I'm trying to classify images using NN classifier available in Matlab R2019a.
I have 1800 images into 3 classes (Hard, Semi, Soft).
I have 68 features (descriptors).
When I classify into 2 classes (hard or soft): I get 93% accuracy
When I classify into 3 classes (hard -- semi -- soft): I get 75% accuracy
Question is: how to improve the accuracy for the 3 classes model?
Any ideas?
P.S. I can always send a sample data file if needed.

You will need to try various NN models, to try and improve your accuracy.
Also try all the models in the classification learner app.
