  6. Pipeline for r esti timati ting th the Recepti tive Fields: Goal is to identify which regions of the image lead to the high unit activations. Di Discr crepancy cy map per unit 5000 occluded versions Zhou, Khosla, at al (2015). ICLR

  7. Pipeline for r esti timati ting th the Recepti tive Fields To To consolidate the information from several images, we ce center the discr crepancy cy map arou ound the spatial loca ocation on of of the uni unit t tha hat c caus used ed t the m he maximum um a activation f n for t the g he given i en image. e. Th Then we average the re-ce centered discr crepancy cy maps to o ge generate t the f final r recept ptive f field o d of e each gi given u unit. . Zhou, Khosla, at al (2015). ICLR
