XWorld - A C++/Python simulator package for reinforcement learning

  •        2

This repository contains a collection of simulators for Reinforcement Learning research. XWorld features a teacher infrastructure implemented as a scheduler of multiple Finite State Machines (FSMs). The idea is that given the environment, the teacher can propose a task sampled (by some heuristics) from a task set. Each task - formulated as an FSM - has several stages, and the teacher does different things in different stages. The transition from one stage to another is determined by the envionment state, e.g., whehter the agent is idle or whether it has achieved the goal. Each stage returns several things including the next stage and the teacher's action. Currently, we define language (strings) as the teacher's sole action. However, the teacher is able to change the environment (e.g., adding/deleting objects, changing the map size, etc.) within each stage.

jetson-reinforcement - Deep reinforcement learning GPU libraries for NVIDIA Jetson with PyTorch, OpenAI Gym, and Gazebo robotics simulator

  •    C++

In this tutorial, we'll be creating artificially intelligent agents that learn from interacting with their environment, gathering experience, and a system of rewards with deep reinforcement learning (deep RL). Using end-to-end neural networks that translate raw pixels into actions, RL-trained agents are capable of exhibiting intuitive behaviors and performing complex tasks. Ultimately, our aim will be to train reinforcement learning agents from virtual robotic simulation in 3D and transfer the agent to a real-world robot. Reinforcement learners choose the best action for the agent to perform based on environmental state (like camera inputs) and rewards that provide feedback to the agent about it's performance. Reinforcement learning can learn to behave optimally in it's environment given a policy, or task - like obtaining the reward.

models - Model configurations

  •    Python

PaddlePaddle provides a rich set of computational units to enable users to adopt a modular approach to solving various learning problems. In this repo, we demonstrate how to use PaddlePaddle to solve common machine learning tasks, providing several different neural network model that anyone can easily learn and use. The word embedding expresses words with a real vector. Each dimension of the vector represents some of the latent grammatical or semantic features of the text and is one of the most successful concepts in the field of natural language processing. The generalized word vector can also be applied to discrete features. The study of word vector is usually an unsupervised learning. Therefore, it is possible to take full advantage of massive unmarked data to capture the relationship between features and to solve the problem of sparse features, missing tag data, and data noise. However, in the common word vector learning method, the last layer of the model often encounters a large-scale classification problem, which is the bottleneck of computing performance.
