SCIENCE

Exploratory Data analysis ENvironment (EDEN)

The determination of relationships between climate variables and the identification of the most significant associations between them in various geographic regions is an important aspect of climate model evaluation. The EDEN visual analytics toolkit has been developed to aid such analysis by facilitating the assessment of multiple variables with respect to the amount of variability that can be attributed to specific other variables.

ENERGY

Visualizing Energy Resources Dynamically on the Earth (VERDE) ORNL has developed a national visualization and analysis capability for the Department of Energy. This resource will enable real-time status of the electric grid and critical energy sectors to assist federal agencies in their coordination and response during major events such as wide-area power outages, natural disasters and other catastrophic events.



HEALTHCARE

Centers for Medicare & Medicaid Services In 2011 the Centers for Medicare & Medicaid Services (CMS) established an Inter-Agency Agreement (IAA) with the US Department of Energy to enlist the assistance of ORNL in prototyping an agile and cost effective data infrastructure to support future business needs. The collaboration between CMS and CDA has resulted in the design and implementation of an overarching framework prototype, the Knowledge Discovery Infrastructure (KDI). Based on the KDI framework, CDA is now working with Lockheed Martin to establish an advanced data integration and analysis pilot in the CMS Baltimore Data Center.

NATIONAL SECURITY

Piranha Big Data Analytics There is a massive amount of intelligence data available that cannot be manually analyzed. Computers can provide some help in this area, but the shear volumes of data make the most promising approaches impractical. The challenge is for a computer to sift through a large amount of data & provide a human with accurate and relevant information, not to merely allow the analyst to search over an ever increasing set of data.

Oak Ridge Cyber Analytics (ORCA) Oak Ridge Cyber Analytics (ORCA) is a suite of tools for applying automation and advanced analytics to pressing information security problems. ORCA is comprised of several components, each of which addresses widespread technology gaps in computer network defense.

Validating Epidemiological Forecast Models Epidemiological models are widely used as a means to understand disease spread mechanisms and how best to control epidemic outbreaks. A significant challenge within the community is the ability to rigorously verify and validate these models.

BUSINESS INTELLIGENCE

DTHSTR - Personalizing Big Data for Business Intelligence Every person, company, and government organization is faced with continuously flowing, massive streams of data that cannot be manually analyzed. Computers have provided significant help in addressing this problem, but the shear volumes of data have made even the most promising approaches impractical. The Distribute The Highest Selected Textual Recommendation (DTHSTR) engine utilizes advanced analytic technology and a low computing footprint, allowing for analysis of very large and dynamic text data with unprecedented speed and accuracy.
