text: Title: Identify Images in src and dst with has bad training
  Body: Hi there
  
  Is there an option how to seperate some images in src and dst which has bad values in training?
  i mean, if 90% is by 0.4 and the rest has spikes up to 1.0 it would be nice to sort them out and train them till de value drops down to the level of the other.
  
  [12:04:25][#137240][2662ms]**[1.3264]**[0.5461]
  [12:04:48][#137248][1400ms]**[0.6550]**[0.3033]
  
  It would be nice if i can sort out this images and train seperate. Is that possible? like a sort by loss value?
