Better Trigger Inversion Optimization in Backdoor Scanning
TL;DR: A new optimization method is developed that directly minimizes individual pixel changes, without using a mask, that can generate triggers that require a smaller number of input pixels to be perturbed, have a higher attack success rate, and are more robust.
Journal ArticleDOI
Multi-modal brain tumor image segmentation based on SDAE
TL;DR: It can be proven that the proposed method for segmenting brain tumor images from multi‐modal magnetic resonance imaging volumes based on stacked de‐noising auto‐encoders (SDAEs) obtains the better performance than other state‐of‐the‐art counterpart methods.
Proceedings ArticleDOI
Complex Backdoor Detection by Symmetric Feature Differencing
TL;DR: Wang et al. as discussed by the authors used a trigger inversion technique to generate triggers, namely, universal input patterns flipping victim class samples to a target class, and then checked if any such trigger is composed of features that are not natural distinctive features between the victim and target classes.

PENet: Object Detection using Points Estimation in Aerial Images.
TL;DR: A novel network structure, Points Estimated Network (PENet), is proposed in this work to answer the challenges of identifying objects from aerial images, and showed that PENet achieved higher precision results than existing state-of-the-art approaches.
