Hiformer: Heterogeneous Feature Interactions Learning with Transformers for Recommender Systems

no code implementations10 Nov 2023 Huan Gui, Ruoxi Wang, Ke Yin, Long Jin, Maciej Kula, Taibai Xu, Lichan Hong, Ed H. Chi

We identify two key challenges for applying the vanilla Transformer architecture to web-scale recommender systems: (1) Transformer architecture fails to capture the heterogeneous feature interactions in the self-attention layer; (2) The serving latency of Transformer architecture might be too high to be deployed in web-scale recommender systems.

PBBFMM3D: a parallel black-box algorithm for kernel matrix-vector multiplication

3 code implementations6 Mar 2019 Ruoxi Wang, Chao Chen, Jonghyun Lee, Eric Darve

We introduce a parallel method that provably requires $O(N)$ operations to reduce the computation cost.

Block Basis Factorization for Scalable Kernel Matrix Evaluation

no code implementations3 May 2015 Ruoxi Wang, Yingzhou Li, Michael W. Mahoney, Eric Darve

Kernel methods are widespread in machine learning; however, they are limited by the quadratic complexity of the construction, application, and storage of kernel matrices.
