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 ...

Many processes in atmosphere-ocean science develop multiscale temporal and spatial
patterns, with complex underlying dynamics and time-dependent external forcings. Because of the possible advances in our understanding and prediction of climate phenomena, extracting that variability empirically from ...

An analysis of the role that the ontology plays in determining verb meaning and semantic roles is presented. The discussion will contrast the current approaches to semantic role labeling using supervised machine learning methods to semantic approaches that rely on the ontology and verb sub-categoriz ...

There is increasing pressure on the science community not only to understand how recent and projected changes in climate are likely to impact our global environment and the natural resources on which we depend, but also to design solutions to mitigate or cope with the likely impacts. Responding to t ...

A fundamental problem for analysis of multidimensional text databases is efficient
and effective support of various kinds of online applications, such as summarizing the content
of text cells and comparing the contents across multiple text cells. In this paper, we propose
a new infrastructure called ...

Ecosystem-related observations from remote sensors on satellites oer significant possibility for understanding the location and extent of global land cover change. In this paper, we focus on time series segmentation techniques in the context of land cover change detection. We propose a model-based t ...

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 ...

Pressure dipoles in global climate data capture recurring and persistent, large-scale
patterns of pressure and circulation anomalies that span distant geographical areas (teleconnections). In this paper, we present a novel graph based approach called shared reciprocal nearest neighbors that conside ...

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 ...
