Bayesian Supervised Hashing

no code implementations CVPR 2017 Zihao Hu, Junxuan Chen, Hongtao Lu, Tongzhen Zhang

To address this problem, we present a novel fully Bayesian treatment for supervised hashing problem, named Bayesian Supervised Hashing (BSH), in which hyperparameters are automatically tuned during optimization.

Deep CTR Prediction in Display Advertising

no code implementations20 Sep 2016 Junxuan Chen, Baigui Sun, Hao Li, Hongtao Lu, Xian-Sheng Hua

Click through rate (CTR) prediction of image ads is the core task of online display advertising systems, and logistic regression (LR) has been frequently applied as the prediction model.

Adaptive Affinity Matrix for Unsupervised Metric Learning

no code implementations13 Nov 2015 Yaoyi Li, Junxuan Chen, Hongtao Lu

In this paper, we propose a novel method, dubbed Adaptive Affinity Matrix (AdaAM), to learn an adaptive affinity matrix and derive a distance metric from the affinity.
