I can't understand the plotregression output from my neural network.

Hello community,

I trained a neural network and I looked at the output plotregression, see below.

Does that mean that my neural network has a bias at the output ?

Do I have to use linear fit on my nn output to get more accurate result ?

best regards

M.A.

Hi,

I understand that you want to know more details about the output of ‘plotregression()’ function.

The regression plot shows the actual network outputs plotted in terms of the associated target values. If the network has learned to fit the data well, the linear fit to this output-target relationship should closely intersect the bottom-left and top-right corners of the plot.

In your case it is not the case so further training, or training a network with more hidden neurons, is advisable.

For more details on ‘plotregression()’ function, you can go through the below documentation link-

Hope it helps!
