Convolutional Neural Net visualization

This is our implementation (plus a demo) of CNN feature visualization (Zeiler & Fergus, 2013).

The way to just look at the ipython notebook. Use link: http://nbviewer.ipython.org/github/guruucsd/CNN_visualization/blob/master/urban_tribe/caffe/deconv_demo.ipynb

The visualization result is not as clear as the paper shows. We assume it's because they use different architecture and we have a small dataset for visualization. However, it may due to undetected bugs (but we hope not..) If you find any mistakes in this code, please tell us!

To run

This notebook should be run from the guru2.ucsd.edu server. Installation of caffe can be quite challenging, and this notebook depends on a particular urban_tribes model that only exists on that server.

To run,

  • ssh -X [username@]guru2.ucsd.edu
  • Clone this repository
  • Run ipython notebook and open the CNN_visualization/urban_tribe/caffe/deconv_demo.ipynb file from the browser.
