Existing pairwise learning algorithms do not perform well in the generality, scalability and efficiency simultaneously. To address these challenging problems, in this paper, we first analyze the relationship between the statistical accuracy and the regularized empire risk for pairwise loss. Based on the relationship, we propose a scalable and efficient adaptive doubly stochastic gradient algorithm (AdaDSG) for generalized regularized pairwise learning problems. More importantly, we prove that the overall computational cost of AdaDSG is O(<em>n</em>) to achieve the statistical accuracy on the full training set with the size of <em>n</em>, which is the best theoretical result for pairwise learning to the best of our knowledge. The experimental results on a variety of real-world datasets not only confirm the effectiveness of our AdaDSG algorithm, but also show that AdaDSG has significantly better scalability and efficiency than the existing pairwise learning algorithms.</p>}, number={01}, journal={Proceedings of the AAAI Conference on Artificial Intelligence}, author={Gu, Bin and Huo, Zhouyuan and Huang, Heng}, year={2019}, month={Jul.}, pages={3697-3704} }
