The acrobot system includes two joints and two links, where the joint between the two links is actuated. This will perform the full training process on the model. The Acrobot in Python.

Initially, the links are hanging downwards, and the goal is to swing the end of the lower link The main reinformcent learning code is located in this file. To recap what we discussed in this article, Q-Learning is is estimating the aforementioned value of taking action a in state s under policy π – q. My Python journey began in 2007 and I have experience in Scientific Computing, Machine Learning, Web Development and DevOps. This model is saved as a TensorFlow model. Once you know your optimal parameters, enter them in 'full_training.py', and run 'python full_training.py'. To run the parameter search, run 'python search_params.py'. As you can see the policy still determines which state–action pairs are visited and updated, but nothing … Work fast with our official CLI. they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. Essentially it is described by the formula: A Q-Value for a particular state-action combination can be observed as the quality of an action taken from that state. TensorFlow A2C to solve Acrobot, with synchronized parallel environments. Initially, the links are hanging downwards, and the goal is to swing the end of the lower link up to a given height. This project is my capstone project for Udacity's Machine Learning Engineer Nanodegree. 为了做实验，发现有文章用OpenAI gym去做些小游戏的控制，主要是为了研究RL的算法，逐渐发现这个gym的例子成了standard test case.

As of September 20, 2016, the final learned model placed 3rd on the OpenAI Gym Acrobot-v1 leaderboard, with a score of -80.69 ± 1.06 (see "georgesung's algorithm"): https://gym.openai.com/envs/Acrobot-v1. To validate your model (make sure results are consistent), run 'python model_eval.py'. Work fast with our official CLI. You can experiment with the Acrobot dynamics in using, e.g. The acrobot system includes two joints and two links, where the joint between the two links is actuated. My final trained model is available at 'models/model.ckpt'. I'm not actually using the DDPG algorithm, and I'm not doing the "asynchronous" part of A3C :) Otherwise, I am using policy gradients with actor/critic networks, with advantage (A2C). However import config should work, since the ryan folder will be added to sys.path.
