This is the code base used to reproduce the "fooling" images in the paper:

This is an installation process that requires two main software packages (included in this package):

1. Caffe: https://caffe.berkeleyvision.org

• Our libraries installed to work with Caffe
  • Cuda 6.0
  • Boost 1.52
  • g++ 4.6

2. Sferes: https://github.com/jbmouret/sferes2

• Our libraries installed to work with Sferes
  • OpenCV 2.4.10
  • Boost 1.52
  • g++ 4.9 (a C++ compiler compatible with C++11 standard)

Note: These are specific versions of the two frameworks with our additional work necessary to produce the images as in the paper. They are not the same as their master branches.

Please see the Installation_Guide for more details.

• An MNIST experiment (Fig. 4, 5 in the paper) can be run directly on a local machine (4-core) within a reasonable amount of time (around ~5 minutes or less for 200 generations).
• An ImageNet experiment needs to be run on a cluster environment. It took us ~4 days x 128 cores to run 5000 generations and produce 1000 images (Fig. 8 in the paper).
• How to configure an experiment to test the evolutionary framework quickly
• To reproduce the gradient ascent fooling images (Figures 13, S3, S4, S5, S6, and S7 from the paper), see the documentation in the caffe/ascent directory. You'll need to use the ascent branch instead of master, because the two required versions of Caffe are different.

• Our fork project here has support for the latest Caffe and experiments to create recognizable images instead of unrecognizable.

Please refer to the licenses of Sferes and Caffe projects.
