Scenic4RL: Programmatic Modeling and Generation of Reinforcement Learning Environments

2021 · arXiv (Cornell University)

The capability of a reinforcement learning (RL) agent heavily depends on the diversity of the learning scenarios generated by the environment. Generation of diverse realistic scenarios is challenging for real-time strategy (RTS) environments. The RTS …

Semantic Adversarial Attacks via Diffusion Models

2023 · arXiv (Cornell University)

Traditional adversarial attacks concentrate on manipulating clean examples in the pixel space by adding adversarial perturbations. By contrast, semantic adversarial attacks focus on changing semantic attributes of clean examples, such as color, context, and features, …
