What is constraint propagation in machine learning?

Constraint propagation is a technique used to reduce the search space in machine learning by enforcing constraints on variables.

Can you give me an example of how it's used?

Sure! In a scheduling problem, constraint propagation can help eliminate impossible time slots for tasks based on their dependencies.

What are the benefits of using constraint propagation?

It helps improve efficiency by narrowing down possible solutions, leading to faster convergence in algorithms.

Are there any limitations to this approach?

Yes, it can be computationally expensive in complex problems and may not always lead to a solution.
