+
+Extending Variational Inference (VI), an approximate bayesian inversion method,
+to hybrid models, i.e. models that combine mechanistic and machine-learning parts.
+
+The model inversion, inferes parametric approximations of posterior density
+of model parameters, by comparing model outputs to uncertain observations. At
+the same time, a machine learning model is fit that predicts parameters of these
+approximations by covariates.
