Breaking the Curse of Quality Saturation with User-Centric Ranking

no code implementations24 May 2023 Zhuokai Zhao, Yang Yang, Wenyu Wang, Chihuang Liu, Yu Shi, Wenjie Hu, Haotian Zhang, Shuang Yang

A key puzzle in search, ads, and recommendation is that the ranking model can only utilize a small portion of the vastly available user interaction data.

Class-Similarity Based Label Smoothing for Confidence Calibration

no code implementations24 Jun 2020 Chihuang Liu, Joseph JaJa

The output of a neural network is a probability distribution where the scores are estimated confidences of the input belonging to the corresponding classes, and hence they represent a complete estimate of the output likelihood relative to all classes.

Feature Prioritization and Regularization Improve Standard Accuracy and Adversarial Robustness

no code implementations4 Oct 2018 Chihuang Liu, Joseph JaJa

We propose a model that employs feature prioritization by a nonlinear attention module and $L_2$ feature regularization to improve the adversarial robustness and the standard accuracy relative to adversarial training.
