Towards a Domain-Specific Framework for Predictive Analytics in Manufacturing

October 3, 2014
Author(s)
David J. Lechevalier, Anantha Narayanan Narayanan, Sudarsan Rachuri
Data analytics is proving to be very useful for achieving productivity gains in manufacturing. Predictive analytics (using advanced machine learning) is particularly valuable in manufacturing, as it leads to production improvement with respect to the cost

On Run Diversity in "Evaluation as a Service"

July 6, 2014
Author(s)
Ellen M. Voorhees
"Evaluation as a service" (EaaS) is a new methodology that enables community-wide evaluations and the construction of test collections on documents that cannot be distributed. The basic idea is that evaluation organizers provide a service API through which

The Effect of Sampling Strategy on Inferred Measures

July 6, 2014
Author(s)
Ellen M. Voorhees
Using the inferred measures framework is a popular choice for constructing test collections when the target document set is too large for pooling to be a viable option. Within the framework, different amounts of assessing effort is placed on different

Persistence-based Structural Recognition

June 28, 2014
Author(s)
Chunyuan Li
This paper presents a framework for object recognition using topological persistence. In particular, we show that the so-called persistence diagrams built from functions defined on the objects can serve as compact and informative descriptors for images and

SHREC14 Track: Extended Large Scale Sketch-Based 3D Shape Retrieval

June 12, 2014
Author(s)
Afzal A. Godil, Chunyuan Li
Large scale sketch-based 3D shape retrieval has received more and more attentions in the community of content- based 3D object retrieval. The objective of this track is to evaluate the performance of different sketch-based 3D model retrieval algorithms

SHREC14 Track: Large Scale Comprehensive 3D Shape Retrieval

June 12, 2014
Author(s)
Afzal A. Godil, Chunyuan Li
The objective of this track is to evaluate the performance of 3D shape retrieval approaches on a large-sale com- prehensive 3D shape database which contains different types of models, such as generic, articulated, CAD and architecture models. The track is

SHREC14 Track: Retrieval and classification on Textured 3D Models

June 12, 2014
Author(s)
Afzal A. Godil
This contribution reports the results of the SHREC 2014 track: Retrieval and classification on textured 3D models, whose goal is to evaluate the performance of retrieval algorithms when models vary either by geometric shape or texture, or both. The

SHREC14 Track: Shape Retrieval of Non-Rigid 3D Human Models

June 12, 2014
Author(s)
Afzal A. Godil, Chunyuan Li
We have created a new benchmarking dataset for testing non-rigid 3D shape retrieval algorithms, one that is much more challenging than existing datasets. Our dataset features exclusively human models, in a variety of body shapes and poses. 3D models of

Content-Based Video Copy Detection Benchmarking at TRECVID

June 1, 2014
Author(s)
George M. Awad, Paul D. Over, Wessel Kraaij
This paper presents an overview of the video copy detection benchmark which was run over a period of 4 years (2008-2011) as part of the TREC Video Retrieval (TRECVID) workshop series. The main contributions of the paper include i) an examination of the

Stochastic Modeling and Simulation of Marginally Trapped Neutrons

May 20, 2014
Author(s)
Kevin J. Coakley
For a magnetic trapping experiment, I present an efficient method for simulating experimental beta −decay rates which accounts for loss of marginally trapped neutrons due to wall collisions and other possible loss mechanisms. Monte Carlo estimates of time

TRECVID 2013 -- An Overview of the Goals, Tasks, Data, Evaluation Mechanisms, and Metrics

May 5, 2014
Author(s)
Paul D. Over, Jonathan G. Fiscus, Gregory A. Sanders, David M. Joy, Martial Michel, George M. Awad, Alan Smeaton, Wessel Kraaij, Georges Quenot
TRECVID 2013 was a TREC-style video analysis and retrieval evaluation, the goal of which remains to promote progress in content-based exploitation of digital video via open, metrics-based evaluation. Over the last ten years this effort has yielded a better

Machine Learning Analysis for Identification of Cell Shape Metrics Associated with Stem Cell Differentiation in Nanofiber Scaffolds

April 19, 2014
Author(s)
Desu Chen, Sumona Sarkar, Stephen J. Florczyk, Subhadip Bodhak, Carl G. Simon Jr., Joy P. Dunkers, Julian Candia, Wolfgang Losert
Cell shape has been demonstrated to be closely related to cell function and may be an important predictor of cell fate. Many metrics are available to describe cell shape, however the relationship of these metrics to cell fate are not well understood

Performance Testing and Evaluation of Transformative Apps Devices

April 16, 2014
Author(s)
Anthony J. Downs, Lisa J. Fronczek, Emile L. Morse, Brian A. Weiss, Ian P. Bashor, Craig I. Schlenoff
Transformative Apps (TransApps) is a Defense Advanced Research Projects Agency (DARPA) funded program whose goal is to develop a range of militarily-relevant software applications ("apps") to enhance the operational effectiveness of military personnel on

Building Better Search Engines by Measuring Search Quality

March 3, 2014
Author(s)
Ellen M. Voorhees, Paul D. Over, Ian Soboroff
Search engines help users locate particular information within large stores of content developed for human consumption. For example, users expect web search engines to direct searchers to web sites based on the content of the site rather than the site

Optimal Spread in Network Consensus Models

January 27, 2014
Author(s)
Fern Y. Hunt
Suppose we seek a set of nodes in a network that will enable the fastest spread of information in a decentralized communication environment. If communication resources are limited there are constraints on the number of nodes that can be selected. In this

A comparison of methods for sketch-based 3D shape retrieval

December 13, 2013
Author(s)
Afzal A. Godil
Sketch-based 3D shape retrieval has become an important research topic in content-based 3D object retrieval. To foster this research area, two Shape Retrieval Contest (SHREC) tracks on this topic have been organized by us in 2012 and 2013 based on a small
