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.

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.

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

Shapley value: from cooperative game to explainable artificial intelligence
Autonomous Intelligent SystemsWith the tremendous success of machine learning (ML), concerns about their black-box nature have grown. The issue of interpretability affects trust in ML systems and raises ethical concerns such as algorithmic bias.

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 ...

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 ...
