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. 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. master.

The code for Go-Explore with a deterministic exploration phase followed by a robustification phase is located in the robustified subdirectory. I searched the SQLModel documentation, with the integrated search. and failing to first return to a state before exploring from it (derailment). Figure 1: Overview of Go-Explore. edited.

The "hard-exploration" problem refers to exploration in an environment with very sparse or even deceptive reward.

Click on the "+" button in the top-right corner, and then on "New project". We introduce Go-Explore, a family of algorithms that addresses these two challenges directly through the simple principles of explicitly 'remembering' promising states . For questions, bug reports, and discussions about GitHub Apps, OAuth Apps, and API development, explore the APIs and Integrations discussions on GitHub Community. However, reinforcement learning algorithms struggle when, as is often the case, simple and intuitive rewards provide sparse and deceptive feedback. It is difficult because random exploration in such scenarios can rarely discover successful states or obtain meaningful feedback. Code for the original paper can be found in this repository under the tag "v1.0" or the release "Go-Explore v1". Explorer. However, reinforcement learning algorithms struggle when, as is often the case, simple and intuitive rewards provide sparse 1 and deceptive 2 feedback. 2. I added a very descriptive title to this issue. The promise of reinforcement learning is to solve complex sequential decision problems autonomously by specifying a high-level reward function only. ()Go-Explore() . 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.
