Challenge Problems
Push your limits with advanced challenges
Consider an MRF that consists of four variables X1, X2, X3, and X4. If the potential functions are φ(X1, X2), φ(X2, X3), and φ(X3, X4), derive the joint probability expression.
💡 Hint: Think of how each potential function contributes to the overall structure.
Discuss why MRFs could be inappropriate for certain types of problems that require unidirectional dependencies. Provide an example.
💡 Hint: Consider how temporal sequences impact relationships and if direction is vital.
