All hands, no keyboard: New technology can track detailed hand motionResearchers at Microsoft have developed a system that can track -- in real time -- all the sophisticated and nuanced hand motions that people make in their everyday lives. The Handpose system could eventually be used by everyone from law enforcement officials directing robots into dangerous situations to office workers who want to sort through e-mail or read documents with a few flips of the wrist instead of taps on a keyboard.

A Scalable Cloud-Sensor Architecture for the Internet of ThingsRecent advances in IoT and pervasive and ubiquitous computing provide a glimpse into our future and reveal exciting visions of many 'smart' things: smart cities, smart homes, smart cars, all in addition to smart spaces such as malls, workplaces, hotels, schools, and much more. Driven by a technological revolution offering 'low-power many things and wireless almost everything', we could, in only a decade, envision and prototype impressive smart space systems that improve quality of life, enhance awareness...

Human Computer Interaction Mini-Symposium: Four Provocations from the Frontiers of HCIRoel Vertegaal - Queen's UniversityTalk Title: Towards Real Reality (RR) Displays: Some Challenges in Using Flexible Displays for Pixels on Real ObjectsAbstract: In this presentation, I will argue that, just as the CRT was displaced by the LCD, the LCD will, within the next 5 years, be completely displaced by Flexible OLEDs (FOLEDs). There are compelling reasons for this: FOLEDs are lighter, higher contrast, conform better to the user’s body, allow for new form factors, can be manifold, and will be cheaper...

Experiences with Scaling Blockchain-based Data StoresIn the past years cryptocurrency blockchains (like Bitcoin and Namecoin) have seen significant adoption with the promise of using such blockchains as general-purpose databases and/or key-value stores. Cryptocurrency blockchains provide a zero-trust infrastructure, where users can securely store and retrieve information while providing security guarantees that only the owner of a particular private-key can write/modify the data. In theory, many decentralized services/application can be built using...

An Efficient Solver for string and regular expression constraintsAn increasing number of applications in verification and security rely on or could benefit from automatic solvers that can check the satisfiability of constraints over a rich set of data types that includes character strings. Until recently, available string solvers were standalone tools that could reason only about (some fragment) of the theory of strings and regular expressions, sometimes with strong restrictions on the expressiveness of their input language. These solvers were based on reductions to...

The Science of TVThe highest-rated scripted show on TV, The Big Bang Theory often features Sheldon, Howard, Leonard, and Raj wisecracking about scientific principles as if Penny and the rest of us should know exactly what they’re talking about. The Science of TV’s The Big Bang Theory lets all of us in on the punchline by breaking down the show’s scientific conversations. From an explanation of why Sheldon would think 73 is the best number, to an experiment involving the physical stature of Wolowitz women, to an argument...

Measuring Rhetoric: Statistical Language Models in Social ScienceSocial scientists are embracing the idea of using `text as data’ as a way to quantify and evaluate social theories. I’ll discuss a brief history of how this strategy has worked and evolved, and pitch some new approaches for combining social measurement with state-of-the-art natural language processing. We'll focus on the massive multinomial regression models that serve as a basis for text analysis and the distributed computing strategies that allow inference on truly Big Data. I'll then work through a...

Inverting RANSAC: Global Model Detection via Inlier Rate EstimationThis work presents a novel approach for detecting inliers in a given set of correspondences (matches). It does so without explicitly identifying any consensus set, based on a method for inlier rate estimation (IRE). Given such an estimator for the inlier rate, we also present an algorithm that detects a globally optimal transformation. We provide a theoretical analysis of the IRE method using a stochastic generative model on the continuous spaces of matches and transformations. This model allows rigorous...

A Visual Programming Language for building Artificial Biochemistries in HaskellWe describe an expressive visual programming language for defining behaviors manifested by actors reified in a 2D virtual world which can be compiled into programs comprised of combinators which are themselves reified as actors. This permits a large (potentially infinite) set of reified self-replicating programs to be constructed in a system with full referential closure.

Collective Genius: The Art and Practice of Leading InnovationGreat leaders of innovation don't fit the conventional mold of 'good' leadership. They're not visionaries who set direction and inspire others to follow. Instead, they create the context in which others are both willing and able to innovate. As one leader said, 'My job is to set the stage, not to perform on it.' You might think the key to innovation is attracting exceptional creative talent. Or making the right investments. Or breaking down organizational silos. All of these things may help - but there's...

Peer-to-Peer Rental Markets in the Sharing EconomyIn my talk, I will discuss three distinct studies I have worked on, spending a little more time on the first one. The first study presents a new dynamic model of peer-to-peer Internet-enabled rental markets for durable goods in which consumers may also trade their durable assets in (traditional) secondary markets, transaction costs and depreciation rates may vary with usage intensity, and consumers are heterogeneous in their price sensitivity and asset utilization rates. The study characterizes the...

Theory Day Session 5Madhu Sudan - Communication with Imperfectly Shared RandomnessA common feature in natural communication is that it relies on a large shared context between speaker and listener, where the context is shared vaguely rather than precisely. Knowledge of language, technical terms, socio-political events, history etc. all combine to form this shared context; and it should be obvious that no one can expect any part of this context to be shared perfectly by the two parties. This shared context helps in compressing...

Theory Day Session 3Yishay Mansour - Robust inference and local algorithmsRobust inference is an extension of probabilistic inference, where some of the observations are adversarially corrupted. We model it as a zero-sum game between the adversary, who can select a modification rule, and the predictor, who wants to accurately predict the state of nature. There are two variants of the model, one where the adversary needs to pick the modification rule in advance and one where the adversary can select the modification rule...

Theory Day Session 2Ofer Dekel - Bandit Convex Optimization: SqrtT Regret in One DimensionBandit convex optimization is a sequential decision making game with partial information. On each round, an adversary chooses a bounded convex loss function and the decision maker chooses a point in the function's domain. The loss incurred by the decision maker on that round is the value of the loss function at his chosen point. The decision maker observes his loss value (a single number) and uses this information to make better...

Theory Day Session 1Noam Nisan - On the borders of Border's TheoremBorder's theorem characterizes the possible (interim) allocation probabilities in a single item auction. It has received much interest lately in Algorithmic Mechanism Design as it allows optimization in Mechanism Design using polynomial-size linear programs rather than the natural exponential-size ones. Known Generalizations of Border's theorem beyond the simple case of single item auctions are either very limited or are only approximate. This talk will...

Randomized Rounding for the Largest j-Simplex ProblemThe maximum volume j-simplex problem asks to compute the j-dimensional simplex of maximum volume inside the convex hull of a given set of n points in d-dimensional space. We give a deterministic approximation algorithm for this problem which achieves an approximation ratio of ej/2 + o(j) and runs in time polynomial in d and n. The problem is known to be NP-hard to approximate within a factor of cj for some constant c > 1. Our algorithm also approximates the problem of finding the largest determinant...

Scalable Kernel Methods via Doubly Stochastic GradientsThe general perception is that kernel methods are not scalable, and neural nets are the methods of choice for nonlinear learning problems. Or have we simply not tried hard enough for kernel methods? Here we propose an approach that scales up kernel methods using a novel concept called 'doubly stochastic functional gradients'. Our approach relies on the fact that many kernel methods can be expressed as convex optimization problems, and we solve the problems by making two unbiased stochastic approximations...

Long-Range Planning with Time-Inconsistency: A Class of Computational Problems in Behavioral EconomicsThere are many settings where people set long-range goals and make plans to achieve them.
