The Shapley Value of Tuples in Query Answering [PDF]
Logical Methods in Computer Science, 2021 We investigate the application of the Shapley value to quantifying the contribution of a tuple to a query answer. The Shapley value is a widely known numerical measure in cooperative game theory and in many applications of game theory for assessing the ...

A comparative study of methods for estimating model-agnostic Shapley value explanations [PDF]
Data mining and knowledge discovery, 2023 Shapley values originated in cooperative game theory but are extensively used today as a model-agnostic explanation framework to explain predictions made by complex machine learning models in the industry and academia.

Alternative Axiomatic Characterizations of the Grey Shapley Value [PDF]
International Journal of Supply and Operations Management, 2014 The Shapley value, one of the most common solution concepts of cooperative game theory is defined and axiomatically characterized in different game-theoretic models.

Shapley Values for Feature Selection: The Good, the Bad, and the Axioms
IEEE Access, 2021 The Shapley value has become popular in the Explainable AI (XAI) literature, thanks, to a large extent, to a solid theoretical foundation, including four “favourable and fair” axioms for attribution in transferable utility games.

Item-based recommendation with Shapley value [PDF]
EAI Endorsed Transactions on Context-aware Systems and Applications, 2019 Discovering knowledge in archival data is the goal of researchers. One of them is collaborative filtering recommender system is developing fastly today. It may be rather effective in sparse and "long tail" datasets. Calculating to make decision

The shapley value of age-period-cohort effects
Journal of Applied Economics, 2021 The exact linear dependency among age, period and birth cohort makes it impossible to recover the true parameters of Age-Period-Cohort (APC) models. We then propose to extract reliable information from APC models via the Shapley decomposition, a model ...

When is Shapley Value Computation a Matter of Counting? [PDF]
Proc. ACM Manag. Data, 2023 The Shapley value provides a natural means of quantifying the contributions of facts to database query answers. In this work, we seek to broaden our understanding of Shapley value computation (SVC) in the database setting by revealing how it relates to ...

DU-Shapley: A Shapley Value Proxy for Efficient Dataset Valuation [PDF]
Neural Information Processing Systems, 2023 We consider the dataset valuation problem, that is, the problem of quantifying the incremental gain, to some relevant pre-defined utility of a machine learning task, of aggregating an individual dataset to others.

Some Properties of Interval Shapley Values: An Axiomatic Analysis
Games, 2023 Interval games are an extension of cooperative coalitional games, in which players are assumed to face payoff uncertainty. Characteristic functions thus assign a closed interval instead of a real number.

Shap-CAM: Visual Explanations for Convolutional Neural Networks based on Shapley Value [PDF]
European Conference on Computer Vision, 2022 Explaining deep convolutional neural networks has been recently drawing increasing attention since it helps to understand the networks' internal operations and why they make certain decisions.
