I am trying to develop a neural network that can estimate the stress concentration factor Kt of V-notched specimens based on scans from the notch profile. The scans have been interpolated to create regions of equidistant points, as I want to use a 1D CNN that can interpret the height values of the profile. I have approximately 150 samples. The mean Kt value of the samples is 2.27 with a std of 0.17.
