  • Borchardt, Gary C. (2014-04-09)
    Moebius is a representation and interface language based on a subset of English. It is designed for use as a means of encoding information and as a means of conveying information between software components and other ...
  • Levine, Steven J. (2012-10-04)
    To achieve robustness in dynamic and uncertain environments, robotic systems must monitor the progress of their plans during execution. This thesis develops a plan executive called Pike that is capable of executing and ...
  • Benjamin, Michael R. (2008-11-11)
    This document describes seven common MOOS-IvP autonomy tools. The uHelmScope application provides a run-time scoping window into the state of an active IvP Helm executing its mission. The pMarineViewer application is a ...
  • Benjamin, Michael R. (2010-08-23)
    This document describes fifteen MOOS-IvP autonomy tools. uHelmScope provides a run-time scoping window into the state of an active IvP Helm executing its mission. pMarineViewer is a geo-based GUI tool for rendering marine ...
  • Benjamin, Michael R. (2011-07-28)
    This document describes 19 MOOS-IvP autonomy tools. uHelmScope provides a run-time scoping window into the state of an active IvP Helm executing its mission. pMarineViewer is a geo-based GUI tool for rendering marine ...
  • Chachulski, Szymon; Jennings, Michael; Katti, Sachin; Katabi, Dina (2006-06-30)
    Opportunistic routing has the potential to substantially increase wireless network throughput. Prior work on opportunistic routing, however, requires tight node coordination. Different nodes in a network must have knowledge ...
  • Park, Jun-geun; Teller, Seth (2014-08-26)
    Indoor localization -- a device's ability to determine its location within an extended indoor environment -- is a fundamental enabling capability for mobile context-aware applications. Many proposed applications assume ...
  • Lynch, Nancy; Mitra, Sayan; Nolte, Tina (2005-04-06)
    We describe how a virtual node abstraction layer can be used to coordinate the motion of real mobile nodes in a region of 2-space. In particular, we consider how nodes in a mobile ad hoc network can arrange themselves along ...
  • Ni, Yuzhao; Frogner, Charles A.; Poggio, Tomaso A. (2013-09-19)
    In this thesis, we designed and implemented a crowdsourcing system to annotatemouse behaviors in videos; this involves the development of a novel clip-based video labeling tools, that is more efficient than traditional ...
  • Drake, Matthew; Hoffmann, Hank; Rabbah, Rodric; Amarasinghe, Saman (2005-10-22)
    Image and video codecs are prevalent in multimedia applications, ranging from embedded systems, to desktop computers, to high-end servers such as HDTV editing consoles. It is not uncommon however that developers create ...
  • Lynch, Nancy; Stoica, Ion (2004-02-19)
    MultiChord is a new variant of the Chord namespace management algorithm [7] that includes lightweight mechanismsfor accommodating a limited rate of change, specifically, process joins and failures. This paper describes ...
  • Mroueh, Youssef; Poggio, Tomaso; Rosasco, Lorenzo; Slotine, Jean-Jacques E. (2011-09-27)
    We study multi-category classification in the framework of computational learning theory. We show how a relaxation approach, which is commonly used in binary classification, can be generalized to the multi-class setting. ...
  • Lau, Eric; Miller, Jason E; Choi, Inseok; Yeung, Donald; Amarasinghe, Saman; Agarwal, Anant (2011-03-25)
    As the push for parallelism continues to increase the number of cores on a chip, and add to the complexity of system design, the task of optimizing performance at the application level becomes nearly impossible for the ...
  • Baldassarre, Luca; Rosasco, Lorenzo; Barla, Annalisa; Verri, Alessandro (2011-01-24)
    In this paper we study a class of regularized kernel methods for vector-valued learning which are based on filtering the spectrum of the kernel matrix. The considered methods include Tikhonov regularization as a special ...
  • Adib, Fadel; Kabelac, Zachary; Katabi, Dina (2014-04-26)
    Recently, we have witnessed the emergence of technologies that can localize a user and track her gestures based purely on radio reflections off the person's body. These technologies work even if the user is behind a wall ...
  • Bileschi, Stanley M (2008-04-09)
    Recently, several powerful image features have been proposed whichcan be described as spatial histograms of oriented energy. Forinstance, the HoG, HMAX C1, SIFT, and Shape Context feature allrepresent an input image using ...
  • Little, Anna V.; Maggioni, Mauro; Rosasco, Lorenzo (2012-09-08)
    Large data sets are often modeled as being noisy samples from probability distributions in R^D, with D large. It has been noticed that oftentimes the support M of these probability distributions seems to be well-approximated ...
  • Finlayson, Mark A.; Halverson, Jeffry R.; Corman, Steven R. (MIT CSAIL, 2014-03-22)
    The N2 Corpus (Narrative Networks Corpus) comprises 100 story texts (42,480 words) relevant to Islamist Extremism, drawn from religious stories, online material, and promotional magazines. The corpus has been annotated for ...
  • Beal, Jacob (2003-08-11)
    Small failures should only disrupt a small part of a network. One wayto do this is by marking the surrounding area as untrustworthy ---circumscribing the failure. This can be done with a distributedalgorithm using ...
  • Katti, Sachin; Rahul, Hariharan; Hu, Wenjun; Katabi, Dina; Crowcroft, Jon (2006-02-16)
    We propose a new architecture for wireless mesh networks. In addition to forwarding packets, routers mix (i.e., code) packets from different sources to increase the information content of each transmission. We show that ...
