About Julia

When did you become interested in Computer Science? After my freshman year at UMBC. I was a CMPE major for my first year, but I decided that I enjoyed CMSC more.

What area of Computer Science interests you the most? I just really love writing code.

What are your plans after graduation? I plan to get a job in the industry, possibly a defense contractor position. 

What is your dream job? Any job that lets me be creative with my coding and gives me interesting problems to solve.

About being a CS major

Who is your favorite professor or course? Dr. Park is an amazing professor. He's really great about making his subject matter interesting, no matter what class he's teaching.

Are you part of any on-campus clubs, organizations, teams, or labs?  I'm an active member of Humans versus Zombies club.

What is the best part about being a CWIT Scholar/ Affiliate? The support network. I don't know how I would've gotten as far as I have without their help.

What advice would you give to other females entering the field? Adversity toward women in computer science has really died down, and there are a lot of support groups out there for women in technology now. That doesn't mean you'll never encounter adversity, but it does mean that you can do something about it, and there are lots of people–like those at CWIT–who will be glad to help you.

What advice would you give to incoming students? Get plenty of sleep!

About life at UMBC

What is the best part about campus life at UMBC? Everything is within a few minutes walking distance. That means you don't have to get up really early to get to class, you can go get food between classes without being late, and you can grab a bunch of people and go to late night at the dining hall.

What is your favorite spot on campus? The commuter lounge in the Commons is almost always full of cool people. It's a great place to hang out between classes.

Where can you get the best coffee/lunch/ food or beverage of choice? The sandwich shop in the Administration building probably has the best lunch-type food. The Skylight lounge is another often-overlooked place with really good food, too.

UMBC CSEE Colloquium

Advanced Computer Systems (ACS)
Machine Learning program

Mark McLean
Senior Researcher, Advanced Computer Systems group

1:00pm Friday, 30 November 2012, ITE 227, UMBC

My talk will discuss the ACS Machine learning program. The ACS ML program's focus is on three main areas; algorithm development, applied research and integration into efficient hardware. Our algorithm development work has created the Concurrent Learning Algorithm and Importance Map technologies. These technologies were developed in-house and have some unique capabilities which make it ideal for our purposes. I'll give some demos of these technologies learning on datasets from the UCI repository. For our current research effort, I will discuss our ideas of using neural networks to process complex digital algorithms, which is not a traditional focus for neural networks. Here, I will discuss our efforts to make a neural network learn the Advanced Encryption Standard encryption functionality and why this could impact the way we design digital systems in the future. For our hardware focus, I'll talk about our efforts to develop a Memristor-based neuromorphic processor and why we hope to succeed where others have failed.

Mark McLean has been a senior researcher in the Advanced Computer Systems group Since 2009. His main area of research is on neural network algorithms, application and neuromorphic processor development. Mr. McLean has done post-graduate work at UMD, Holds a MS degree in Computer Engineering from Loyola College and a BS degree in Computer Science. Previously, he held the position of technical director for the microelectronics and reverse engineering group in the DOD. He has work in industry as lead designer for re-configurable computing at Annapolis Micro-Systems and is a retired officer from the USAF.

Subjectivity and Social Role Recognition in Meetings

Theresa A. Wilson
Human Language Technology Center of Excellence
Johns Hopkins University

12 noon-1pm, Tue. 20 Nov. 2012, ITE459

Opinions, sentiments and other types of subjective content are an important part of any meeting. Meeting participants express pros and cons about ideas, they support or oppose decisions, and they make suggestions that may or may not be adopted. In this talk, I will present an annotation scheme for labeling subjective content in meetings, as well as experiments for recognizing subjective utterances and their polarity. Our experiments show that even very shallow linguistic features, such as n-grams of characters, can be effective for this task, and that the combination of classifiers using word, character, and phoneme n-grams yields the best result for subjective utterance recognition. Finally, I will discuss the application of subjectivity recognition to social role recognition in meetings.

Theresa Wilson is a research scientist working on opinion and sentiment analysis at the Johns Hopkins Human Language Technology Center of Excellence (HLTCOE). Before coming to Johns Hopkins, she completed her post-doctoral research as part of the AMIDA Project (www.amiproject.org) at the University of Edinburgh Human Communication Research Centre.

Data Intensive Scientific Compute Model for Multicore Clusters

Phuong Nguyen

10:00am 21 November 2012, ITE 325B

Data intensive computing holds the promise of major scientific breakthroughs and discoveries from the exploration and mining of the massive data sets becoming available to the science community. This expectation has led to tremendous increases in data intensive scientific applications. However, data intensive scientific applications still face severe challenges in accessing, managing and analyzing petabytes of data. In particular, workflow systems to support such scientific applications are not as efficient when dealing with thousands and even more of complex tasks within jobs that operate across high performance large multicore clusters with very large amounts of streaming data. Scheduling, it turns out, is an integral workflow component in the execution often of thousands or more tasks within a data intensive scientific application as well as in managing  the access and flow of many jobs to the available resource environment. Recently, MapReduce systems such as Hadoop, have proven successful for many business data intensive problems. However, there are still many limitations in the use of MapReduce systems for data-intensive scientific problems mainly because they do not support the characteristics of science such as data formats, specialized data analytic tools (e.g. math libraries), accuracies, and interfaces with non MapReduce components.

This thesis addresses some of these limitations by proposing a MapReduce workflow model and its runtime system using Hadoop for orchestrating MapReduce jobs for data intensive scientific workflows. Novel heuristic based scheduling algorithm is proposed in the workflow system to manage the parallel execution of data intensive scientific applications. This thesis has developed a hybrid MapReduce scheduling algorithm based on dynamic priorities, proportional resource sharing techniques that reduce delays for variable length concurrent tasks, and takes advantage of data locality. As a result, a new scheduling policy, Balanced Closer to Finish First (BCFF), is proposed as solutions for some problems of scheduling in MapReduce environment. The scheduling algorithm is implemented in Hadoop 1.0.1 framework and is available as a new Hadoop plug-in Scheduler. The evaluations of the workflow system on the climate data processing and analysis application (several TB dataset) show that it is feasible and significantly improved compared to traditional parallel processing method. The scientific results of the application provide new source of monitoring global climate changes for the near decade 2002-2011.

A Decadal Gridded Hyperspectral Infrared Record for Climate
Sep 1st 2002 – Aug 31st 2012

David Chapman

2:00pm 20 November 2012, ITE 325B

We present a gridded Fundamental Decadal Data Record (FDDR) of Brightness Temperatures (BT) from the NASA EOS Atmospheric Infrared Sounder (AIRS) from ten years of hyperspectral Infrared Radiances onboard the NASA EOS Aqua satellite. We show that these results are consistent with the expected greenhouse forcings, and also discovered a drift of ~0.13K/decade in spectrum relative to 4 MODIS-Aqua for Global All-sky Brightness Temperatures. AIRS, operational on September 1, 2002 is the first successful hyperspectral satellite weather instrument of more than 1 year, as well as the longest running global IR hyperspectral measurement. Although global surface temperature data records are available for over 130 years, it was not until 1978 when the Microwave Sounding Unit (MSU) was the first instrument series to reliably monitor long-term trends of the upper atmosphere. The Atmospheric Infrared Sounder (AIRS) provides the first continuous global hyperspectral IR radiance data record from a single satellite for a decade. Our contribution, was to prepare a gridded data record from the AIRS Outgoing Longwave Spectrum (OLS). We have shown high correlations with the GISS global surface air temperatures as well as with the NOAA ONI index of El Niño phase. In addition, we have performed inter-annual inter-comparisons with the Moderate Resolution Spectroradiometer (MODIS) on the same satellite to examine the relative consistency of their calibrations. The comparisons of the two instruments for the 4µ spectral channels indicate an inter-annual warming of 0.13K per decade of AIRS more than MODIS. This relative decadal drift is small relative to inter-annual variability but on the order of historic surface temperature trends. In the 12µ window channels we see a relative constant difference of 0.01K over a decade. It is convenient to observe the climate variability by using monthly average lat-lon grid projections. The polar orbiting data projection to a lat-lon grid is a lossy process that invariably introduces aliasing artifacts and noise. We observed an exponential decay between the number of days averaged and the expected noise due to gridding. We have extended the Observation Coverage (Obscov) gridding algorithm, developed for the MODIS instrument that incorporates the Point Spread Function (PSF) and we show the Obscov gridding algorithm reduces the aliasing noise from AIRS grids by nearly 40% by comparing the spatial correlation of gridded MODIS IR data. We also show that the use of a circular approximate PSF is a sufficient representation to obtain the noise reduction of Obscov at the climate resolution 0.5×1 degree monthly average grids. We extended these spatial sampling methods to the AIRS Level 3 retrieval records for which quality filtering due to opaque clouds is an additional spatial sampling challenge. We correct for an observed dry bias in the AIRS Level 3 monthly average gridded moisture retrieval records by means of spatial interpolation with the Nearest Neighbor (NN) strategy.
