For big data resources to be more than larger haystacks in which to find precious needles, stakeholders will have to aim higher than increasing computing power and producing faster, nimbler machines. ...

Cardiovascular Magnetic Resonance Imaging (CMRI) has become a powerful popular non-invasive tool for detecting biomarkers of various types of subtle pediatric cardiomyopathies yielding BIG temporal, high-resolution data. The complexities associated with the annotation of images and extraction of markers, necessitate the development of efficient workflows to acquire, manage and transform this da...

Analyzing complex online relationships is a difficult job, but new information visualization tools are enabling a wider range of users to make actionable insights from the growing volume of online data. This paper describes the challenges and methods for conducting analyses of threaded conversations such as found in enterprise message boards, email lists, and forums. After defining threaded con...

In this paper, we define a new notion for a clustering to be useful, called actionable clustering. This notion is motivated by applications across various domains such as in business, education, public policy and healthcare. We formalize this notion by adding a novel constraint to traditional unsupervised clustering. We argue that this notion is different from semi-supervised clustering, superv...

A sensor integration framework should be sufficiently general to accurately represent all information sources, and also be able to summarize information in a faithful way that emphasizes important, actionable features. Few approaches adequately address these two discordant requirements. The purpose of this expository paper is to explain why sheaves are the canonical data structure for sensor in...

For decades, companies have embraced technology designed to aid them in strengthening their customer relationships. Traditionally, companies interacted with customers and managed these important relationships via customer relationship management (CRM) systems. But because a plethora of systems used in other parts of the business also contained important customer information, organizations began...

Actionable trading strategies for trading agents determine the potential of the simulated models in real-life markets. The development of actionable strategies is a non-trivial task, which needs to consider real-life constraints and organizational factors in the market. In this paper, we first analyze such constraints on developing actionable trading strategies. Further we propose an actionable...

Ultimately, any business is only as strong as the weakest link in its operational chain. This series has used the concept of the imaging value chain to identify sources of potential weakness and error within the imaging enterprise and then offered practical solutions for remedying those weaknesses to optimize patient care. In this column,we address the endproduct of all radiologic services, the...
