Adaptive Sensitivity Analysis for Robust Augmentation against Natural Corruptions in Image Segmentation

ICML 2025poster

Achieving robustness in image segmentation models is challenging due to the fine-grained nature of pixel-level classification. These models, which are crucial for many real-time perception applications, particularly struggle when faced with natural corruptions in the wild for autonomous systems. Whi…

Gradient Informed Proximal Policy Optimization

NeurIPS 2023poster

We introduce a novel policy learning method that integrates analytical gradients from differentiable environments with the Proximal Policy Optimization (PPO) algorithm. To incorporate analytical gradients into the PPO framework, we introduce the concept of an α-policy that stands as a locally superi…

Gradient-Free Adversarial Training Against Image Corruption for Learning-based Steering

NeurIPS 2021poster

We introduce a simple yet effective framework for improving the robustness of learning algorithms against image corruptions for autonomous driving. These corruptions can occur due to both internal (e.g., sensor noises and hardware abnormalities) and external factors (e.g., lighting, weather, visibil…
