CUNY 2x Tech $1.4M Grant for the department of Computer Systems Technology

City Tech’s CUNY 2x Tech program will support nearly 2,000 students from the Computer Systems Technology department majoring in Computer Information Systems, Computer Systems Technology, and Data Science,” said Pamela Brown, provost and vice president, academic affairs, City Tech. “With a hands-on approach, these majors prepare students for careers in emerging information technologies, with applications in business, science, technology, and other fields. Career exploration and readiness will be integrated throughout the curriculum in all our majors, with the support of newly hired faculty and academic/career advisors with relevant industrial experience. We will also expand upon existing collaborations such as the NYC CEO Jobs Council apprenticeship program and utilize college resources such as tutoring, mentoring, and the Student Success and Professional Development Centers, to ensure academic success. Our Computer Systems Technology students reflect the rich tapestry of New York City, and we are proud of the contributions our graduates make to the diversity of the New York City workforce.

Paper published at International Journal of Mathematical Education in Science and Technology

Paper titled “Introducing computational thinking through hands-on projects using R with applications to calculus, probability and data analysis” is now published. This is work done in collaboration with Math professors (Nadia Benakli, Boyan Kostadinov, Satyanand Singh) at CityTech. 
Abstract: The goal of this paper is to promote computational thinking among mathematics, engineering, science and technology students, through hands-on computer experiments. These activities have the potential to empower students to learn, create and invent with technology, and they engage computational thinking through simulations, visualizations and data analysis. We present nine computer experiments and suggest a few more, with applications to calculus, probability and data analysis, which engage computational thinking through simulations, visualizations and data analysis. We are using the free (open-source) statistical programming language R. Our goal is to give a taste of what R offers rather than to present a comprehensive tutorial on the R language. In our experience, these kinds of interactive computer activities can be easily integrated into a smart classroom. Furthermore, these activities do tend to keep students motivated and actively engaged in the process of learning, problem solving and developing a better intuition for understanding complex mathematical concepts.

Journal Paper published at Microprocessors and Microsystems Journal

Paper titled “Performance modeling of CMOS inverters using support vector machines (SVM) and adaptive sampling” is accepted at the Journal of Microprocessors and Microsystems (Elsevier).

Abstract: Integrated circuit designs are verified through the use of circuit simulators before being reproduced in real silicon. In order for any circuit simulation tool to accurately predict the performance of a CMOS design, it should generate models to predict the transistor’s electrical characteristics. The circuit simulation tools have access to massive amounts of data that are not only dynamic but generated at high speed in real time, hence making fast simulation a bottleneck in integrated circuit design. Using all the available data is prohibitive due to memory and time constraints. Accurate and fast sampling has been shown to enhance processing of large datasets without knowing all of the data. However, it is difficult to know in advance what size of the sample to choose in order to guarantee good performance. Thus, determining the smallest sufficient dataset size that obtains the same accurate model as the entire available dataset remains an important research question. This paper focuses on adaptively determining how many instances to present to the simulation tool for creating accurate models. We use Support Vector Machines (SVMs) with Chernoff inequality to come up with an efficient adaptive sampling technique, for scaling down the data. We then empirically show that the adaptive approach is faster and produces accurate models for circuit simulators as compared to other techniques such as progressive sampling and Artificial Neural Networks.
