Data valuation for medical imaging using Shapley value and application to a large-scale chest X-ray dataset [PDF]
Scientific Reports, 2021 The reliability of machine learning models can be compromised when trained on low quality data. Many large-scale medical imaging datasets contain low quality labels extracted from sources such as medical reports.

The Inverse Shapley Value Problem [PDF]
Games and Economic Behavior, 2012 For $f$ a weighted voting scheme used by $n$ voters to choose between two candidates, the $n$ \emph{Shapley-Shubik Indices} (or {\em Shapley values}) of $f$ provide a measure of how much control each voter can exert over the overall outcome of the vote ...

Shapley Value Confidence Intervals for Attributing Variance Explained
Frontiers in Applied Mathematics and Statistics, 2020 The coefficient of determination, the R2, is often used to measure the variance explained by an affine combination of multiple explanatory covariates. An attribution of this explanatory contribution to each of the individual covariates is often sought in

Variance Allocation and Shapley Value [PDF]
Methodology and Computing in Applied Probability, 2017 Motivated by the problem of utility allocation in a portfolio under a Markowitz mean-variance choice paradigm, we propose an allocation criterion for the variance of the sum of $n$ possibly dependent random variables.

The Shapley Value of Phylogenetic Trees [PDF]
Journal of Mathematical Biology, 2007 Every weighted tree corresponds naturally to a cooperative game that we call a "tree game"; it assigns to each subset of leaves the sum of the weights of the minimal subtree spanned by those leaves.

A Shapley Value Approach to Pricing Climate Risks [PDF]
Economics: Journal Articles, 2011 This paper prices the risk of climate change by calculating a lower bound for the price of a virtual insurance policy against climate risks associated with the business as usual (BAU) emissions path. In analogy with ordinary insurance pricing, this price

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 ...

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
