Hi everyone,
How is it possible to use a sequenceInputLayer with a regressionLayer (neural networks)? I have tried the following code:
layers = [...
sequenceInputLayer(inputSize)
fullyConnectedLayer(30)
fullyConnectedLayer(1)
regressionLayer]
which results with the following error message:
Error using trainNetwork (line 140)
The output of layer 3 is incompatible with the input expected by layer 4.
I searched through the manual and have yet to find something that pertains to the expected input of a regressionLayer.
If someone happens to be able to share the relevant documentation or a snippet of code, that would be really helpful.
Thank you very much!

The regression layer is the only one that has no explicit indication of size.
Hope this helps.

The answer is obvious:
help regressionlayer
doc regressionlayer
