A Dual Stealthy Backdoor: From Both Spatial and Frequency Perspectives

2023 · arXiv (Cornell University)

Backdoor attacks pose serious security threats to deep neural networks (DNNs). Backdoored models make arbitrarily (targeted) incorrect predictions on inputs embedded with well-designed triggers while behaving normally on clean inputs. Many works have explored the …

Domain-specific Knowledge Guided Self-supervised Learning for Pathological Image Segmentation

2023

Self-supervised learning provides a possible solution to extract effective visual representations from unlabeled pathological images. However, most of the existing methods either do not effectively utilize domain-specific information or are designed and optimized for image …
