Explainability metrics are quantitative measures used to evaluate and assess the interpretability of machine learning models. These metrics aim to provide insights into how well a model’s predictions can be understood and trusted by humans. Let’s explore the key concepts, types of explainability metrics, and considerations for quantifying the interpretability of models.

I. Key Concepts:

1. Interpretability vs. Explainability:

• Interpretability refers to the degree to which a human can understand the cause and effect within a system. Explainability is the ability of a model to provide understandable reasons for its predictions. Metrics often address both aspects.

2. Inherent vs. Post hoc Explainability:

• Inherent explainability relates to models that are transparent and interpretable by design (e.g., decision trees). Post hoc explainability involves applying interpretability techniques to complex, black-box models after they have been trained.

3. Simplicity and Transparency:

• Metrics often consider the simplicity and transparency of models. Simpler models and…
