Diagnosing Ensemble Few-Shot Classifiers

no code implementations9 Jun 2022 Weikai Yang, Xi Ye, Xingxing Zhang, Lanxi Xiao, Jiazhi Xia, Zhongyuan Wang, Jun Zhu, Hanspeter Pfister, Shixia Liu

The base learners and labeled samples (shots) in an ensemble few-shot classifier greatly affect the model performance.

SMAP: A Joint Dimensionality Reduction Scheme for Secure Multi-Party Visualization

no code implementations30 Jul 2020 Jiazhi Xia, Tianxiang Chen, Lei Zhang, Wei Chen, Yang Chen, Xiaolong Zhang, Cong Xie, Tobias Schreck

We build a prototype system based on our method, SMAP, to support the organization, computation, and exploration of secure joint embedding.

Scale-Invariant Structure Saliency Selection for Fast Image Fusion

1 code implementation30 Oct 2018 Yixiong Liang, Yuan Mao, Jiazhi Xia, Yao Xiang, Jianfeng Liu

Specifically, we propose a scale-invariant structure saliency selection scheme based on the difference-of-Gaussian (DoG) pyramid of images to build the weights or activity map.
