What is the Explanation (technique)?

There are six broad approaches as it relates to post-hoc explainability.

• Feature relevance: These approaches to explainability focus on the inner functioning of the model and highlight the features that best explain the outcome of the model.
• Model simplification: These approaches focus on building a new model that is a simplification of a more complex model that is to be explained.
• Local explanations: These approaches segment the solutions space and provide explanations for smaller segments that are less complex.
• Explanations by example
• Visualization
• Text explanations
