What is Nash Equilibrium in Machine Learning?

Nash Equilibrium is a concept from game theory where no player can benefit by changing their strategy while others keep theirs unchanged. In machine learning, it can be applied to multi-agent systems where agents learn to optimize their strategies.

Can you give an example of how it works in a machine learning context?

Sure! Imagine two self-driving cars negotiating a route. If both cars choose their paths based on the other's decisions, they reach a Nash Equilibrium when neither car can improve its route without making the other worse off.

How does this concept help in training AI models?

It helps in designing algorithms that can predict and adapt to the strategies of other agents, leading to more robust and efficient learning in competitive environments.

Are there any limitations to using Nash Equilibrium in AI?

Yes, one limitation is that finding a Nash Equilibrium can be computationally intensive, and in some cases, multiple equilibria exist, making it challenging to determine the best strategy.
