Name

create_dl_layer_lrnT_create_dl_layer_lrnCreateDlLayerLrnCreateDlLayerLrncreate_dl_layer_lrn — Create a LRN layer.

Signature

Description

The operator create_dl_layer_lrncreate_dl_layer_lrnCreateDlLayerLrnCreateDlLayerLrncreate_dl_layer_lrn creates a local response normalization layer which performs normalization over a local window and whose handle is returned in DLLayerLRNDLLayerLRNDLLayerLRNDLLayerLRNdllayer_lrn. Currently, for NormRegionNormRegionNormRegionnormRegionnorm_region only 'across_channels'"across_channels""across_channels""across_channels""across_channels" can be set, which results in a normalization across the channel dimension. More detailed, a value located in a channel with index is normalized with a scale factor depending on a local window,

where is the size of the local window given by LocalSizeLocalSizeLocalSizelocalSizelocal_size, is the total number of channels, AlphaAlphaAlphaalphaalpha is the scaling parameter (used as a normalization constant), BetaBetaBetabetabeta is the exponent used as a contrast constant, and KKKkk is a constant summand, which is used to avoid any singularities.

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 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"

Certain parameters of layers created using this operator create_dl_layer_lrncreate_dl_layer_lrnCreateDlLayerLrnCreateDlLayerLrncreate_dl_layer_lrn can be set and retrieved using further operators.
