Its functional version is … Web17 de fev. de 2024 · The negative normalized entropy is defined as. h: R > 0 n → R , h ( x) = ∑ i = 1 n x i log x i ∑ j = 1 n x j . Is this function convex? Its Hessian is given by. H i j = ∂ 2 h ∂ x i ∂ x j ( x) = δ i j x j − 1 ∑ j = 1 n x j , so the question is equivalent to asking if this matrix is positive semi-definite for all x ≻ 0.

WebThe normalized entropy is a measure of relative uncertainty . The value of normalized entropy lies between 0 and 1, so NH a (θ) ∈ [0, 1]. This leads to standardized measures which can be compared with one another . An analog measure 1− NH a (θ), called the information index, serves to measure the reduction in uncertainty .
