Description

The operator create_dl_layer_activationcreate_dl_layer_activationCreateDlLayerActivationCreateDlLayerActivationcreate_dl_layer_activation creates an activation layer whose handle is returned in DLLayerActivationDLLayerActivationDLLayerActivationDLLayerActivationdllayer_activation.

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 parameter ActivationTypeActivationTypeActivationTypeactivationTypeactivation_type sets the type of the activation. Supported activation types are:

'relu'"relu""relu""relu""relu":

Rectified linear unit (ReLU) activation. By setting a specific ReLU parameter, another type can be specified instead of the standard ReLU:

• Standard ReLU, defined as follows:

• Bounded ReLU, defined as follows: Setting the generic parameter 'upper_bound'"upper_bound""upper_bound""upper_bound""upper_bound" will result in a bounded ReLU and determines the value of .

• Leaky ReLU:, defined as follows: Setting the generic parameter 'leaky_relu_alpha'"leaky_relu_alpha""leaky_relu_alpha""leaky_relu_alpha""leaky_relu_alpha" results in a leaky ReLU and determines the value .

'sigmoid'"sigmoid""sigmoid""sigmoid""sigmoid":

Sigmoid activation, which is defined as follows.

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

'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"

'upper_bound'"upper_bound""upper_bound""upper_bound""upper_bound":

Float value defining an upper bound for a rectified linear unit. If the activation layer is part of a model which has been created using create_dl_modelcreate_dl_modelCreateDlModelCreateDlModelcreate_dl_model, the upper bound can be unset. To do so, use set_dl_model_layer_paramset_dl_model_layer_paramSetDlModelLayerParamSetDlModelLayerParamset_dl_model_layer_param and set an empty tuple for 'upper_bound'"upper_bound""upper_bound""upper_bound""upper_bound".

Default: []

'leaky_relu_alpha'"leaky_relu_alpha""leaky_relu_alpha""leaky_relu_alpha""leaky_relu_alpha":

Float value defining the alpha parameter of a leaky ReLU.

Restriction: The value of 'leaky_relu_alpha'"leaky_relu_alpha""leaky_relu_alpha""leaky_relu_alpha""leaky_relu_alpha" must be positive or zero.

Default: 0.0
