How to increase class label accuracy

[sarwarmurshed]

Hello,

I am using mask_rcnn_R_50_FPN_3x.yaml model on my private slap fingerprint dataset to segment the fingerprints and label them. In my dataset, There are 118K images and 10 classes. Classes are: left_index, left_middle, left_ring, left_little, right_index, right_middle, right_ring, right_little, left_thumb, right_thumb.

I am satisfied with the bounding box accuracy. However, not happy with the class label accuracy. The class label accuracy is only 94%. I am expecting to achieve 98% accuracy. I tried to train the model with different learning rates but had no luck.

Is there any way to improve class label accuracy? Any suggestion would be greatly appreciated.
