This document discusses the connections between generative adversarial networks (GANs) and energy-based models (EBMs). It shows that GAN training can be interpreted as approximating maximum likelihood training of an EBM by replacing the intractable data distribution with a generator distribution. Specifically:
1. GANs train a discriminator to estimate the energy function of an EBM, with the generator minimizing that energy of its samples.
2. EBM training can be seen as alternatively updating the generator and sampling from it, in a manner similar to contrastive divergence for EBMs.
3. This perspective unifies GANs and EBMs, and suggests ways to combine their training procedures to leverage their respective advantages
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.
The document summarizes recent research related to "theory of mind" in multi-agent reinforcement learning. It discusses three papers that propose methods for agents to infer the intentions of other agents by applying concepts from theory of mind:
1. The papers propose that in multi-agent reinforcement learning, being able to understand the intentions of other agents could help with cooperation and increase success rates.
2. The methods aim to estimate the intentions of other agents by modeling their beliefs and private information, using ideas from theory of mind in cognitive science. This involves inferring information about other agents that is not directly observable.
3. Bayesian inference is often used to reason about the beliefs, goals and private information of other agents based

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.
The document provides a self-introduction by Takigawa Ichigaku, who specializes in machine learning and data-driven natural science research, particularly those involving discrete structures. It outlines his work experience and current affiliations with RIKEN and Hokkaido University. It then previews the topics to be covered in the talk, including machine learning applications in molecular representation and chemical reaction design, as well as challenges in interpreting machine learning models.
