Semi supervised, weakly-supervised, unsupervised, and active learningYusuke Uchida
An overview of semi supervised learning, weakly-supervised learning, unsupervised learning, and active learning.
Focused on recent deep learning-based image recognition approaches.
This document summarizes recent developments in action recognition using deep learning techniques. It discusses early approaches using improved dense trajectories and two-stream convolutional neural networks. It then focuses on advances using 3D convolutional networks, enabled by large video datasets like Kinetics. State-of-the-art results are achieved using inflated 3D convolutional networks and temporal aggregation methods like temporal linear encoding. The document provides an overview of popular datasets and challenges and concludes with tips on training models at scale.
【DL輪読会】Diffusion Policy: Visuomotor Policy Learning via Action DiffusionDeep Learning JP
This document discusses a paper on visuomotor policy learning via action diffusion. The paper presents a method for training policies that map camera images directly to actions by incorporating action diffusion, which adds noise to actions during training. This helps explore the action space and avoid getting stuck in local optima during policy learning. The method can learn policies for complex manipulation tasks entirely from pixels using self-supervised reinforcement learning with image rewards.
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.
