“Data Privacy is Important, But It’s Not Enough“
Our current data ecosystem leaves individuals, groups, and society vulnerable to a wide range of harms, ranging from privacy violations to subversion of autonomy to discrimination to erosion of trust in institutions. In this talk, I’ll discuss the Data Co-ops Project, a multi-institution, multi-disciplinary effort I co-lead with Kobbi Nissim. The Project seeks to organize our understanding of these harms and to coordinate a set of technical and legal approaches to addressing them. In particular, I’ll mention recent joint work with Ayelet Gordon and Alex Wood, wherein we argue that legal and technical tools aimed at controlling data and addressing privacy concerns are inherently insufficient for addressing the full range of these harms.

”Video Data Management: From Data Models to Data Storage and Benchmarking”
The proliferation of inexpensive high-quality cameras coupled with recent advances in machine learning and computer vision have enabled new applications on video data. This in turn has renewed interest in video data management systems. In this talk, we explore several challenges related to video data management. We start by discussing data models. How should we expose video data to make it queryable by applications? We look in particular at the case of 360-degree videos. Second, we explore components of video data storage. How can we store videos in a way that makes them efficiently queryable? Finally, we discuss the problem of benchmarking video data management systems.
2019 Grace Hopper Lecture
Founder of Notable Software, Inc
Despite the provision of a $380M federal grant to enhance technology and improve security in the 2018 midterm elections, machine failures and computer malfunctions again plagued polling places (in GA, PA, NY, IN, TX, and MA), resulting in late openings, long lines, and turned-away voters. Poor ballot layouts resurfaced in Florida, resulting in nearly 25,000 missed votes and the removal of the Broward County Supervisor of Elections, due to “misfeasance, incompetence and neglect of duty.” Many of the unauditable electronic voting machines are now being replaced with paper ballots and scanners, but creative State legislation (including in FL, MI and CA) and new tactics (such as risk-limiting audits) are increasingly being used to thwart and prohibit comprehensive recounts, even when results fall within the range of equipment error. This talk examines some of the shenanigans that we may be looking forward to seeing in 2020, sheds light on the reasons why contrived (and even avoidable) disenfranchisement continues to play a fundamental role in American Democracy, and offers some suggestions for improvement.

“At the Intersection of Data Science and Language”
Abstract: Data science holds the promise to solve many of society’s most pressing challenges, but much of the necessary data is locked within the volumes of unstructured data on the web including language, speech and video. In this talk, I will describe how data science approaches are being used in research projects that draw from language data along a continuum from fact to fiction. I will present research on learning from knowledge of past disasters, as seen through the lens of the media and on the use of data science in understanding subjective, personal narratives of those who have experienced disaster. I will conclude with analysis of both social media and novels.

Rosalind W. Picard, Sc.D., FIEEE
Director of Affective Computing Research
Co-director of Advancing Wellbeing Initiative
Professor of Media Arts and Sciences
MIT Media Lab
Abstract: More than fifteen years ago I set out to create computational systems that could recognize and respond intelligently to emotion. My team and I designed and built the world’s first wearable sensors for classifying human emotion: We developed algorithms using pattern analysis, machine learning, and signal processing for extracting affective information from speech, physiology, facial expressions, and more. Today this work has spawned multiple start-up companies, including Affectiva who has collected more than eleven billion facial emotion points from viewers who opted-in online to turn on their cameras, and Empatica who will soon deliver a wrist-worn sensor that can issue potentially life-saving alerts for people having seizures. In this talk I will tell stories to highlight the most surprising findings during this adventure. These include being wrong about the “true smile of happiness,” discovering that we could enable regular cameras (and smartphones, even while in your pocket) to compute heart rate and respiration accurately, finding electrical signals on the wrist that give insight into deep brain activity, discovering connections to memory consolidation during sleep, and learning of surprising implications of wearable sensing for autism, anxiety, depression, epilepsy, and more.

Abstract: The Internet is a “network of networks”, where global connectivity relies on the competitive cooperation of tens of thousands of separately-administered networks. Over the last several years, the structure of the Internet has changed dramatically with the rapid growth of cloud services and the increasing popularity of video content. However, the Internet’s underlying routing system has been slow to adapt. In this talk, we argue that the emerging technology of Software-Defined Networking (SDN) enables a fresh rethinking of how the Internet delivers traffic. In SDN, a logically-centralized software controller can use a standard interface (e.g., Open Flow) to install packet-processing rules in the underlying network devices.hile initially applied within individual networks, SDN can enable a wide variety of new functionality between administrative domains,including application-specific peering, blocking of unwanted traffic,traffic redirection through so-called “middleboxes”, inbound traffic engineering, and server load balancing. Internet eXchange Points(IXPs)—major juncture points where many networks meet to exchange traffic—are a compelling place to start. We present the design and devaluation of a Software-Defined eXchange (SDX), including new programming abstractions that enable participating networks to create and run applications without conflicting with each other or with today’s global routing system. We also describe a server load-balancing application that we deployed at an operational SDX in New Zealand.

“From Robots to Biomolecules: Computing for the Physical World”
Abstract: This talk will first describe how sampling-based methods revolutionized motion planning in robotics. The presentation will quickly focus on recent algorithms that are particularly suitable for systems with complex dynamics. The talk will then introduce an integrative framework that allows the synthesis of motion plans from high-level specifications. The framework uses temporal logic and formal methods and establishes a tight link between classical motion planning in robotics and task planning in artificial intelligence. Although research initially began in the realm of robotics, the experience gained has led to algorithmic advances for analyzing the motion and function of proteins, the worker molecules of all cells. This talk will conclude by discussing robotics-inspired methods for computing the flexibility of proteins and large macromolecular complexes with the ultimate goals of deciphering molecular function and aiding the discovery of new therapeutics.

“Building Rapport between People and Machines: Why and How”
Abstract: In thinking about the interaction between computers and people we often concentrate on the task or cognitive aspects of the collaboration. However,the social aspects of interaction that characterize human-human collaboration also come into play in human-computer collaboration, and understanding the nature of that social interaction can help us to design computational systems that are most effective in real world contexts. To that end, in this talk I report on a series of studies that look at the building of rapport between humans, and between humans and virtual humans. I look at the effects of this rapport building on tasks as concrete as giving directions and educational tutoring. From the results of these studies I draw conclusions about the need for studies of actual human-human interaction to inform the design of robots and graphical agents and, more generally, the need to have models of the interaction between humans and computers to draw on not just technical but also social and cultural phenomena.

Herchel Smith Professor of Computer Science
School of Engineering and Applied Sciences
Abstract: Digital provenance describes the ancestry or history of a digital object. Computer science research in provenance has addressed issues in provenance capture in operating systems, command shells, languages, work flow systems and applications. However, it’s time to begin thinking seriously about provenance interoperability, what it means, and how we can achieve it. We have undertaken several projects that integrate provenance across multiple platforms. Doing so introduces many challenging research opportunities. In this talk, I’ll present our Provenance-Aware Storage System, focusing on our experiences integrating provenance across different layers of abstraction. I’ll present some of our use cases and discuss important issues for further research.

“Bugs – Find Them Before They Find You”
Abstract: It would obviously be very valuable to know in advance which files in the next release of a large software system are most likely to contain the largest numbers of defects. To accomplish this, we developed a negative binomial regression model and used it to predict the expected number of defects in each file of the next release of a system. The predictions are based on code characteristics and fault and modification history data. We will discuss what we have learned from applying the model to several large industrial systems, each with multiple years of field exposure, and tell you about our success in making accurate predictions and some of the lessons learned and issues that had to be dealt with.
Bio: Elaine Weyuker is an AT&T Fellow doing software engineering research. Prior to moving to AT&T she was a professor of computer science at NYU’s Courant Institute of Mathematical Sciences.

“Intelligent Assistive Technology: The Present and the Future”
Abstract: Recent advances in two areas of computer science-wireless sensor networks and AI inference strategies-have made it possible to envision a wide range of technologies that can improve the lives of people with people with physical, cognitive, and/or psycho-social impairments. This talk will focus on assistive technology for people with cognitive impairment, surveying the state-of-the-art and speculating about future design challenges and opportunities. An important theme will be that the usefulness and effectiveness of these systems depends on their being adaptive to the often highly individualized and changing needs of their users, and that to achieve these properties, designers must integrate a variety of strategies for automated reasoning and learning.

“Interfaces for Controlling Human Characters”
Abstract: Computer animations and virtual environments both require a controllable source of motion for their characters. Most of the currently available technologies require significant training and are not useful tools for casual users. Over the past few years, we have explored several different approaches to this problem. Each solution relies on the information about natural human motion inherent in a motion capture database. For example, the user can sketch an approximate path for an animated character which is then refined by searching a graph constructed from a motion database. We can also find a natural looking motion for a particular behavior based on sparse constraints from the user (foot contact locations and timing, for example) by optimizing in a low-dimensional, behavior-specific space found from motion capture. And finally, we have developed performance animation systems that use video input of the user to build a local Model of the user’s motion and reproduce it on an animated character.

“Probabilistic Models for Complex Domains: Cells, Bodies, and Webpages”
Abstract: Many domains in the real world are richly structured, containing a diverse set of objects, related to each other in a variety of ways. For example, a living cell contains a rich network of interacting genes, that come together to perform key functions. A robot scan of a physical environment contains diverse objects such as people, vehicles, trees, or buildings, each of which might itself be a structured object. And a website contains a set of interlinked webpages, representing diverse kinds of entities. This talk describes a rich language based on probabilistic graphical models, which allows us to model domains such as these. We show how to learn such models from data generated from the domain, and how to use the learned model both to gain a better understanding of the principles underlying these domains, and to allow us to analyze a new data set from these domains in order to recognize the entities in it and the relationships between them. In particular, I will describe applications of this framework to various tasks, including: recognizing regulatory and protein interactions in a cell from diverse types of genomic data; segmenting and recognizing objects in robot laser range scan data; and identifying the set of entities in a structured website and the relationships between them.
