  log_epsilon = 1e-10)

Arguments

predictions	one-hot encoded proba matrix (with (n,k)).
targets	one-hot encoded matrix (with (n,k)).
epsilon	clipping offset.
log_epsilon	log offset.

Value

numeric loss.

Examples

## Not run: 
cross_entropy_loss(matrix(c(0.25,0.01,0.25,0.01,0.25,0.01,0.25,0.96), nrow = 2),
                   matrix(c(0,0,0,0,0,0,1,1), nrow=2))
