addLayers

Add layers to layer graph or network

Syntax

lgraphUpdated = addLayers(lgraph,larray)

netUpdated = addLayers(net,larray)

Description

lgraphUpdated = addLayers(lgraph,larray) adds the network layers in larray to the layer graph lgraph. The updated layer graph lgraphUpdated contains the layers and connections of lgraph together with the layers in larray, connected sequentially. The layer names in larray must be unique, nonempty, and different from the names of the layers in lgraph.

netUpdated = addLayers(net,larray) adds the network layers in larray to the dlnetwork object net. The updated network netUpdated contains the layers and connections of net together with the layers in larray, connected sequentially. The layer names in larray must be unique, nonempty, and different from the names of the layers in net.

Examples

Add Layers to Layer Graph

Create an empty layer graph and an array of layers. Add the layers to the layer graph and plot the graph. addLayers connects the layers sequentially.

lgraph = layerGraph;

layers = [
    imageInputLayer([32 32 3],'Name','input')  
    convolution2dLayer(3,16,'Padding','same','Name','conv_1')
    batchNormalizationLayer('Name','BN_1')
    reluLayer('Name','relu_1')];

lgraph = addLayers(lgraph,layers);
figure
plot(lgraph)

Input Arguments

lgraph — Layer graph

LayerGraph object

Layer graph, specified as a LayerGraph object. To create a layer graph, use layerGraph.

net — Neural network

dlnetwork object

Neural network, specified as a dlnetwork object.

larray — Network layers

Layer array

Network layers, specified as a Layer array.

For a list of built-in layers, see List of Deep Learning Layers.

Output Arguments

lgraphUpdated — Updated layer graph

LayerGraph object

Updated layer graph, returned as a LayerGraph object.

netUpdated — Updated network

dlnetwork object

Updated network, returned as an uninitialized dlnetwork object.

To initialize the learnable parameters of a dlnetwork object, use the initialize function.

The addLayers function does not preserve quantization information. If the input network is a quantized network, then the output network does not contain quantization information.
