Nettet3. jun. 2024 · The methodology behind Lime is covered in this paper. Currently, Lime helps explain predictions for tabular data, images and text classifiers. Lime basically tries to give a local linear approximation of the model’s behaviour by creating local surrogate models which are trained to mimic the ML model’s predictions locally.

Let’s see how this works: Step 1: Go through all the splits in which the feature was used. Step 2: Measure the reduction in criterion (Gini/information gain) compared to the parent node weighted by the number of samples.

Nettet9.2 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 …
NettetLime is able to explain any black box classifier, with two or more classes. All we require is that the classifier implements a function that takes in raw text or a numpy array and … Nettet4. Explanation Using Lime Image Explainer ¶ In this section, we have explained predictions made by our model using an image explainer available from lime python library. In order to explain prediction using lime, we need to create an instance of LimeImageExplainer. Then, we can call explain_instance() method on it to create an …

In the following tutorial, Natalie Beyer will show you how to use the SHAP (SHapley Additive exPlanations) package in Python to get closer to explainable machine learning results. In this tutorial, you will learn how to use the SHAP package in Python applied to a practical example step by step.
