Hi,

You set the value min(c)=20 for ImageNet in '.ipynb' file. How to set the value of min(c) for other datasets, such as COCO or NUS_WIDE?

The min(c) is an empirical value. In our experiments, we choose min(c) in the range of K/4 to K/3. Actually, we found that our method is robust with this value.
