Dear all,
Welcome to next VSAONLINE webinar.
On Monday October 7th at 20:00 GMT Thomas D. Ahle from Meta Research, IT University of Copenhagen, BARC
will give a talk “Clustering the Sketch: Dynamic Compression for Embedding Tables”.
Date: October
7, 2024
Time: 20:00 GMT

Abstract: Embedding tables are used by machine learning systems to work with categorical features. In modern Recommendation Systems, these tables can be very large, necessitating the development of new methods for fitting them in memory, even during training. We suggest Clustered Compositional Embeddings (CCE) which combines clustering-based compression like quantization to codebooks with dynamic methods like The Hashing Trick and Compositional Embeddings (Shi et al., 2020). Experimentally CCE achieves the best of both worlds: The high compression rate of codebook-based quantization, but *dynamically* like hashing-based methods, so it can be used during training. Theoretically, we prove that CCE is guaranteed to converge to the optimal codebook and give a tight bound for the number of iterations required.
Welcome,
Evgeny
