Non-Visible Light Data Synthesis and Application: A Case Study for Synthetic Aperture Radar Imagery

no code implementations29 Nov 2023 Zichen Tian, Zhaozheng Chen, Qianru Sun

If large-scale models pre-trained with regular images can be adapted to generating novel SAR images, the problem is solved.

Extracting Class Activation Maps from Non-Discriminative Features as well

1 code implementation CVPR 2023 Zhaozheng Chen, Qianru Sun

Extracting class activation maps (CAM) from a classification model often results in poor coverage on foreground objects, i. e., only the discriminative region (e. g., the "head" of "sheep") is recognized and the rest (e. g., the "leg" of "sheep") mistakenly as background.

Class Re-Activation Maps for Weakly-Supervised Semantic Segmentation

1 code implementation CVPR 2022 Zhaozheng Chen, Tan Wang, Xiongwei Wu, Xian-Sheng Hua, Hanwang Zhang, Qianru Sun

Specifically, due to the sum-over-class pooling nature of BCE, each pixel in CAM may be responsive to multiple classes co-occurring in the same receptive field.

Meta-Transfer Learning through Hard Tasks

1 code implementation7 Oct 2019 Qianru Sun, Yaoyao Liu, Zhaozheng Chen, Tat-Seng Chua, Bernt Schiele

In this paper, we propose a novel approach called meta-transfer learning (MTL) which learns to transfer the weights of a deep NN for few-shot learning tasks.
