Local Interpretable Model-Agnostic Explanations (LIME) is a tool that can be used to test the interpretability of machine learning models. LIME is based on the idea that a local linear model can approximate any machine learning model. It can be used to explain individual predictions made by a machine learning model.

LIME explanations are used to assess the trustworthiness of a machine learning model and to identify potential issues or biases with its interpretability.

The Purpose of LIME

Local Interpretable Model-Agnostic Explanations provides a way to test the interpretability of machine learning models. LIME is a technique that can be used to explain the predictions of black box machine learning models. It does this by perturbing the input data and observing how the model’s predictions change. This allows us to understand the most important features for the model’s predictions.

Benefits of LIME

Some benefits of using LIME include: 

  • It can be used to test the interpretability of black box machine learning models.
  • It provides a way to understand which features are most important for the model’s predictions.
  • It can be used to create a local interpretable model that can be used to explain the predictions of the black box model.

Applications of LIME Deep Learning

LIME deep learning can be used for any task that can be learned by a deep neural network. Some examples include image classification, object detection, and speech recognition. In general, any task that requires accurate prediction from high-dimensional data can benefit from LIME deep learning.

LIME Best Practices

To ensure that the explanations generated by LIME are reliable and useful, there are certain best practices to follow:


Aim for a reasonable number of iterations when approximating models locally. Too few iterations can provide inaccurate results, while too many may be time consuming or costly from a computational standpoint. 


Take into consideration any biases in data sets used to train the model, as this could affect the accuracy of the local explanations.

Multiple Random Sampling

When possible, sample multiple data segments to better understand how individual features contribute to the model’s predictions. 

Features and Data Set

Make sure all features used in training are relevant and meaningful; otherwise, these features may lead to misleading interpretations of what drives particular decisions.
