It is well-known that forests play a vital role in maintaining biodiversity and the
health of ecosystems across the Earth. This important ecological resource is under threat from
both anthropogenic and biogenic pressures, ranging from insect infestations to commercial logging. Detecting, quantifyi ...

Earth science data consists of a strong seasonality component as indicated by the
cycles of repeated patterns in climate variables such as air pressure, temperature and precipitation. The seasonality forms the strongest signals in this data and in order to nd other patterns, the seasonality is remo ...

Statistical downscaling is commonly used in climate modeling to obtain high-resolution
spatial projections of future climate scenarios from the coarse-resolution outputs projected by
global climate models. Unfortunately, most of the statistical downscaling approaches using standard regression method ...

The increase in demand for air traffic over the past several years has been accompanied by increased delays in the National Airspace System (NAS). The main causes of these delays have been weather and traffic volume, especially near airports. In this talk, I will use examples drawn from airport surf ...

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 ve ...

We describe the development of a system for an automated, iterative, real‐time classification of transient events discovered in synoptic sky surveys. The system under development incorporates a number of Machine Learning techniques, mostly using Bayesian approaches, due to the sparse nature, heterog ...

This paper takes an empirical approach to identify operational factors at busy airports that may
predate go-around maneuvers. Using four years of data from San Francisco International Airport, we begin our investigation with an analysis of sequence of landing aircraft that may increase the probabili ...
