYBEE: Efficient Role-based Access Control for Vector Databases via Dynamic Partitioning

Journal article Proceedings of the ACM on Management of Data · April 2, 2026 Enterprise deployments of vector databases require access control policies to protect sensitive data. These systems often implement access control through hybrid vector queries that combine nearest-neighbor search with relational predicates based o ... Full text Cite

LLM.265: Video Codecs Are Secretly Tensor Codecs

Journal article IEEE Micro · January 1, 2026 Video codecs have been refined for decades to compress visual data efficiently. This paper revisits them as general-purpose tensor codecs for large language models. LLM training and inference are increasingly limited by memory footprint and communication b ... Full text Cite

LLM.265: Video Codecs are Secretly Tensor Codecs

Conference Proceedings of the Annual International Symposium on Microarchitecture Micro · October 17, 2025 As the parameter size of large language models (LLMs) continues to expand, the need for a large memory footprint and high communication bandwidth have become significant bottlenecks for the training and inference of LLMs. To mitigate these bottlenecks, var ...
