Upside-Down RL

This project implements an Upside-Down Reinforcement Learning (UDRL) agent.

Installation

Make sure you have Python 3.10 installed. You can check your version with python --version. NOTE Use a virtual env to avoid dependency clash
Install the project dependencies using Poetry:
```
poetry install
```
If you do not have poetry use pip to install the requirements like so:
```
pip install -r requirements.txt
```

Running the Experiment

You can run the experiment with various configuration options using the command line:

poetry run python -m udrl [options]

Note If you are already inside a virtual env python -m udrl [options] is enough Note All defaults are for the CartPole-v0 Available options include:

--env_name: Name of the Gym environment (default: CartPole-v0)
--estimator_name: "neural" for NN or a fully qualified name of the scikit-learn estimator class (default: ensemble.RandomForestClassifier)
--seed: Random seed (default: 42)
--max_episode: Maximum training episodes (default: 500)
--collect_episode: Episodes to collect between training (default: 15)
--batch_size: Batch size for training (default: 0, uses entire replay buffer)
Other options related to warm-up, memory size, exploration, testing, saving, etc.

NOTE Cartpole, Acrobot, Mountain car and LunarLander envs were tested

Result Data

Experiment configuration and final test results are saved in a JSON file (conf.json) within a directory structure based on the environment, seed, and non-default configuration values (e.g., data/[env-name]/[experiment_name]/[seed]/conf.json).
If save_policy is True, the trained policy is saved in the same directory (policy).
If save_learning_infos is True, learning infos and rewards during training are saved as a NumPy file (e.g.test_rewards.npy) and a json file (e.h.learning_infos.json) in the same directory.

Process Data

A base post processing is available to convert the results data in csvs run it as python -m udrl.data_proc

Project Structure
