Intuitive explanation of Adversarial machine learning

1

How would you explain Adversarial machine learning in simple layman terms for a non-STEM person? What are the main ideas behind Adversarial machine learning?

Consider a game being played between two people, for simplicity, we'll assume this game is distinguishing a true picture of a panda vs. a fake picture of a panda. The first player will take the painting and show it to the second player, if the second player guesses whether it is a fake correctly, they receive a reward, if not they do not. Both players are playing the game with the goal of maximizing their reward.

To go a little deeper but make it slightly more relevant to the context of Adversarial ML. We can further assume that both players start from 0 knowledge of pandas. You might imagine that player 1 just throws random colors at a canvas and tries to convince player 2, and player 2 just randomly guesses, slowly building their intuition for what a Panda is.

After several hours/days/years, we might find that both players are extremely skilled and drawing pandas and identifying fake pandas respectively.

This is really what adversarial ML is about in a nutshell. The goal is to have two agents with competing rewards, where their optimal solution is at some form of a mixed strategy Nash equilibrium.
