Caffe | Softmax with Loss Layer - Berkeley Vision

http://caffe.berkeleyvision.org/tutorial/layers/softmaxwithloss.html

The softmax loss layer computes the multinomial logistic loss of the softmax of its inputs. It’s conceptually identical to a softmax layer followed by a multinomial logistic loss layer, but provides a more numerically stable gradient. Parameters Parameters ( SoftmaxParameter softmax_param) From ./src/caffe/proto/caffe.proto:
