HNC loss

To use our loss, please first generate CAMs following this line.

Our loss can be found in HNC_mse and HNC_kd. The usage of loss can be found in this line, where our loss takes two arguments: CAMs and ground-truth label.

Note: 1. you may need to tune lambda, which is the weight balancing both HNC loss and cross entropy loss. Higher weight means higher influence of HNC loss; 2. you may need to tune k, which is the number of negative CAMs to suppress. Smaller k means focusing on more confusing classes.

ImageNet classification

1). prepare ImageNet dataset

2). for running commands, please refer to './imagenet/running-script.sh'
