Loss function - AshokBhat/ml GitHub Wiki

Description

• Training performance metric
• Reflects quality of neural network
• Training goal is to minimize the loss function

Example loss functions

Function	Operation
MeanSquaredError	Mean of squares of errors between labels and predictions
MeanAbsoluteError	Mean of the absolute difference between labels and predictions
