talk: Martineau on domain adaptation for sentiment analysis

CSEE Colloquium

Identifying and Isolating Text Classification Signals from
Domain and Genre Noise for Sentiment Analysis

Justin Martineau
Computer Science and Electrical Engineering
University of Maryland, Baltimore County

1:00pm Friday 4 November 2011, ITE 227

Justin Martineau will describe the results of his PhD dissertation which he will defend later this month. His dissertation research makes both algorithmic and theoretical contributions to the fields of domain adaption and sentiment analysis. First, it provides algorithms to discover and weight discriminative classification task specific features within a domain. Second, it produces algorithms to score how well these features transfer to a new target domain. Third, it lays out a general theory for the kinds of information and the types of noise they produce that exist in text classification tasks. Finally, the dissertation presents a definition of domain independence and a statistical description of it. The research offers readers a firm theoretical foundation as well as practical algorithms when implementing any of the motivating examples and for future research in the field.

Adapt3D: A Framework for Supporting CFD and MHD Modeling

Professor John E. Dorband
Research Associate Professor and MCC Chief Scientist
Computer Science and Electrical Engineering
University of Maryland, Baltimore County

1:00pm Friday 21 October 2011, ITE227

Adapt3D is a software framework that supports 3-D computational fluid dynamics (CFD) and magnetohydrodynamics (MHD) modeling on an unstructured mesh. It facilitates adaptive refinement and execution in a parallel computing environment, either on shared memory or distributed memory computer architectures. The framework was designed primarily to support parallel computing of simulations on a continuum expressed by an adaptively refined unstructured mesh. It was designed to cleanly differentiate the code that manages an unstructured mesh on a parallel computer and the code that performs the numerics on the components of the mesh. The intent is to ease the burden of the engineer or scientist when it come to understanding parallel computing or adaptive refinement, allowing him to spend his time understanding the computational science rather than the computer science.

Dr. John Dorband received a BA in Math and Physics from Northwest Nazarene University in 1972 and a PhD in Computer Science from The Pennsylvania State University in 1985. He work for NASA for 21 years doing research in parallel and high performance hardware architectures and software. He has developed parallel compilers, algorithms and applications. He was a member of the group that developed the concept of developing high performance computing architectures from commodity components (the Beowulf project).

EE Graduate Seminar

Detection and Classification of Chemical, Biological, and Explosive
Materials: A Brief Overview of Several Cutting-Edge Problem Areas

Darren Emge
PI and Deputy Branch Chief
Laser Standoff Detection Branch
US Army Edgewood Chemical Biological Center

11:30am-12:45pm Friday, 21 October 11, ITE 231

The detection and classification of chemical, biological, and explosive (CBE) materials is an area of extremely active research. With the advent of new sensor technologies and sensing methods there is the rapidly growing need for timely robust detection and classification algorithms. Several factors associated with emerging sensors offer novel challenges for the signal processing community. As sensor platforms become more mobile the added complexities of "on the move" standoff detection requires the use of non-stationary and adaptive methods. Ever increasing overall sensitivity introduces variations in signal response and many methods currently lack adequate performance models or ground truth. Reduction in size, weight, and power, along with real time performance, further limit approaches that can be used in addressing these issues. This presentation will provide a brief overview of several of these cutting edge problem areas and offer a glimpse into this challenging problem space.

Mr. Darren Emge earned a BS in Physics from UMBC in 1992. He then went to work for the University of Maryland Medical System, Department of Neurology. During his time at University Medical System, he developed analysis algorithms for evoked response potentials (ERP), functional magnetic resonance (fMRI), or neuronal mapping. He also supported the cognitive psychology group in the development of a pupil motion tracking system in the study of dyslexia. Mr. Emge earned the MSEE from UMBC/CSEE Dept in 2000. In 2001 He joined the US Army ECBC passive detection team investigating advanced mathematical techniques for the detection of chemical vapors based on Fourier transform infrared (FTRI) imaging. In 2003 Mr. Emge was promoted to a Principal Investigator (PI) in the laser standoff detection branch, where he currently serves as PI and Deputy Branch Chief. His current work is in the areas of the detection of small signals, detection of non-stationary signals, and the application of non-linear signal processing methods for the detection of biological and trace chemical/explosive materials.

Prof. Lomonaco talks on Quantum Knots, Quantum Braids and Quantum Computing

CSEE processor Samuel J. Lomonaco is giving a talk on his research on quantum computing as part of the Joint Quantum Institute seminar series sponsored by UMCP and NIST. The talk will be given at 12:30pm Monday 17 October, in room 1201 in the Physics building at College Park.

Quantum knots and quantum braids: Their possible application to superfluid vortices and to topological quantum computing in optical lattices.

In this talk, we show how to reconstruct knot theory in such a way that it is intimately related to quantum physics. In particular, we give a blueprint for creating a quantum system that has the dynamic behavior of a closed knotted piece of rope moving in 3-space. Within this framework, knot invariants become physically measurable quantum observables, knot moves become unitary transformations, with knot dynamics determined by the Schroedinger equation. The same approach can also be applied to the theory of braids. Toward the end of the talk, we look at possible applications to superfluid vortices and to topological quantum computing in optical lattices.

For more information, see the entry on the Joint Quantum Institute calendar.

Yordan Kostov, PhD
Research Associate Professor
UMBC Center for Advanced Sensor Technology

11:30am-12:45pm, Friday 14 October 2011, ITE 231

Interaction of the light with the matter is one of the fundamental interactions in the nature. It is used in a variety of fields, stretching from telecommunications to life sciences. In this talk, the use of luminescence for sensing purposes will be highlighted. In particular, fluorescence spectroscopy will be illustrated. Multiple examples that employ different characteristics of the fluorescence (excitation and emission spectrum, decay time, polarization, and combination thereof) will be given. The presented sensing principles are used for measurements of oxygen, pH, CO2, ethanol, etc. As an optical chemical sensor requires successful interweaving of elements from 5 different scientific areas (analytical chemistry, polymer science, optics, electronics and computer science), the problems and the requirements for system integration are discussed.

Dr. Yordan Kostov received his B.Sc. and M.Sc. with honors in 1987 from Department of Electrical Engineering, Odessa Politechnic Institute, Former USSR. He received a Ph.D. Degree in Electrical/Chemical Engineering from Bulgarian Academy of Sciences for his work in the area of optical chemical sensors and biosensors.

CSEE Colloquium

Integrated Lifecycle of IT Services in Cloud Environments

Karuna Pande Joshi
University of Maryland, Baltimore County

1:00pm Friday 7 October 2011, ITE 227, UMBC

Virtualized service models are now emerging and redefining the way information technology (IT) is delivered. Managing these services efficiently over the cloud is an open challenge. For my PhD dissertation research, I have proposed a semantically rich, policy-based framework to automate the lifecycle of cloud services.  In this talk, I will describe the proposed methodology for the lifecycle of IT services delivered on the cloud.  I have divided the IT service lifecycle into five phases of requirements, discovery, negotiation, composition, and consumption and will detail each phase and list the high level ontologies that I have developed for them.  This research complements previous work on ontologies for service descriptions in that it goes beyond simple matchmaking and is focused on supporting negotiation for the particulars of IT services.  I will also describe the web-based prototype system that we are developing in collaboration with NIST. We are using Semantic Web technologies to represent and reason about services and service requirements.

Karuna P Joshi is a Ph.D. student in the computer Science and Electrical Engineering Department and an IT Project Manager with over 15 years of industrial experience.

talk: Beyond Reactive Management of Network Intrusions, Noon 10/12 ITE456

Department of Information Systems Colloquium

Beyond Reactive Management of Network Intrusions

Professor Sushil Jajodia
Center for Secure Information Systems
George Mason University

12:00pm Wednesday, 12 October 2011, ITE456, UMBC

This talk will discuss issues and methods for survivability of systems under malicious attacks. To protect from such attacks, it is necessary to take steps to prevent attacks from succeeding. At the same time, it is important to recognize that not all attacks can be averted at the outset; attacks that are successful to some degree must be recognized as unavoidable and comprehensive support for identifying and responding to attacks is required.

In my talk, I will describe the recent research on attack graphs that represent known attack sequences attackers can use to penetrate computer networks. I will show how attack graphs can be used to compute actual sets of hardening measures that guarantee the safety of given critical resources. Attack graphs can also be used to correlate received alerts, hypothesize missing alerts, and predict future alerts, all at the same time. Thus, they offer a promising solution for administrators to monitor and predict the progress of an intrusion, and take appropriate countermeasures in a timely manner.

I will conclude my talk with a demo of the working system.

Sushil Jajodia is University Professor, BDM International Professor, and the director of Center for Secure Information Systems in the Volgenau School of Engineering at the George Mason University, Fairfax, Virginia. He served as the chair of the Department of Information and Software Engineering during 1998-2002.
