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.
This document summarizes a presentation about variational autoencoders (VAEs) presented at the ICLR 2016 conference. The document discusses 5 VAE-related papers presented at ICLR 2016, including Importance Weighted Autoencoders, The Variational Fair Autoencoder, Generating Images from Captions with Attention, Variational Gaussian Process, and Variationally Auto-Encoded Deep Gaussian Processes. It also provides background on variational inference and VAEs, explaining how VAEs use neural networks to model probability distributions and maximize a lower bound on the log likelihood.

Deep reinforcement learning algorithms often fail to learn complex tasks. Recent works have identified three issues that form a "deadly triad" contributing to this problem: non-stationary targets, high variance, and positive correlation. New algorithms aim to address these issues by improving exploration, stabilizing learning, and decorrelating updates. Overall, deep reinforcement learning remains a challenging area with opportunities to develop more data-efficient and generally applicable algorithms.
