"Each year, the grant support varying numbers of teachers to investigate spreadsheets with the intent of integrating teaching mathematics/science with spreadsheets. These teachers were taught to focus on teaching about ...

The gradient of a velocity vector field is an asymmetric tensor field which can provide critical insight into the vector field that is difficult to infer from traditional trajectory-based vector field visualization techn ...

Many machine learning applications require classifiers that minimize an asymmetric cost function rather than the misclassification rate, and several recent papers have addressed this problem. However, these papers h ...

Sequential supervised learning problems involve assigning a class label to each item in a sequence. Examples include part-of-speech tagging and text-to-speech mapping. A very general-purpose strategy for solving such pro ...

Data structures are more easily understood when they are presented visually rather than textually. We have developed a system, Calypso, to allow the visual definition of data structures programs using pictorial patte ...

Collaborative filtering (CF)-based recommender systems predict what items a user will like or find useful based on the recommendations (active or implicit) of other members of a networked community. In spite of more than ...

This paper studies cluster ensembles for high dimensional data clustering. We examine three different approaches to constructing cluster ensembles. To address high dimensionality, we focus on ensemble construction method ...

We describe the design of a domain-specific language (DSL) for the specification of generic ocean modeling tools, and we describe the implementation of its compiler. The goal of the DSL is to allow the specification of ...

Here is the course assessment form needed for the ABET/CSAB course evaluation notebooks.

End-user programmers’ code (e.g., accountants’ spreadsheet formulas) is fraught with errors. To help mitigate this problem, end-user software engineering research is becoming established. However, most of this work has f ...
