Question
3. Maximum Entropy Estimation:
Shannon's entropy is defined as:
where
H(p)=1 Pi ln pi
Possibility of each event: pi = p(xi) = [0, 1]
You are given a six-sided dice numbered from 1 to 6. You are given the information that
the average result from 10000 times of rolling dice is E[x]=3.5. What is your estimation
of the probabilities associated with different sides (what is the probabilities of having 1,
respectively)?
2,...,
The following nonlinear optimization problem
6
max H (p) subject to Σi±1 P₁ = 1, Σ²±1 xipi = = E[x]
i=1
gives the least-biased probability distribution
(a) Solve this problem by calling an optimization solver. Include your script and result
output. Plot how the probabilities change as E[x] varies between 1 and 6.
(b) Derive the optimality conditions using Lagrange Multiplier Method. Save this result,
as we will come back to it in the next homework assignment.
