#include <IMP/core/WeightedSumOfExponential.h>
Inheritance diagram for IMP::core::WeightedSumOfExponential:Negative logarithm of weighted sum of negative exponential of unary functions.
Given unary functions \( f_i(x) \) and weights \( w_i \), compute the function
\[ F(x) = -d \log\left[ \sum_i{ \left( w_i e^{-f_i(x) / d} \right) } \right] ,\]
where \( d \) is the denominator of the exponential. This is used when the functions \( f_i(x) \) are scores ( \( -\log(p) \)), and the desired score \( F(x) \) is the score resulting from the weighted convolution of their probability distributions.
