This document discusses self-supervised representation learning (SRL) for reinforcement learning tasks. SRL learns state representations by using prediction tasks as an auxiliary objective. The key ideas are: (1) SRL learns an encoder that maps observations to states using a prediction task like modeling future states or actions; (2) The learned state representations improve generalization and exploration in reinforcement learning algorithms; (3) Several SRL methods are discussed, including world models, inverse models, and causal infoGANs.
Several recent papers have explored self-supervised learning methods for vision transformers (ViT). Key approaches include:
1. Masked prediction tasks that predict masked patches of the input image.
2. Contrastive learning using techniques like MoCo to learn representations by contrasting augmented views of the same image.
3. Self-distillation methods like DINO that distill a teacher ViT into a student ViT using different views of the same image.
4. Hybrid approaches that combine masked prediction with self-distillation, such as iBOT.
This document summarizes a presentation on offline reinforcement learning. It discusses how offline RL can learn from fixed datasets without further interaction with the environment, which allows for fully off-policy learning. However, offline RL faces challenges from distribution shift between the behavior policy that generated the data and the learned target policy. The document reviews several offline policy evaluation, policy gradient, and deep deterministic policy gradient methods, and also discusses using uncertainty and constraints to address distribution shift in offline deep reinforcement learning.
[DL輪読会]Domain Adaptive Faster R-CNN for Object Detection in the WildDeep Learning JP
The document discusses domain adaptive faster R-CNN for object detection. It proposes a method to adapt a model trained on labeled data from a source domain to detect objects in an unlabeled target domain. The method uses an end-to-end deep learning model with two stages. First, it reduces differences in image distributions between the source and target domains. Then it performs object detection on the target domain images using the adapted model.
