Prototype for a Reinforcement Learning-based Controller for a Fortune 500 Chemical Company

Prototyped a reinforcement learning-based controller for a Fortune 500 company in the chemical goods industry. The controller was utilized for predictive maintenance tasks. We went from advising, data collection, data understanding, model development, and iterations over clients all the way to deploying the dockerized models in a LAN of the factory on-site. The model was tested during COVID-19. Due to the limited robustness of RL-based models, the model was used as a predictive maintenance use case.
