Hi,

I am getting to know MATLAB's capability with deep learning (I am fluent in TensorFlow).

I built a very big computation graph.

My question is :

How can I get a specific layer's output sizes without training the network? (for dubugging purposes)

I know that I can do:

features = activations(net,X,layer)

but this requires me to train the network (I want to avoid it since it will take a while).

Thanks

Hi Itzik,

Have you tried analyzeNetwork?

net.Layers().Weights give you the learned parameters. Specify the layer number in bracket.

@Mirko Prezioso: A new class NetworkAnalysis will be added from R2024a. This class can be retrieved as an output of analyzeNetwork function, and will capture the output of analyzeNetwork. This will include a property called "LayerInfo" as a table.
