Copycat CNN

Here you can find the models, the datasets information and the code used in our experiments (Copycat and Copycat Expansion). Feel free to contact me for any questions or suggestions (jacsonrcsilva at gmail).

Note that we used the Caffe Framework (1, 2). Therefore, you will find the "prototxt" files to replicate our experiments.

But if you don't want to use Caffe, it is not a problem. In order to make it easier for you, we are also providing the following codes implemented in PyTorch:

• Copycat Example; and
• Copycat Framework to you apply/test Copycat Method against your own data.

Also, if you want to see an interactive comparison between Oracle and Copycat models, visit: Copycat CNN Explainer
It is implemented in TensorflowJS, using the CNN Explainer system.
