Scaling Multidimensional Inference for Structured Gaussian Processes
Gaussian Processes Backfitting Projection Pursuit-Reression Kronecker matrices
2012/11/22
Exact Gaussian Process (GP) regression has O(N^3) runtime for data size N, making it intractable for large N. Many algorithms for improving GP scaling approximate the covariance with lower rank matric...
Scaling properties of first-passage time probabilities in financial markets

2011/9/29
Abstract: Financial markets provide an ideal frame for the study of first-passage time events of non-Gaussian correlated dynamics mainly because large data sets are available. Tick-by-tick data of six...

We show that the `quantum' black hole wave operator in the -Minkowski or bicrossproduct model quantum spacetime introduced in [1] has a natural scaling limit p ! 0 at the event horizon. Here p is t...
