Inherent to the model is a novel Bayesian nonparametric prior that ties and shrinks parameters in a powerful way. We develop theory about the model's infinite limit and its steady-state. The model's inductive bias is demonstrated on a variety of real-world datasets where it is shown to learn interpretable structure and have superior predictive performance.}, url = {http://approjects.co.za/?big=en-us/research/publication/poisson-gamma-dynamical-systems/}, }
