Dependency Modeling

Project Goal

This project addresses the independent assumption issue in fusion process. In the last decade, dependency modeling techniques were developed under a specific distribution of classifiers or by estimating the joint distribution of the posteriors. This project proposes a new framework to model the dependency between features without any assumption on feature/classifier distribution, and overcome the difficulty in estimating the high-dimensional joint density.
