Cross-Age Face Verification by Coordinating With Cross-Face Age Verification

no code implementations CVPR 2015 Liang Du, Haibin Ling

As shown in our experiments, the algorithm effectively balances feature sharing and feature exclusion between the two tasks; and, for face verification, the algorithm effectively removes distracting features used in age verification.

Visualization of Multi-Objective Switched Reluctance Machine Optimization at Multiple Operating Conditions with t-SNE

no code implementations4 Nov 2019 Shen Zhang, Shibo Zhang, Sufei Li, Liang Du, Thomas G. Habetler

However, the number of objectives that would need to be optimized would significantly increase with the number of operating points considered in the optimization, thus posting a potential problem in regards to the visualization techniques currently in use, such as in the scatter plots of Pareto fronts, the parallel coordinates, and in the principal component analysis (PCA), inhibiting their ability to provide machine designers with intuitive and informative visualizations of all of the design candidates and their ability to pick a few for further fine-tuning with performance verification.

A Data-Driven Democratized Control Architecture for Regional Transmission Operators

no code implementations20 Sep 2021 Xiaoyuan Fan, Daniel Moscovitz, Liang Du, Walid Saad

As probably the most complicated and critical infrastructure system, U. S. power grids become increasingly vulnerable to extreme events such as cyber-attacks and severe weather, as well as higher DER penetrations and growing information mismatch among system operators, utilities (transmission or generation owners), and end-users.

DELTA: Dynamic Embedding Learning with Truncated Conscious Attention for CTR Prediction

no code implementations3 May 2023 Chen Zhu, Liang Du, Hong Chen, Shuang Zhao, Zixun Sun, Xin Wang, Wenwu Zhu

To tackle this problem, inspired by the Global Workspace Theory in conscious processing, which posits that only a specific subset of the product features are pertinent while the rest can be noisy and even detrimental to human-click behaviors, we propose a CTR model that enables Dynamic Embedding Learning with Truncated Conscious Attention for CTR prediction, termed DELTA.
