Today we’re joined by Christy Dennison, Machine Learning Engineer at OpenAI.

Since joining OpenAI earlier this year, Christy has been working on OpenAI’s efforts to build an AI-powered agent to play the DOTA 2 video game. Our conversation begins with an overview of DOTA 2 gameplay and the recent OpenAI Five benchmark which put the OpenAI agent up against a team of professional human players. We then dig into the underlying technology used to create OpenAI Five, including their use of deep reinforcement learning and LSTM recurrent neural networks, and their liberal use of entity embeddings, plus some of the tricks and techniques they use to train the model on 256 GPUs and 128,000 CPU cores.
