Pretraining Deep Actor-Critic Reinforcement Learning Algorithms With Expert Demonstrations

2018 · arXiv (Cornell University)

Pretraining with expert demonstrations have been found useful in speeding up the training process of deep reinforcement learning algorithms since less online simulation data is required. Some people use supervised learning to speed up the …

Defending Against Universal Patch Attacks by Restricting Token Attention in Vision Transformers

2023

Previous works reveal that similar to CNNs, vision transformers (ViT) are also vulnerable to universal adversarial patch attacks. In this paper, we empirically reveal and mathematically explain that the shallow tokens in the transformer and …
