Label Scarcity Reveals Architecture-Dependent Robustness in CNN-Based Casting Defect Detection

Tengxiao Liu, Hongtao Sun

Deep learning for automated visual inspection in manufacturing is often limited by the cost of labeling large image datasets. Using 7,348 casting images, we evaluated how three CNN architectures, ResNet18, ResNet50, and MobileNetV3-Small, tolerate progressively reduced labeling b…Read more

Driving Decisions for Autonomous Vehicles in Intersection Environments: Deep Reinforcement Learning Approaches with Risk Assessment

Wangpengfei Yu, Yubin Qian, Jiejie Xu, Hongtao Sun, Junxiang Wang

Intersection scenarios are one of the most complex and high-risk traffic scenarios. Therefore, it is important to propose a vehicle driving decision algorithm for intersection scenarios. Most of the related studies have focused on considering explicit collision risks while lackin…Read more
