Large codebooks and frequent table lookups consume memory bandwidth, and implicit-codebook alternatives depend on costly transforms such as Hadamard rotations. The authors propose SCVQ, a post-training… ## Co-authors here 2 co-authors with a page, the most papers together first. - [Zhaofeng He](https://md.research.elamur.ai/free/en/authors/zhaofeng-he/) ×2 - [Zixuan Zhou](https://md.research.elamur.ai/free/en/authors/zixuan-zhou/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/) ×2: [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) ×2 Updated 2 November 2026
