plot

Plot neural network layer graph

Syntax

plot(lgraph)

plot(net)

Description

plot(lgraph) plots a diagram of the layer graph lgraph. The plot function labels each layer by its name and displays all layer connections.

Tip

To create an interactive network visualization and analyze the network architecture, use deepNetworkDesigner(lgraph). For more information, see Deep Network Designer.

plot(net) plots a diagram of the network net.

Examples

Plot Layer Graph

Create a layer graph from an array of layers. Connect the 'relu_1' layer to the 'add' layer.

layers = [
    imageInputLayer([32 32 3],'Name','input')   
    convolution2dLayer(3,16,'Padding','same','Name','conv_1')
    batchNormalizationLayer('Name','BN_1')
    reluLayer('Name','relu_1')
    
    convolution2dLayer(3,16,'Padding','same','Stride',2,'Name','conv_2')
    batchNormalizationLayer('Name','BN_2')
    reluLayer('Name','relu_2') 
    additionLayer(2,'Name','add')];

lgraph = layerGraph(layers);
lgraph = connectLayers(lgraph,'relu_1','add/in2');

Plot the layer graph.

figure
plot(lgraph);

Plot DAG Network

Load a pretrained GoogLeNet convolutional neural network as a DAGNetwork object. If the Deep Learning Toolbox™ Model for GoogLeNet Network support package is not installed, then the software provides a download link.

net = googlenet

net = 
  DAGNetwork with properties:

         Layers: [144×1 nnet.cnn.layer.Layer]
    Connections: [170×2 table]

Plot the network.

figure('Units','normalized','Position',[0.1 0.1 0.8 0.8]);
plot(net)

Plot Series Network

Load a pretrained AlexNet convolutional neural network as a SeriesNetwork object. If the Deep Learning Toolbox™ Model for AlexNet Network support package is not installed, then the software provides a download link.

net = alexnet

net = 
  SeriesNetwork with properties:

         Layers: [25x1 nnet.cnn.layer.Layer]
     InputNames: {'data'}
    OutputNames: {'output'}

Plot the network.

plot(net)
