Recently I have been experiencing a strange behavior in graph lab create. I have 121 Classes ( All scanned documents ). On the same data I was able to train a classifier on 128x128 image size which gave me good accuracy. Now I resized my data to 224x224 to see if it will perform better. The classifier training accuracy reaches some high point in the initial iterations and then drops to zero. I have run the experiment multiple times. It shows the same behavior when i increase the number of classes to 122 on 128x128 image size as well. I completely fail to grasp a reason for this. Please have a look at the following snippets.
This is the model that I am using
Please let me know if there is something wrong with my parameters or is it some bug in the library. Thanks
