plot

Plot neural network architecture

Syntax

plot(net)

Description

plot(net) plots the layers and connections of the neural network net.

Tip

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

Examples

Plot Neural Network

Create a simple neural network and display it in a plot.

net = dlnetwork;

layers = [
    imageInputLayer([32 32 3])
    convolution2dLayer(3,16,Padding="same")
    batchNormalizationLayer
    reluLayer(Name="relu1")
    
    convolution2dLayer(3,16,Padding="same",Stride=2)
    batchNormalizationLayer
    reluLayer
    additionLayer(2,Name="add")];

net = addLayers(net,layers);
net = connectLayers(net,"relu1","add/in2");

figure
plot(net)

Input Arguments

net — Neural network

dlnetwork object

Neural network, specified as a dlnetwork object.

Version History

Introduced in R2017b

R2024a: DAGNetwork, SeriesNetwork, and LayerGraph objects are not recommended

Starting in R2024a, DAGNetwork, SeriesNetwork, and LayerGraph objects are not recommended. Use dlnetwork objects instead. This recommendation means that the that plot function is not recommended with inputs of these objects.

To convert a trained DAGNetwork or SeriesNetwork object to a dlnetwork object, use the dag2dlnetwork function.

Most functions that support LayerGraph objects also support dlnetwork objects. This table shows some typical usages of LayerGraph objects and how to update your code to use dlnetwork object functions instead.

Not Recommended	Recommended
lgraph = layerGraph;	net = dlnetwork;
lgraph = layerGraph(layers);	net = dlnetwork(layers,Initialize=false);
lgraph = layerGraph(net);	net = dag2dlnetwork(net);
lgraph = addLayers(lgraph,layers);	net = addLayers(net,layers);
lgraph = removeLayers(lgraph,layerNames);	net = removeLayers(net,layerNames);
lgraph = replaceLayer(lgraph,layerName,layers);	net = replaceLayer(net,layerName,layers);
lgraph = connectLayers(lgraph,s,d);	net = connectLayers(net,s,d);
lgraph = disconnectLayers(lgraph,s,d);	net = disconnectLayers(net,s,d);
plot(lgraph);	plot(net);

To train a neural network specified as a dlnetwork object, use the trainnet function.
