The Choquet integral (ChI) is an aggregation function that is defined with respect to a fuzzy measure (FM). Many ChI-based decision aggregation methods have been proposed to learn the underlying FM. However, FM's boundary and monotonicity constraints have limited the applicability of such methods to decision-level fusion. In a recent work, we removed the constraints on FM to develop a regression model based on the ChI. Our model has a generalized bias that enables capability beyond previously proposed ChI regression approaches. We also developed an approach for learning the parameters of the ChI regression from training data. In this paper, we develop a method to apply ℓ2-regularization on our training algorithm. In our experiments on real-world benchmark data sets, ridge regularized-ChI regression has outperformed the unregularized version in 22 out of 30 (73%) experiments. Also, when compared with several competing regression methods, results show that our approach has superior performance.
