Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a small Bayesian network for a weather prediction system. Demonstrate how you would apply variable elimination to determine the probability of rain given humidity and pressure.

💡 Hint: Consider how different weather conditions might relate to each other.

Challenge 2 Hard

Analyze a situation where variable elimination would yield inefficient results due to cyclical dependencies in a Bayesian network. Propose an alternative method for inference.

💡 Hint: Think about the graph structures involved.
