State estimation in nonlinear and non-Gaussian systems represents one of the most complex challenges in the field of dynamic modeling and Bayesian inference. Traditionally, methods such as the extended Kalman filter or particle filters offer solutions, but they present limitations in terms of scalability, accuracy, or computational requirements. In this context, a novel approach based on a variational Lagrangian formulation allows reinterpreting inference as a sequence of entropic trust-region updates, subject to dynamic consistency constraints. This framework gives rise to a family of forward-backward algorithms that, by employing Gauss-Markov approximations, achieve favorable computational complexity even in scenarios with severe nonlinearities and non-Gaussian distributions. The key lies in the use of generalized statistical linear regression and Fourier-Hermite moment matching to close the recurrences, combining numerical robustness with efficiency.
From a practical perspective, this technique opens new possibilities in areas such as robotics, autonomous navigation, financial time series analysis, and industrial process monitoring. Companies seeking to implement custom application solutions for control or prediction systems can benefit from this paradigm, as it allows integrating complex state models with minimal information loss. Furthermore, the ability to handle non-Gaussian uncertainties is especially valuable in contexts where data presents outliers or multimodal distributions, as occurs in industrial sensors or biomedical signals. Combining this type of inference with artificial intelligence services for businesses, such as those offered by Q2BSTUDIO, enhances the creation of adaptive and robust systems capable of operating in real time.
