Speaker: Maria Klawe, President, Harvey Mudd College
Title: Broadening Participation in Computing
Host School: NCSU
Location: Hunt Library Auditorium
Host: Blair Sullivan (blair_sullivan at ncsu.edu)
Computing is one of the least diverse disciplines in science and engineering in terms of participation by women, African-Americans and Hispanics, and the only discipline where participation by women has significantly decreased over the last three decades. While our discipline does well in encouraging members of underrepresented groups to go on to graduate programs, we have been less successful in attracting members of these groups into undergraduate programs. This talk discusses successful strategies for significantly increasing the number of women and students of color majoring in computer science.

Speaker: Moshe Vardi, Karen Ostrum George Distinguished Service Professor in Computational Engineering and Director of the Ken Kennedy Institute for Information Technology, Rice University
Title: Humans, Machines, and Work: The Future is Now
Host School: Duke
Location: LSRC D106
Host: Sudeepa Roy (sudeepa at cs.duke.edu)
Automation, driven by technological progress, has been increasing inexorably for the past several decades. Two schools of economic thinking have for many years been engaged in a debate about the potential effects of automation on jobs: will new technology spawn mass unemployment, as the robots take jobs away from humans? Or will the jobs robots take over create demand for new human jobs?
I will present data that demonstrate that the concerns about automation are valid. In fact, technology has been hurting working Americans for the past 40 years. The discussion about humans, machines and work tends to be a discussion about some undetermined point in the far future. But it is time to face reality. The future is now.

29 January 2018
Speaker: Avrim Blum, Professor of Computer Science and Chief Academic Officer, Toyota Technical Institute at Chicago
Title: Learning about Agents and Mechanisms from Opaque Transactions
Host School: Duke
Location: LSRC D106
Host: Kamesh Munagala (kamesh at cs.duke.edu)
In this talk I will discuss the problem of trying to learn the requirements and preferences of economic agents by observing the outcomes of an allocation mechanism whose rules you also don’t initially know. As an example, consider observing web pages where the agents are advertisers and the winners are those whose ads show up on the given page. We know these ads are placed based on bids and other constraints given to some auction mechanism, but we do not get to see these bids and constraints. What we would like to do is from repeated observations of this type to learn what the requirements and preferences of the agents are. Or consider observing the input-output behavior of some scheduling service, where the input consists of a set of agents requesting service, and the output tells us which actually received service and which did not. In this case, we assume the agents who did not receive service were not served due to overlap of their resource needs with higher-priority requests. From such input-output behavior, we would like to learn the underlying structure. Our goal will be from observing a series of such interactions to try to learn both the needs and preferences of the agents and perhaps also the rules of the allocation mechanism.
This talk is based on work joint with Yishay Mansour and Jamie Morgenstern, as well as work joint with Michael Liang.

26 March 2018
Speaker: Richard Szeliski, Research Scientist and Director of the Computational Photography Group, Facebook Research
Title: Visual Reconstruction and Image-Based Rendering
Host School: Duke
Location: LSRC D106
Host: Xiaobai Sun (xiaobai at cs.duke.edu)
The reconstruction of 3D scenes and their appearance from imagery is one of the longest-standing problems in computer vision. Originally developed to support robotics and artificial intelligence applications, it has found some of its most widespread use in support of interactive 3D scene visualization.
One of the keys to this success has been the melding of 3D geometric and photometric reconstruction with a heavy re-use of the original imagery, which produces more realistic rendering than a pure 3D model-driven approach. In this talk, I give a retrospective of two decades of research in this area, touching on topics such as sparse and dense 3D reconstruction, the fundamental concepts in image-based rendering and computational photography, applications to virtual reality, as well as ongoing research in the areas of layered decompositions and 3D-enabled video stabilization.
Richard Szeliski is a Research Scientist in the Computational Photography group at Facebook, which he founded in 2015. He is also an Affiliate Professor at the University of Washington, and is member of the NAE and a Fellow of the ACM and IEEE. Dr. Szeliski has done pioneering research in the fields of Bayesian methods for computer vision, image-based modeling, image-based rendering, and computational photography, which lie at the intersection of computer vision and computer graphics. His research on Photo Tourism, Photosynth, and Hyperlapse are exciting examples of the promise of large-scale image and video-based rendering.
Dr. Szeliski received his Ph.D. degree in Computer Science from Carnegie Mellon University, Pittsburgh, in 1988 and joined Facebook as founding Director of the Computational Photography group in 2015.

Speaker: Polina Golland, Director of the Computer Science and Artificial Intelligence Laboratory (CSAIL) and Professor of Electrical Engineering and Computer Science, Massachusetts Institute of Technology
Title: Image Imputation
Host School: UNC
Host: Marc Niethammer (mn at cs.unc.edu)
We present an algorithm for creating high resolution anatomically plausible images that are consistent with acquired clinical brain MRI scans with large inter-slice spacing. Although large databases of clinical images contain a wealth of information, medical acquisition constraints result in sparse scans that miss much of the anatomy. These characteristics often render computational analysis impractical as standard processing algorithms tend to fail when applied to such images. Our goal is to enable application of existing algorithms that were originally developed for high resolution research scans to severely undersampled images. We introduce a generative model that captures fine-scale anatomical similarity across subjects in clinical image collections and use it to fill in the missing data in scans with large slice spacing. Our experimental results demonstrate the promise of the resulting algorithm in a context of large studies of neurodegeneration and acute stroke.
Polina Golland is a professor of EECS at MIT CSAIL. She received her Ph.D. from MIT in and her Bachelor and Masters degree from Technion, Israel.

16 April 2018
Speaker: Christopher Manning, Thomas M. Siebel Professor in Machine Learning and Professor of Linguistics and of Computer Science, Stanford University
Title: Building Neural Network Models That Can Reason
Host School: UNC
Host: Mohit Bansal (mbansal at cs.unc.edu)
Deep learning has had enormous success on perceptual tasks but still struggles in providing a model for inference. To address this gap, we have been developing Memory-Attention-Composition networks (MACnets). The MACnet design provides a strong prior for explicitly iterative reasoning, enabling it to support explainable, structured learning, as well as good generalization from a modest amount of data. The model builds on the great success of existing recurrent cells such as LSTMs: A MacNet is a sequence of a single recurrent Memory, Attention, and Composition (MAC) cell. Its careful design imposes structural constraints on the operation of each cell and the interactions between them, incorporating explicit control and soft attention mechanisms into their interfaces. We demonstrate the model’s strength and robustness on the challenging CLEVR dataset for visual reasoning (Johnson et al. 2016), achieving a new state-of-the-art 98.9% accuracy, halving the error rate of the previous best model. More importantly, we show that the new model is more computationally efficient and data-efficient, requiring an order of magnitude less time and/or data to achieve good results. Joint work with Drew Hudson.

Speaker: Jeannette Wing, Avanessians Director of the Data Science Institute and Professor of Computer Science, Columbia University
Title: Data for Good: Data Science at Columbia University
Host School: UNC
Host: Ketan Mayer-Patel (kmp at cs.unc.edu)
Every field has data. We use data to discover new knowledge, to interpret the world, to make decisions, and even to predict the future. The recent convergence of big data, cloud computing, and novel machine learning algorithms and statistical methods is causing an explosive interest in data science and its applicability to all fields. This convergence has already enabled the automation of some tasks that better human performance. The novel capabilities we derive from data science will drive our cars, treat disease, and keep us safe. At the same time, such capabilities risk leading to biased, inappropriate, or unintended action. The design of data science solutions requires both excellence in the fundamentals of the field and expertise to develop applications which meet human challenges without creating even greater risk.
The Data Science Institute at Columbia University promotes “Data for Good”: using data to address societal challenges and bringing humanistic perspectives as—not after—new science and technology is invented. Started in 2012, the Institute is now a university-level institute representing over 300 affiliated faculty from 12 different schools across campus. Data science literally touches every corner of the university.
In this talk, I will present the mission of the Institute, highlights of our educational and research activities, and plans for future initiatives.
