The Cluster Expansion: A Hierarchical Density Model
- 280 Downloads
Density modelling in high-dimensional spaces is a difficult problem. In this paper a new model, called the cluster expansion, is proposed and discussed. The cluster expansion scales well to high-dimensional spaces, and it allows the integrals over model parameters that arise in Bayesian predictive distributions to be evaluated explicitly.
