Loss Function for task

손실 함수는 수행하고자 하는 작업 종류에 따라 변합니다.

• Regression Task

  $MSE=\frac{1}{N}{\sum }_{i=1}^N{\sum }_{d=1}^D{(y_i^d-{\hat{y}}_i^d)}^2$

• Classification Task

$CE=-\frac{1}{N}{\sum }_{i=1}^N{\sum }_{d=1}^D(y_i^d\log {\hat{y}}_i^d)$

• Probabilistic Task

$MLE=\frac{1}{N}{\sum }_{i=1}^N{\sum }_{d=1}^D\log N(y_i^d;{\hat{y}}_i^d,1)=MSE$
