Large-Scale Visual Search with Binary Distributed Graph at Alibaba

Kang Zhao, Pan Pan, Yun Zheng, Yanhao Zhang, Changxu Wang, Yingya Zhang, Yinghui Xu, Rong Jin
2019 Proceedings of the 28th ACM International Conference on Information and Knowledge Management - CIKM '19  
For a deployed visual search system with several billions of online images in total, building a billion-scale offline graph in hours is essential, which is almost unachievable by most existing methods.  ...  In this paper, we propose a novel algorithm called Binary Distributed Graph to solve this problem.  ...  At Alibaba, a typical scenario of ANNS is visual search. It has been studied for many years, and gives birth to a successful intelligence E-commercial application named "Pailitao".  ...

Neuron-level Structured Pruning using Polarization Regularizer

Tao Zhuang, Zhixuan Zhang, Yuheng Huang, Xiaoyi Zeng, Kai Shuang, Xiang Li
2020 Neural Information Processing Systems  
A more reasonable pruning method is to only suppress unimportant neurons (with 0 scaling factors), and simultaneously keep important neurons intact (with larger scaling factor).  ...  The reasoning is that neurons with smaller scaling factors have weaker influence on network output. A scaling factor close to 0 actually suppresses a neuron.  ...  Acknowledgments and Disclosure of Funding This work is supported by Alibaba Group. The authors would like to thank the Search and Recommendation Division of Alibaba Group for support of this work.  ...
