1 Abdallah Kassir 1

2 Information Theory Entropy: Conditional Entropy: Mutual Information: 2

3 Abdallah Kassir Optimal Sensor Parameter Selection MMI: Maximum Mutual Information 3

4 Abdallah Kassir Example: 12 Coin Problem 4

5 Abdallah Kassir Problem Need to learn: Need to solve: 5

6 Abdallah Kassir Observation Model Can be learnt over many experiments Or, modelled by recognition system 6

7 Abdallah Kassir Solve argmax problem Integral difficult to compute: Discretise Or, use Monte Carlo methods to estimate Even if we can compute the MI, we also need to maximise. Local maxima possible 7

8 Abdallah Kassir Experimental Results 8 MI Max MI

9 Abdallah Kassir Experimental Results 9

10 Abdallah Kassir Experimental Results 10
