LossKLD 
Kullback Leibler Divergence loss function

LossL1 
L1 loss function: i.e., sum of absolute errors, L = sum_i abs(predicted_i  actual_i)
See also
LossMAE for a mathematically similar loss function (MAE has division by N, where N is output size) 
LossL2 
L2 loss function: i.e., sum of squared errors, L = sum_i (actual_i  predicted)^2
The L2 loss function is the square of the L2 norm of the difference between actual and predicted.

LossMAE 
Mean absolute error loss function: L = 1/N sum_i abs(predicted_i  actual_i)

LossL1 for a mathematically similar loss function (LossL1 does not have division by N, where N is output size)

LossMCXENT 
MultiClass Cross Entropy loss function:
L = sum_i actual_i * log( predicted_i ) 
LossMSE 
Mean Squared Error loss function: L = 1/N sum_i (actual_i  predicted)^2
See also
LossL2 for a mathematically similar loss function (LossL2 does not have division by N, where N is output size) 
LossMSLE 
Mean Squared Logarithmic Error loss function: L = 1/N sum_i (log(1+predicted_i)  log(1+actual_i))^2

LossNegativeLogLikelihood 
Negative log likelihood loss function
