Hi, Is it possible to train a Convolutional Neural Network for NxNxM inputs, where M is the size of the channel and is greater than 3?

The Image Input layer of a convolutional neural network only takes in NxNx1 (gray scale) or NxNx3 (RGB). However my data is NxNx25, is there a way to train this sort of data with Matlab?

Hi Vince,
As of now it is not possible to train a convolutional Neural Network to be able to work with more than 3 channels data.
This enhancement will be supported in one of the future releases of Neural Network Toolbox.

Can you please comfirm if multi channel is supported in latest matlab desktop version? (name the version)
I have observed that in matlab online, multichannel is acceptable for ImageInputLayer function.
inLayer=imageInputLayer([28 28 128])
inLayer =
ImageInputLayer with properties:
Name: ''
InputSize: [28 28 128]
DataAugmentation: 'none'
Normalization: 'zerocenter'
NormalizationDimension: 'auto'
Mean: []
