Study on Adversarial Robustness of Phishing Email Detection Models
Developing robust detection models against phishing emails has long been a main concerns of the cyber defense community. Currently public phishing/legitimate datasets are lack adversarial email examples which keeps the detection models vulnerable. To address this problem, we developed an augmented …

Towards Fully Automated Volumetric Analysis of Lung Nodules in Computed Tomography
Early detection of lung cancer significantly improves patient outcomes, and tracking the growth of lung nodules over time is key to understanding their progression and informing future treatment decisions. However, calculating nodule growth in computed tomography (CT) scans remains a highly manual …
