Estimating Fault Detection Effectiveness

April 1, 2014
Author(s)
David R. Kuhn, Raghu N. Kacker, Yu Lei
[Poster] A t-way covering array can detect t-way faults, however they generally include other combinations beyond t-way as well. For example, a particular test set of all 5-way combinations is shown capable of detecting all seeded faults in a test program

Bootstrap Variability Studies in ROC Analysis on Large Datasets

March 19, 2014
Author(s)
Jin Chu Wu, Alvin F. Martin, Raghu N. Kacker
The nonparametric two-sample bootstrap is employed to compute uncertainties of measures in receiver operating characteristic (ROC) analysis on large datasets in areas such as biometrics, and so on. In this framework, the bootstrap variability was

Fault Localization Based on Failure-Inducing Combinations

November 7, 2013
Author(s)
Raghu N. Kacker
Combinatorial testing has been shown to be a very effective testing strategy. After a failure is detected, the next task is to identify the actual fault that causes the failure. In this paper, we present an approach to fault localization that leverages the

CCM: A Tool for Measuring Combinatorial Coverage of System State Space

October 10, 2013
Author(s)
Itzel Dominguez, D. Richard Kuhn, Raghu N. Kacker, Yu Lei
This poster presents some measures of combinatorial coverage that can be helpful in estimating residual risk related to insufficient testing of rare interactions, and a tool for computing these measures.

Measurement Uncertainty in Cell Image Segmentation Data Analysis

August 13, 2013
Author(s)
Jin Chu Wu, Michael W. Halter, Raghu N. Kacker, John T. Elliott, Anne L. Plant
Cell image segmentation is a part of quantitative studies regarding cell movement and cell behavior, and it plays a critical role in molecular biology and cellular biochemistry. Therefore, it is fundamentally important to evaluate the performance levels of

Significance Test with Data Dependency in Speaker Recognition Evaluation

July 25, 2013
Author(s)
Jin Chu Wu, Alvin F. Martin, Craig S. Greenberg, Raghu N. Kacker, Vincent M. Stanford
To evaluate the performance of speaker recognition systems, a detection cost function defined as a weighted sum of the probabilities of type I and type II errors is employed. The speaker datasets may have data dependency due to multiple uses of the same

ISO/IEEE 11073 Personal Health Data (IEEE 11073 PHD) is a set of standards that addresses the interoperability of personal healthcare devices. As an important part of IEEE 11073 PHD, ISO/IEEE 1107-20601 optimized exchange protocol (IEEE 11073-20601)

ACTS: A Combinatorial Test Generation Tool

March 22, 2013
Author(s)
Raghu N. Kacker
In this paper, we introduce a combinatorial test generation tool called Advanced Combinatorial Testing System (or ACTS). ACTS supports t-way combinatorial test generation with several advanced features such as mixed-strength test generation and constraint

An Input Space Modeling Methodology for Combinatorial Testing

March 22, 2013
Author(s)
Mehra N. Borazjany, Laleh Ghandehari, Yu Lei, Raghu N. Kacker, D. Richard Kuhn
The input space of a system must be modeled before combinatorial testing can be applied to this system. The effectiveness of combinatorial testing to a large extent depends on the quality of the input space model. In this paper we introduce an input space

Applying Combinatorial Testing to the Siemens Suite

March 22, 2013
Author(s)
Laleh Ghandehari, Mehra N. Borazjany, Yu Lei, Raghu N. Kacker, D. Richard Kuhn
Combinatorial testing has attracted a lot of attention from both industry and academia. A number of reports suggest that combinatorial testing can be effective for practical applications. However, there still seems to lack systematic, controlled studies on

Combinatorial Coverage Measurement Concepts and Applications

March 22, 2013
Author(s)
David R. Kuhn, Itzel (. Dominquez Mendoza, Raghu N. Kacker, Yu Lei
Empirical data demonstrate the value of t-way coverage, but in some testing situations, it is not practical to use covering arrays. However any set of tests covers at least some proportion of t-way combinations. This paper describes a variety of measures

Author(s)
Ruth L. Jacobsen, Karl K. Irikura, Russell D. Johnson III, Raghu N. Kacker
Anharmonic calculations using vibrational perturbation theory are known to provide near-spectroscopic accuracy when combined with high-level ab initio potential energy functions. However, performance with economical, popular electronic structure methods is
