%description
Interpretation methods for analyzing the behavior and individual
predictions of modern neural networks in a three-step procedure:
Converting the model, running the interpretation method, and visualizing
the results. Implemented methods are, e.g., 'Connection Weights' described
by Olden et al. (2004) <doi:10.1016/j.ecolmodel.2004.03.013>, layer-wise
relevance propagation ('LRP') described by Bach et al. (2015)
<doi:10.1371/journal.pone.0130140>, deep learning important features
('DeepLIFT') described by Shrikumar et al.  (2017) <arXiv:1704.02685> and
gradient-based methods like 'SmoothGrad' described by Smilkov et al.
(2017) <arXiv:1706.03825>, 'Gradient x Input' described by Baehrens et al.
(2009) <arXiv:0912.1128> or 'Vanilla Gradient'.
