Pie & AI is a series of DeepLearning.AI meetups independently hosted by community groups. This event is hosted by Reinforcement Learning Zurich.

How to train RL Agents for Video Games:

Video games are the perfect setting for Reinforcement Learning application and research: they are virtual environments by definition and, as such, they allow for optimizations like parallel training and a 100% match between training environment and real world. They also have an additional bonus: they are super fun! As usual the key starting point is to formalize them as Markov-Decision-Processes, clearly identifying observation and action spaces. Having done that, most advanced techniques can be applied. Especially on most recent games, it is needed to leverage deep reinforcement learning, given the high dimensionality of the input.

Depending on the specific nature of the observations and action spaces (e.g. pixels or numbers, discrete or continuous) different deep learning architectures may be needed, and additional advanced techniques, such as Imitation Learning or self play, can play an important role. It is this huge passion for reinforcement learning and video games that gave birth to DIAMBRA | Dueling AI Arena (diambra.artificialtwin.com).

The AI Tournament:

DIAMBRA and RLZ just launched the AI Tournament, where the challenge is to train a RL agent to effectively play Dead Or Alive++. Agents will be evaluated once a week during the two months competition period. The best five will qualify for the final event in which they will compete live for the final prize.

We will discuss all technical details: the observation space configuration and how to use it, the four possible action spaces available and the default reward function. We will take a look at the tournament repository, see how to interact with the environment and how to compose a valid submission.

Finally, we will compare a random agent with a trained Proximal Policy Optimization one, to demonstrate environment learnability.
