How Shapley Values Work - A Simple Guide

⚠️REMEMBER THIS A RANDOM MODEL ⚠️, it’s not real life, here we can see that higher “Deuda” values make the contribution of the variable “negative”, i.e., close to

§Consider model behavioras profit §E.g., the prediction, the loss, etc. §Then, use Shapley values to quantify each feature’s impact 22 ©2022 Su-In Lee SHAP §SHAP = SHapleyAdditive

Making your model confesses: Shapley values

Shapley values quantify the contributions of input features in a model’s predictions. They enable practitioners to evaluate feature importance effectively, particularly in regression

Shapley values are a widely used approach from cooperative game theory that come with desirable properties. This tutorial is designed to help build a solid understanding of how to

Shapley values stand out as a powerful tool in the realm of machine learning, bridging the gap between complex model predictions and human understanding. By assessing

Visualizing SHAP Values for Model Explainability

Using this example as it relates to models — your friends are like features or inputs in a model, the total profit is the model’s prediction and each friend’s share of the profit represent the

The first time I heard about Shapley values was when I was reading up on model interpretability. I came across SHAP, a framework for better understanding why your machine

Exploring the mechanics of the SHAP feature attribution method with toy examples. Presentation of Shapley values.

SHAP (Shapley Additive Explanations) is a popular technique for this. It provides insights into how much each feature in a dataset contributes to a particular prediction, making complex models more understandable and

I am starting here a series of posts where I will share with you some ways you can achieve different levels of interpretability from your models and make them confess. Today I will

Shapley values can help reduce bias in machine learning models in several ways. First, they can help identify which features are contributing to bias, this allows us to remove or

Whether you’re optimizing for model performance, reducing costs in data acquisition, or ensuring fairness and ethical decision-making in your models, Data Shapely

You can read my second post “Explain Any Models with the SHAP Values — Use the KernelExplainer”, in which I show that if your model is a tree-based machine learning model, you should use the

In this post, we’ll dive a level deeper and explore the concept of the Shapley value. Many popular explanation techniques – such as QII and SHAP – all make use of Shapley values in their computations. So what is the Shapley

Shapley值给了一个理论基础扎实的重要性定义，但是Shapley值的计算一直是一个很大的问题（指数级复杂度），这也带来了很大的限制。我们通过将Shapley值直接作为神经网络的中层特征

The Shapley value is the average contribution of a feature value to the prediction in different coalitions. The Shapley value is NOT the difference in prediction when we would

As a result, many popular explanation techniques make use of the Shapley value to interpret ML models. In this blog post, we outlined the theoretical intuition behind the

The first time I heard about Shapley values was when I was reading up on model interpretability. I came across SHAP, a framework for better understanding why your machine

Explainable AI is a key concept in Machine Learning/AI to explain why your model is making the predictions. It helps us understand how good a model is. In this blog, we cover how you can

Like Shapley values, Owen values aim to fairly distribute the model’s prediction among features. 3 However, instead of evaluating features individually, Owen values allow us
