This is done by weighting the perturbed images by their similarity to the instance we want to explain.9.2 Local Surrogate (LIME) | Interpretable Machine Learning,9.2 Local Surrogate (LIME). Local surrogate models are interpretable models that are used to explain individual predictions of black box machine learning models. Local interpretable model-agnostic explanations (LIME) 50 is a paper in which the authors propose a concrete implementation of local surrogate models. Surrogate models are trained to approximate the9 Local Interpretable Model-agnostic Explanations (LIME,,9.3.1 Interpretable data representation. As it has been mentioned, the black-box model \(f()\) and the glass-box model \(g()\) operate on different data spaces. For example, let us consider a VGG16 neural network (Simonyan and Zisserman 2015) trained on the ImageNet data (Deng et al. 2009).The model uses an image of the size of 244 \(\times\) 244 pixels as input and
