Artificial Intelligence (AI) has made incredible strides, but understanding how and why AI systems make decisions is still challenging. That’s where SHAP (SHapley Additive exPlanations) comes in. This innovative approach to explainable AI enables users to uncover the intricate workings of AI models and develop ethical systems that are explainable, equitable, and reliable.

In this blog post, we’ll explore the significance of SHAP-explainable AI for model interpretability and how it promotes transparency in AI development, all in a way that’s easy to understand.

What is SHAP

SHAP-explainable AI (also known as SHapley Additive exPlanations) is an open-source algorithm that enables model interpretability by providing visual explanations of individual predictions. The framework explains how each feature contributes to the prediction, making it easier to identify areas of potential bias in automated decision-making systems. 

This makes SHAP a powerful tool for detecting unfairness and improving transparency in machine learning models.

Demystifying AI with SHAP

Artificial intelligence (AI) models are often considered enigmatic or “black boxes” operating in mysterious ways. However, breakthroughs such as SHAP provide a framework for understanding how these models work. SHAP utilizes game theory principles to assign a contribution to each feature, making the decision-making process more transparent. 

By analyzing individual features’ impact, SHAP provides advanced insight into the decision-making process of AI models.

Understanding the Logic of SHAP

The SHAP approach assigns a score to each feature, called the Shapley value, by assessing its significance in the prediction process. This value depicts the average contribution of a feature in collaboration with other features. In simple terms, it measures the impact of each feature when combined with various others in the prediction process.

To calculate the Shapley value, SHAP considers all possible permutations of features and evaluates their contributions. For each permutation, it systematically determines the marginal contribution of each feature by comparing the model’s predictions when the feature is included or excluded.
