This Looks Like That... Does it? Shortcomings of Latent Space Prototype Interpretability in Deep Networks

This repository contains code for reproducing experiments and models from the paper "This Looks Like That... Does it? Shortcomings of Latent Space Prototype Interpretability in Deep Networks" by Adrian Hoffmann*, Claudio Fanconi*, Rahul Rade* and Jonas Kohler.

A short version of the paper has been accepted at the ICML 2021 Workshop on Theoretic Foundation, Criticism, and Application Trend of Explainable AI.

Head-On-Stomach Experiment	JPEG Experiment

Setup

Installation

Clone this repository.

$ git clone https://gitlab.ethz.ch/fanconic/this-does-not-look-like-that
$ cd this-does-not-look-like-that

We suggest to create a virtual environment and install the required packages.

$ conda create --name experiment_env
$ conda activate experiment_env
$ conda install --file requirements.txt

Dataset

Download the CUB-200-2011 dataset from http://www.vision.caltech.edu/datasets/cub_200_2011/ and extract the files in a suitable folder.

Training ProtoPNets

Please set the variable base_architecture in settings.py to the backbone which you want to use for the ProtoPNet. Also, set the path to the downloaded dataset in src/data/setup.py.

Training ProtoPNets used in the Head-On-Stomach experiment.

$ ./run_training.sh

Training ProtoPNets used in the JPEG experiment.

$ ./run_jpeg_training.sh
