TeachMyAgent is a testbed platform for Automatic Curriculum Learning methods. We leverage Box2D procedurally generated environments to assess the performance of teacher algorithms in continuous task spaces.

This github repository provides implementations for the following teacher algorithms:
– Absolute Learning Progress-Gaussian Mixture Model (ALP-GMM), our proposed teacher algorithm
– Robust Intelligent Adaptive Curiosity (RIAC), from Baranes and Oudeyer, R-IAC: robust intrinsically motivated exploration and active learning.
– Covar-GMM, from Moulin-Frier et al., Self-organization of early vocal development in infants and machines: The role of intrinsic motivation.

This software implements the Imagine architecture, including a language-augmented goal-conditioned intrinsically motivated Deep RL agent. The agent freely explores its environment and turns natural language descriptions of interesting interactions from a social partner into potential goals. IMAGINE learns to represent goals by jointly learning a language model and a goal-conditioned reward function. Just like humans, our agent uses language compositionality to generate new goals by composing known ones. Leveraging modular model architectures based on Deep Sets and gated-attention mechanisms, IMAGINE autonomously builds a repertoire of behaviors and shows good zero-shot generalization properties for various types of generalization. When imagining its own goals, the agent leverages zero-shot generalization of the reward function to further train on imagined goals and refine its behavior. 

This software implements IMGEP-HOLMES, an algorithm that integrates a goal-based intrinsically-motivated exploration process (IMGEP) with the incremental learning of a hierarchy of behavioral characterization spaces (HOLMES). IMGEP-HOLMES is applied for the automated discovery of self-organized structures in Lenia, an artificial system (continuous cellular automaton).

The EpidemicOptimization suite is a library that allows to interface optimization algorithms with models of epidemic propagation. Epidemiological models are wrapped in OpenAI Gym interfaces, making them readily compatible with state-of-the-art optimization algorithms.

This folder hosts the code to reproduce the results presented in the paper Curiosity Driven Goal Exploration of Learned Disentangled Goal Spaces. In this paper, we study the impact of the structure of the representation when it is used as a goal space in Intrinsically Motivated Goal Exploration Processes. Experiments are performed on a simple task in which multi-joint arm must handle and gather an object in a 2D space in the presence of a distractor which cannot be handled and follows a random walk.

The Playground environment is designed to study systematic generalization in language-conditioned RL agents. The agent evolves in 2D scene with procedurally-generated objects that are characterized by their color (rgb), size, type and category. It is made easy to add more objects, categories, attributes, to add object- or category-specific interactions, goal descriptions, etc.
