Practice with Graph-based ANN Algorithms on Sparse Data: Chi-square Two-tower model, HNSW, Sign Cauchy Projections

no code implementations13 Jun 2023 Ping Li, Weijie Zhao, Chao Wang, Qi Xia, Alice Wu, Lijun Peng

In this paper, we report our exploration of efficient search in sparse data with graph-based ANN algorithms (e. g., HNSW, or SONG which is the GPU version of HNSW), which are popular in industrial practice, e. g., search and ads (advertising).

Object-Based Image Coding: A Learning-Driven Revisit

no code implementations18 Mar 2020 Qi Xia, Haojie Liu, Zhan Ma

The Object-Based Image Coding (OBIC) that was extensively studied about two decades ago, promised a vast application perspective for both ultra-low bitrate communication and high-level semantical content understanding, but it had rarely been used due to the inefficient compact representation of object with arbitrary shape.

A new perspective in understanding of Adam-Type algorithms and beyond

no code implementations25 Sep 2019 Zeyi Tao, Qi Xia, Qun Li

Moreover, we provide new variant of Adam-Type algorithm, namely AdamAL which can naturally mitigate the non-convergence issue of Adam and improve its performance.
