+  \item They argue that trust is crucial for effective human interaction with machine learning systems
+  \item Explaining individual predictions is important in assessing trust
+  \item They proposed LIME, a modular and extensible ap- proach to faithfully explain the predictions of any model in an interpretable manner
+  \item They introduced SP-LIME, a method to select representative and non-redundant predictions, providing a global view of the model to users.
+  \item Experiments demonstrated that explanations are useful for a variety of models in trust-related tasks in the text and image domains

+      \item This estimate of faithfulness can also be used for selecting an appropriate family of explanations from a set of multiple interpretable model classes, thus adapting to the given dataset and the classifier.

+    \item One issue that they do not mention in this work was how to perform the pick step for images.
