💥 What’s New in AI: DeepMind’s New Method for Discovering when an Agent is Present in a System

So very often, the terms “agents” and “models” are used interchangeably in machine learning. Conceptually, a model is the mathematical and architecture representation of a knowledge task. A model receives some inputs and produces some outputs based on its knowledge acquired via the exploration of some datasets. An agent is composed of one or more models but has the distinct characteristic that they interact with an environment in order to refine their knowledge or policy. From that perspective, an agent is not necessarily a model (although that point is debatable) but is rather composed of one or more models.

So, in short, agents are groups of models that actively interact with an environment and modify their policy accordingly. Following that definition, one of the most important challenges in agent modeling is to understand their behavior sensitivity to ecological interactions. Recently, ...
