Sparse Inverse Gaussian Process Regression with Application to Climate Network Discovery

Sparse Inverse Gaussian Process Regression with Application to Climate Network Discovery

This video was recorded at NASA Conference on Intelligent Data Understanding (CIDU) 2011, Mountain View, CA. Regression problems on massive data sets are ubiquitous in many application domains including the Internet, earth and space sciences, and finances. Gaussian Process regression is a popular technique for modeling the input-output relations of a set of variables under the assumption that the weight vector has a Gaussian prior. However, it is challenging to apply Gaussian Process regression to large data sets since prediction based on the learned model requires inversion of an order n kernel matrix. Approximate solutions for sparse Gaussian Processes have been proposed for sparse problems. However, in almost all cases, these solution techniques are agnostic to the input domain and do...
