I added a very descriptive title to this issue. First return, then explore Published in Nature, 2021 Reinforcement learning promises to solve complex sequential-decision problems autonomously by specifying a high-level reward function only. The striking contrast between the substantial performance gains from Go-Explore and the simplicity of its mechanisms suggests that remembering promising states, returning to them, and exploring. Camera ready version of Go-Explore published in Abstract Reinforcement learning promises to solve complex sequential-decision problems autonomously Explorer. Explorer. We introduce Go-Explore, a family of algorithms that addresses these two challenges directly through the simple principles of explicitly 'remembering' promising states . . Code. The code for Go-Explore with a deterministic exploration phase followed by a robustification phase is located in the robustified subdirectory. This paper introduces Policy-based Go-Explore where the agent is. xxxxxxxxxx. Step 1: Create a new local Git repository. By first returning before exploring, Go-Explore avoids derailment by minimizing exploration in the return policy (thus minimizing failure to return) after which it can switch to a purely exploratory policy. Your first GitHub repository is created. It is difficult because random exploration in such scenarios can rarely discover successful states or obtain meaningful feedback. (a) Probabilistically select a state from the archive, guided by heuristics that prefer states associated with promising cells. If you've been active on GitHub.com, you can find personalized recommendations for projects and good first issues based on your past contributions, stars, and other activities in Explore. 580 | Nature | Vol 590 | 25 February 2021 Article First return, then explore Adrien Eet 1,2,3 , Joost Huizinga 1,2,3 , Joel Lehman 1,2, Kenneth O.

It dives into the mathematical explanation of several feature selection and feature transformation techniques, while also providing the algorithmic representation and implementation of some other techniques. The result is a neural network policy that reaches a score of 2500 on the Atari environment MontezumaRevenge. first-return-FES-HTML.

The "hard-exploration" problem refers to exploration in an environment with very sparse or even deceptive reward. # live syntax, and validation errors highlighted within the text. 2. xxxxxxxxxx. However, RL algorithms struggle when, as is often the case, simple and intuitive rewards provide sparse . This article explains and provides a comparative study of a few techniques for dimensionality reduction. I used the GitHub search to find a similar issue and didn't find it. It exploits the following principles: (1) remember previously visited states, (2) first return to a promising state (without exploration), then explore from it, and (3) solve simulated environments through any available means (including by introducing determinism), then .

To address this shortfall, we introduce a new algorithm called Go-Explore. In this experiment, the 'explore' step happens through random actions, meaning that the exploration phase operates entirely without a trained policy, which assumes that random actions have a.
