Add a dropout layer to a narxnet

Hello everyone

Once I create a narxnet (for example thisone with three layers and 10 neurons eachone: net = narxnet(1:2,1:2, [10 10 10],'open', 'trainlm'))

How can I add a dropout layer to it?

Thanks in advance.

Hi Elieser,

I understand from your query that you want to know how to add a dropout layer to 'narnet' neural network.

The 'narxnet' function does not provide an option to add dropout layer directly. However, you can add the dropout by defining a custom transfer function to one of the layers. Details on how to create a custom transfer function is addressed in the following MATLAB Answer:

Hope this helps!

Thank you for your answer Rishi

Could you explain a little bit how the transfer function works?

On one hand I have the narxnet, on the other the new layer: What does the function transfer? Is it the new layer the variable 'mytf'? How does it knows what network am I refering to?

function add_trfcn(fname)

open_system('neural');

open_system('neural/Transfer Functions');

set_param('neural','Lock','off')

add_block('simulink/User-Defined Functions/Interpreted MATLAB Function',['neural/Transfer' char(13) 'Functions/',fname], 'matlabfcn',fname,'name',fname)

Thanks in advance
