Challenge Problems

Push your limits with challenges.

Question 1

Design a belief propagation algorithm for a simplified network representing communicating sensors in an environment. What factors will you need to consider for the graph structure?

πŸ’‘ Hint: Think about how sensors are ideally arranged and their communication limitations.

Question 2

Given a cycle in a graphical model, argue why belief propagation may not yield accurate results. What modifications might improve its performance?

πŸ’‘ Hint: Consider the implications of cycles in information flow.
