WebApr 11, 2011 · 21. Hannah, you seem really confused about the "kroneker delta" thing. There are no delta functions involved here, the delta is being used as a partial derivative symbol. Back to the problem of differentiating and as to why the summation "disappears". Consider rewriting it slightly as I have below. WebNov 15, 2016 · See that sum() was removed from expression f, because the multiplying constant was moved into the sum() and the D(sum()) = sum(D()). Also the first constant was removed because the derivative is 0. Also the first …
WebJul 22, 2024 · Solution 1. Your derivation of p i log q i is fine. Based upon it we obtain for J: J = − ∑ j = 1 n p j z j + ∑ j = 1 n p j log ( ∑ k = 1 n e z k) (1) = − ∑ j = 1 n p j z j + log ( ∑ k = 1 n e z k) In the last line we use the sum of the probabilities p j, 1 ≤ j ≤ n is equal to 1.
