  • Torlak, Emina; Jackson, Daniel (2006-09-29)
    The key design challenges in the construction of a SAT-based relational engine are described, and novel techniques are proposed to address them. An efficient engine must have a mechanism for specifying partial solutions, ...
  • Benjamin, Michael R. (2004-09-27)
    The interval programming model (IvP) is a mathematical programmingmodel for representing and solving multi-objective optimizationproblems. The central characteristic of the model is the use ofpiecewise linearly defined ...
  • Kumar, Ravi; Liben-Nowell, David; Novak, Jasmine; Raghavan, Prabhakar; Tomkins, Andrew (2005-06-03)
    We introduce a formal model for geographic social networks, and introduce the notion of rank-based friendship, in which the probability that a person v is a friend of a person u is inversely proportional to the number of ...
  • Saff, David; Boshernitsan, Marat; Ernst, Michael D. (2008-01-14)
    Automated testing during development helps ensure that software works according to the test suite. Traditional test suites verify a few well-picked scenarios or example inputs. However, such example-based testing does not ...
  • Perry, John C. (2007-06-12)
    A longstanding controversy in philosophy is whether decision-making isgoverned by reason or emotion. I study the role of physiologicalresponses in the decision-making process within the realm of financialmarkets, where ...
  • Gilbert, Seth; Malewicz, Grzegorz (2004-10-29)
    Quorum systems are commonly used to maintain the consistency of replicated data in adistributed system. Much research has been devoted to developing quorum systems with good theoreticalproperties, such as fault tolerance ...
  • Hajiaghayi, MohammadTaghi; Sorkin, Gregory B. (2003-11-20)
    We prove that a random 3-SAT instance with clause-to-variable densityless than 3.52 is satisfiable with high probability.The proof comes through an algorithm which selects (and sets) a variabledepending on its degree and ...
  • Lepinski, Matt; Izmalkov, Sergei (2005-02-02)
    We show that any function F can be securely evaluated by a protocolwith ballots and a ballot box. That is, N mutually suspicious players,each player possessing a secret input, can use ballots and a ballotbox to jointly ...
  • Radul, Alexey (2005)
    I devised and implemented a method for constructing regular andsemiregular geometric objects in n-dimensional Euclidean space.Given a finite reflection group (a Coxeter group) G, there is a standard way to give G a group ...
  • Kaynar, Dilsun K.; Lynch, Nancy; Segala, Roberto; Vaandrager, Frits (2003-08-27)
    Revised version -- November 23, 2004.This paper presents the Timed Input/Output Automaton (TIOA) modeling framework, a basic mathematical framework to support description and analysis of timed systems.
  • Kaynor, Dilsun K.; Lynch, Nancy; Segala, Roberto; Vaandrager, Frits (2005-03-02)
    This monograph presents the Timed Input/Output Automaton (TIOA) modeling framework, a basic mathematical framework to support description and analysis of timed systems.
  • Tan, Cheston; Leibo, Joel Z; Poggio, Tomaso (2012)
    In recent years, scientific and technological advances have produced artificial systems that have matched or surpassed human capabilities in narrow domains such as face detection and optical character recognition. However, ...
  • Shrobe, Howard; Knight, Thomas; Hon, Andre de (2007-05-30)
    The last 20 years have led to unprecedented improvements in chipdensity and system performance fueled mainly by Moore's Law. Duringthe same time, system and application software have bloated, leadingto unmanageable ...
  • Torralba, Antonio; Fergus, Rob; Freeman, William T. (2007-04-23)
    The human visual system is remarkably tolerant to degradations in image resolution: in a scene recognition task, human performance is similar whether $32 \times 32$ color images or multi-mega pixel images are used. With ...
  • Benjamin, Michael R.; Leonard, John J.; Schmidt, Henrik; Newman, Paul M. (2009-02-13)
    This paper provides an overview of the MOOS-IvP autonomy software modules. The MOOS-IvP collection of software, i.e., codebase, described here has been developed and is currently maintained by three organizations - Oxford ...
  • Tellex, Stefanie; Thaker, Pratiksha; Deits, Robin; Simeonov, Dimitar; Kollar, Thomas; Roy, Nicholas (2012-01-23)
    Our goal is to build robots that can robustly interact with humans using natural language. This problem is extremely challenging because human language is filled with ambiguity, and furthermore, the robot's model of the ...
  • Brodsky, Micah; Efstathopoulos, Petros; Kaashoek, Frans; Kohler, Eddie; Krohn, Maxwell; Mazieres, David; Morris, Robert; VanDeBogart, Steve; Yip, Alexander (2007-08-06)
    We present a secure service prototype built from untrusted,contributed code.The service manages private data for a variety of different users, anduser programs frequently require access to other users' private data.However, ...
  • Rohanimanesh, Khashayar; Roy, Nicholas; Tedrake, Russ (2007-11-01)
    Choosing features for the critic in actor-critic algorithms with function approximation is known to be a challenge. Too few critic features can lead to degeneracy of the actor gradient, and too many features may lead to ...
  • Rahul, Hariharan; Kasbekar, Mangesh; Sitaraman, Ramesh; Berger, Arthur (2005-11-01)
    Prior analyses of the benefits of routing overlays are based onplatforms consisting of nodes located primarily in North America, onthe academic Internet, and at the edge of the network. This paper isthe first global study ...
  • Geiger, Gadi; Amara, Domenic G (2005-10-18)
    Previous studies have shown that dyslexic individuals who supplement windowed reading practice with intensive small-scale hand-eye coordination tasks exhibit marked improvement in their reading skills. Here we examine ...
