Signature

Description

The operator create_dl_layer_softmaxcreate_dl_layer_softmaxCreateDlLayerSoftmaxCreateDlLayerSoftmaxcreate_dl_layer_softmax creates a softmax layer whose handle is returned in DLLayerSoftMaxDLLayerSoftMaxDLLayerSoftMaxDLLayerSoftMaxdllayer_soft_max.

The parameter DLLayerInputDLLayerInputDLLayerInputDLLayerInputdllayer_input determines the feeding input layer and expects the layer handle as value.

The parameter LayerNameLayerNameLayerNamelayerNamelayer_name sets an individual layer name. Note that if creating a model using create_dl_modelcreate_dl_modelCreateDlModelCreateDlModelcreate_dl_model each layer of the created network must have a unique name.

The softmax layer applies the softmax function which is defined for each input as follows: where is the number of inputs. During training, the result of the softmax function is transformed by a logarithm function, such that the values are suitable as input to e.g., a cross entropy loss layer. This behavior can be changed by setting the generic parameter 'output_mode'"output_mode""output_mode""output_mode""output_mode", see below.

The following generic parameters GenParamNameGenParamNameGenParamNamegenParamNamegen_param_name and the corresponding values GenParamValueGenParamValueGenParamValuegenParamValuegen_param_value are supported:

'output_mode'"output_mode""output_mode""output_mode""output_mode":

This parameter determines if and in which case the output is transformed by a logarithm function:

• 'default'"default""default""default""default": During inference, the result of the softmax function is returned as output while during training, the softmax is further transformed by a logarithm function.

• 'no_log_training'"no_log_training""no_log_training""no_log_training""no_log_training": During training the result of the softmax function is not transformed by a logarithm function.

• 'log_inference'"log_inference""log_inference""log_inference""log_inference": The logarithm of the softmax is calculated during inference in the same way as during training.

Default: 'default'"default""default""default""default".

'is_inference_output'"is_inference_output""is_inference_output""is_inference_output""is_inference_output":

Determines whether apply_dl_modelapply_dl_modelApplyDlModelApplyDlModelapply_dl_model will include the output of this layer in the dictionary DLResultBatchDLResultBatchDLResultBatchDLResultBatchdlresult_batch even without specifying this layer in OutputsOutputsOutputsoutputsoutputs ('true'"true""true""true""true") or not ('false'"false""false""false""false").

Default: 'false'"false""false""false""false"
