Hi,
I need some help with the problem I mentioned in the summarized question. I have images about engraved surfaces, I would like to train the network to segment the engraved and the not engraved areas on them. The learning process goes well until the 11th iteration, where it starts fluctuating. I have 65 [200x200] training images (not too much, but should be enough to get a partly "smart" network at the end). After the 100 epochs I open 2 figures (1 picture from the training images and 1 completely new picture).
Most of the time as a result I get every pixels classified as "non_engraved". These times the mini-batch accuracy remains constant after earned the 72%.
This time (randomly) the mini-batch accuracy went up to 86% (but still with fluctuating), and got a better result, but it is still disappointment:

If you would like to check my code, I attached "Sajat.m"
I'm a completely beginner MATLAB user. Could someone help me?
Huge thanks in advance!

Hi Peter,
In order to prevent the fluctuation in the results, you can try updating the learning rate adaptively while training the network. For achieving that you can refer to the "LearnRateSchedule", "LearnRateDropFactor" and "LearnRateDropPeriod" options of the "trainingOptions" that MATLAB provides.
https://www.mathworks.com/help/deeplearning/ref/trainingoptions.html
Other than that you can also use "imageDataAugmenter" to augment your dataset. This would be helpful since you only have 65 training images right now. Data augmentation can artificially expand the size of your training set by applying various transformations like rotation, scaling, flipping, and cropping, or even adding noise. This can help the network learn more robust features and improve its generalization capability. You can refer to the following MathWorks documentation to understand more about "imageDataAugmenter".
https://www.mathworks.com/help/deeplearning/ref/imagedataaugmenter.html
I hope this helps.
