Roundup Here's your rapid-fire guide to what's been happening lately in the world of machine learning.

Multiagent madness: OpenAI has released materials to train a large number of neural-network-based software agents using reinforcement learning in multiplayer game environments.

Tech - Platform - Neural - MMO - Environments

The tech platform, dubbed Neural MMO, creates tile-based environments, in which bots move around trying to collect food and water to stay alive. There are a limited number of resources at any given time, and teams compete by attacking one another. Destroying opponents means there is less competition for food and water, so there's a higher chance of survival. The agents are rewarded for staying alive in the game for as long as possible.

Neural MMO supports up to 100 million lifetimes of 128 concurrent bots in 100 concurrent game servers. Developers can use it to craft their reinforcement learning algorithms for use in bots for massively multiplayer online (MMO) games.

Years - Multiagent - Settings - Platform - Reinforcement

"In recent years, multiagent settings have become an effective platform for deep reinforcement learning research," OpenAI explained this week. "Despite this progress, there are still two main challenges for multiagent reinforcement learning. We need to create open-ended tasks with a high complexity ceiling: current environments are either complex but too narrow or open-ended but too simple.

"Properties such as persistence and large population scale are key, but we also need more benchmark environments to quantify learning progress in the presence of large population scales and persistence. The game genre of Massively Multiplayer Online Games (MMOs) simulates a large ecosystem of a variable number of players competing in persistent and extensive environments."
