21. Further Studies of Bootstrap Variability for ROC Analysis on Large Datasets
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7730
Topic: Data and Informatics
Published: 10/11/2010
Authors: Jin Chu Wu, Alvin Martin, Raghu N Kacker
Abstract: The nonparametric two-sample bootstrap is successfully applied to computing the measurement uncertainties in receiver operating characteristic (ROC) analysis on large datasets in areas such as biometrics, speaker recognition system, etc. To determine ...

22. Validation of Two-Sample Bootstrap in ROC Analysis on Large Datasets Using AURC
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7733
Topic: Data and Informatics
Published: 10/11/2010
Authors: Jin Chu Wu, Alvin Martin, Raghu N Kacker
Abstract: Sampling variability can result in uncertainties of measures. The nonparametric two-sample bootstrap method has been used to compute uncertainties of measures in receiver operating characteristic (ROC) analysis on large datasets, such as the standard ...

23. Measurement Uncertainties in Speaker Recognition Evaluation
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7722
Topic: Data and Informatics
Published: 9/15/2010
Authors: Jin Chu Wu, Alvin Martin, Craig Stuart Greenberg, Raghu N Kacker
Abstract: The speaker recognition evaluation is an ongoing series of evaluations conducted by NIST. A detection cost function is computed over the sequence of trials provided and used for all speaker detection tests while measuring speaker detection performanc ...

24. SHREC'10 Track - Range Scan Retrieval
Topic: Data and Informatics
Published: 5/2/2010
Authors: Helin Dutagaci, Afzal A Godil, Chun Pan (Benny) Cheung
Abstract: The SHREC 10 Shape Retrieval Contest of Range Scans aims at comparing algorithms that match a range scan to complete 3D models in a target database. The queries are range scans of real objects, and the objective is to retrieve complete 3D models that ...

25. View subspaces for indexing and retrieval of 3D models
Topic: Data and Informatics
Published: 1/21/2010
Authors: Helin Dutagaci, Afzal A Godil, Bulent Sankur, Yucel Yemez
Abstract: View-based indexing schemes for 3D object retrieval is gaining popularity since they provide good retrieval results. These schemes are coherent with the theory that humans recognize objects based on their 2D appearances. The view-based techniques als ...

26. Climbing Mount Probable: Mutation as a Cause of Nonrandomness in Evolution
Topic: Data and Informatics
Published: 10/1/2009
Author: Arlin B Stoltzfus
Abstract: Genomes differ systematically in Guanine-plus-Cytosine (GC) content. GC-rich genomes encode proteins enriched in amino acids with GC-rich codons, such as Glycine (with codons GGT, GGC, GGA, GGG), while AT-rich genomes are enriched in amino acids wit ...

27. Improving Data Quality in Embedded Sensor Systems for APC
Topic: Data and Informatics
Published: 9/28/2009
Authors: Julien Marc Amelot, YaShian Li-Baboud
Abstract: Achieving next-generation factory (NGF) goals has been an industry challenge for APC applications to acquire a sufficient level of data quality to maximize the benefits of automation. For example, it is difficult to get accurate timestamps because se ...

28. Three Dimensional Shape Retrieval using Scale Invariant Feature Transform and Spatial Restrictions
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7625
Topic: Data and Informatics
Published: 8/20/2009
Author: Lydia Ann Lei
Abstract: Three dimensional shape retrieval is a fairly new concept being studied all over the world. It is notable and essential because it can be applied to multiple disciplines in society, including: computer vision, CAD models, computer graphics, molecular ...

29. A Guide to the RIA Workshop Data Archive
Topic: Data and Informatics
Published: 7/18/2009
Author: Ian M Soboroff
Abstract: During the course of the Reliable Information Access (RIA) workshop, a data archive was created to hold the outputs of the many experiments being done. This archive was designed to serve both as an organizational structure to support the research ...

30. Middleware and Metrology for the Pervasive Future
Topic: Data and Informatics
Published: 7/1/2009
Authors: Antoine Fillinger, Imad Hamchi, Stephane Degre, Lukas Leslaw Diduch, Richard T. Rose, Jonathan G Fiscus, Vincent M Stanford
Abstract: Using data streams from acoustic, video, proximity, location, and even physiological sensors, to recognize user intent and respond appropriately is one of the grand challenges to the multimodal research community. We describe our sensor-net middlewar ...
