    Abstract:

    With the end of Dennard scaling, architects have increasingly turned to special-purpose hardware accelerators to improve the performance and energy efficiency for some applications. Unfortunately, accelerators don't always live up to their expectations and may under-perform in some situations. Understanding the factors which effect the... Read More

    In this talk we will discuss DataHub, a platform to enable data collaboration for teams to collectively curate and analyze large datasets. Inspired by software version control systems like git, we propose a dataset version control system, giving users the ability to create, branch, merge, difference and search large, divergent collections of datasets, and a platform that gives users the ability to perform collaborative data analysis building on this version control system. We will detail a relational storage manager, Decibel, that explores alternative storage schemes to efficiently store... Read More

    Computer Sciences 1240
    Steve Marschner
    Cornell University

    Abstract:

    In computer graphics, detail is an important part of the big picture. The eye uses fine detail in images to learn about materials, and leaving this structure out lends surfaces a too-smooth appearance that makes them look synthetic. This talk looks at at two projects that focus on getting the details right and find that surprisingly small features matter. The first starts with the straightforward problem of rendering rough surfaces, which are covered with details much smaller than pixels. Techniques for filtering out the too-small details are good at getting the right... Read More

    4310 CS
    Dimitris Paparas
    University of Wisconsin - Madison

    We study the problem of efficiently finding a Market Equilibrium in an Arrow-Debreu market. We start by proving PPAD-hardness for the long-standing open problem regarding the complexity of computing an approximate Arrow-Debreu market equilibrium in markets with Constant Elasticity of Substitution (CES) utilities. Building on this result, we introduce the notion of non-monotone utilities, which covers a wide variety of utility functions in economic theory, and show that it is PPAD-hard to compute an approximate Arrow-Debreu market equilibrium in markets with linear and non-monotone...
