Energy Loss Calculation (Extended Output)

Description

This function calculates the energy loss for given tensors, similar to energyloss(). The loss is calculated as the mean of the L2 norms between yt and mxt and between yt and mxpt, subtracted by half the mean of the L2 norm between mxt and mxpt. Unlike energyloss(), this function also returns the prediction loss s1 = E(|yt-mxt|) and variance loss s2 = E(|mxt-mxpt'|) as part of the output.

Usage

energylossall(yt, mxt, mxpt)

Arguments

yt	A tensor representing the target values.
mxt	A tensor representing the model's stochastic predictions.
mxpt	A tensor representing another draw of the model's stochastic predictions.

Value

A vector containing the calculated energy loss, s1, and s2.
