Choquet Integral

The Choquet integral is a powerful nonlinear aggregation function used to combine multiple sources of information, particularly valuable when interactions between data sources are complex and non-additive. Current research focuses on extending its applicability to scenarios with uncertain or incomplete data, including the development of algorithms that handle label uncertainty and bipolar data scales, as well as efficient approximations for high-dimensional applications like interpreting machine learning models (e.g., using Shapley values). This versatile tool finds applications in diverse fields such as sensor fusion, classification, and decision-making, offering improved accuracy and interpretability compared to traditional linear aggregation methods.
