What are some examples of fitness functions in AI?

Fitness functions are used to evaluate how well a solution solves a problem. For example, in genetic algorithms, a fitness function might assess how close a solution is to the optimal result.

Can you give me a specific example of a fitness function?

Sure! In a traveling salesman problem, a fitness function could calculate the total distance of a proposed route, aiming to minimize that distance.

How do fitness functions impact machine learning models?

Fitness functions guide the optimization process in machine learning, helping to select the best model parameters by evaluating their performance.

Are there any common pitfalls when designing fitness functions?

Yes, common pitfalls include overfitting to the fitness function, ignoring important constraints, and making the function too complex.
