演講摘要:
In this talk, I will discuss the fundamentals of the hierarchical modeling technique and some applications in physical sciences and big data analysis, including a fast hierarchical algorithm for evaluating the probabilities and expectations of the p-dimensional truncated multivariate normal distributions. By utilizing the low-rank and low-dimensional structures in the inverse of the covariance matrix, and by processing the compressed information efficiently on a hierarchical tree, the computational complexity of evaluating a p-dimensional integral can be reduced to the asymptotically optimal O(p).
