Computer Science Colloquium, February 20

On Tuesday, February 20, the Computer Science Department will host its secondcolloquium of the Spring 2018 semester.  Dr. Bharathwaj Muthuswamy, visiting professor in the CS Department, give a talk entitled “CUDA and OpenCL: Programming GPUs“.  An abstract of his talk can be found below.

Please join CS faculty and students in Education 113 from 12:30 – 1:30 PM for this talk.


In this talk, Dr. Muthuswamy will go through a high level overview of parallel programming, specifically using (NVIDIA’s) Compute Unified Device Architecture (CUDA) and Khronos Group’s OpenCL (Open Computing Language), for programming Graphics Processing Units (GPUs). We will show examples of parallel programming in practice, starting from the classic “hello, world” to nonlinear dynamics simulations. We will start with CUDA but primarily focus on OpenCL, since the specification is hardware independent.

Dr. Bharathwaj “Bharath” Muthuswamy is currently a visiting professor of computer science at The College of New Jersey (TCNJ). Prior (2015 – 2017) to TCNJ, he was a software engineer for Tarana Wireless, working on implementing real-time network layer code for non-line of sight wireless backhaul devices. Prior (2000 – 2015) to his Tarana Wireless position, Dr. Muthuswamy has worked in both academia (University of California, Berkeley; Milwaukee School of Engineering) and industry (Los Alamos National Laboratory, SUN Microsystems, National Semiconductor and National Instruments). His primary research interests are in nonlinear dynamical (chaotic) systems and embedded (FPGA systems). He is also very passionate about undergraduate, high school and middle school education. He holds a BS (2002), MS (2005) and PhD (2009) all in EECS from the University of California, Berkeley, advised by Dr. Leon O. Chua. His primary PhD contribution was in the design and implementation of a “Muthuswamy-Chua” circuit (system) – the simplest possible chaotic circuit involving only the fundamental circuit elements – an inductor, capacitor and memristor in series.

Computer Science Colloquium, February 2

On Friday, February 2 the Computer Science Department will host its first colloquium of the Spring 2018 semester.  Mr. Marc Wintjen from Bloomberg LP will give a talk entitled “Data Modeling and Visualization“.  An abstract of his talk can be found below.

Please join CS faculty and students in Education 115 from 12:30 – 1:30 PM for this talk.


The true business value from big data comes from understanding how to answer questions before they’re delivered. Once the data is accessible, what techniques are used to visualize data to help tell a story?  This talk will discuss the process used to gather requirements, the methods used to define how to structure data, and the best practices used to create a UI (User Interface) so business users can make data-driven decisions.

Marc Wintjen is a big data architect and data visualization evangelist in the Engineering Business Intelligence team at Bloomberg, LP in Princeton, NJ. He has over 18 years of IT experience in various roles, including project management, Business Intelligence consulting and delivery management in the financial services, pharma and banking industries.

Computer Science Colloquium, April 18

On Tuesday, April 18, the Computer Science Department will host its final colloquium of the Spring 2017 semester.  Mr. Andy Keep, a technical lead from Cisco Systems, Inc., will give a talk entitled “Writing Compilers in Industry“.  An abstract of his talk can be found below.

Please join CS faculty and students in Forcina 408 from 12:30 – 1:30 PM for this talk.

There will be pizza!!!

Compilers are an important tool for working programmers, but few realize the important role compiler researchers and developers continue to play. Having a basic understanding of how a modern compiler works, and what it can (and cannot) do, can help any programmer better understand the performance characteristics of a program. Compilers, both for new languages and existing ones, continue to be developed in industry. Clang has replaced GCC as the C compiler for macOS, and new general purposes languages like Swift and Rust are building on a similar platform. Domain Specific Languages (DSLs) are another important area where compiler technology is brought to bear in industry. In addition to new languages, compilers are also being used to target new devices, including Graphics Processing Units (GPUs), Field Programmable Gate Arrays (FPGAs), and Application Specific Integrated Circuits (ASICs), which is making these traditionally task specific devices into the realm of everyday use.

In this talk I will discuss my experience learning about compilers as a graduate student at Indiana University, and describe how I continue to apply that skill set at Cisco Systems, where I have spent the last three years working on compilers for networking oriented DSLs, most recently P4, a language for specifying the operation of a networking data plane.

Andy Keep is a Technical Lead at Cisco Systems, Inc. where he has spent the better part of the last three years as a compiler engineer, working on compilers for networking related Domain Specific Languages (DSLs). His most recent efforts have focused on a compiler for P4, a DSL for programming network data planes. He is also a maintainer for Chez Scheme, a compiler for the Scheme programming language, originally developed by Andy’s Ph.D. advisor Kent Dybvig, which Cisco released as an open source project in April, 2016. Prior to joining Cisco, Andy spent a year as a post doctoral researcher at the University of Utah, working for Matt Might on static analysis. Andy started working with Matt after finishing his Ph.D. at Indiana University, where he re-wrote the compiler for Chez Scheme, along with his advisor Kent Dybvig, using the nanopass compiler framework.

Computer Science Colloquium, February 3

On Friday, February 3 the Computer Science Department will host its first colloquium of the Spring 2017 semester.  Dr. Steven Skiena, a Distinguished Teaching Professor of Computer Science at Stony Brook University, will give a talk entitled “Applications of Word Embeddings“.  An abstract of his talk can be found below.

Please join CS faculty and students in Forcina 408 from 12:30 – 1:30 PM for this talk.
Light refreshments will be provided.

Distributed word embeddings (word2vec) provides a powerful way to reduce large text corpora to concise features readily applicable to a variety of problems in NLP and data science. I will introduce word embedings, and review several of our recent efforts in my talk, including:

(1) Multilingual NLP — Our Polyglot project employs deep learning and other techniques to build a basic NLP pipeline (including entity recognition, POS tagging, and sentiment analysis) for over 100 different languages. We train our systems over each language’s Wikipedia edition, providing unified data resources in the absence of explicitly annotated data, but substantial challenges in interpretation and evaluation.

(2) Detecting Historical Shifts in Word Meaning — Words like “gay” and “mouse” have substantially shifted their meanings over time in response to societal and technological changes. We use word embeddings trained over texts drawn from different time periods to detect changes in word meanings. This is part of our efforts in historical trends analysis.

(3) Deep Learning for Feature Extraction from Graphs — We present DeepWalk, a novel approach for learning latent representations of vertices in a network. DeepWalk uses local information on truncated random walks to learn embeddings, by treating walks as the equivalent of sentences in a language. It is suitable for a broad class of applications such as network classification and anomaly detection.

This is joint work with Rami al-Rfou, Bryan Perozzi, Vivek Kulkarni, Yanqing Chen, and Charles Ward.

Steven Skiena is Distinguished Teaching Professor of Computer Science at Stony Brook University. His research interests include the design of graph, string, and geometric algorithms, and their applications (particularly to biology). He is the author of five books, including “The Algorithm Design Manual” and “Who’s Bigger: Where Historical Figures Really Rank”. He was co-founder and Chief Scientist at General Sentiment, a media measurement company based on his Lydia text analysis system.

Skiena received his Ph.D. in Computer Science from the University of Illinois in 1988, and the author of over 150 technical papers. He is a former Fulbright scholar, and recipient of the ONR Young Investigator Award and the IEEE Computer Science and Engineer Teaching Award. More info at
