    • Exploiting chordal structure in systems of polynomial equations 

      Cifuentes Pardo, Diego Fernando (Massachusetts Institute of Technology, 2014)
      Chordal structure and bounded treewidth allow for efficient computation in linear algebra, graphical models, constraint satisfaction and many other areas. Nevertheless, it has not been studied whether chordality might also ...
    • Exploiting commutativity to reduce the cost of updates to shared data in cache-coherent systems 

      Zhang, Guowei; Horn, Webb H; Sanchez, Daniel (Association for Computing Machinery (ACM), 2015-12)
      We present Coup, a technique to lower the cost of updates to shared data in cache-coherent systems. Coup exploits the insight that many update operations, such as additions and bitwise logical operations, are commutative: ...
    • Exploiting Compositionality to Explore a Large Space of Model Structures 

      Grosse, Roger Baker; Salakhutdinov, Ruslan; Freeman, William T.; Tenenbaum, Joshua B. (AUAI Press, 2012-08)
      The recent proliferation of richly structured probabilistic models raises the question of how to automatically determine an appropriate model for a dataset. We investigate this question for a space of matrix decomposition ...
    • Exploiting continuity-in-time in motion vision 

      Michael, David Joshua (Massachusetts Institute of Technology, 1992)
    • Exploiting cross-channel quantizer error correlation in time-interleaved analog-to-digital converters 

      McMichael, Joseph G.; Maymon, Shay; Oppenheim, Alan V. (Institute of Electrical and Electronics Engineers (IEEE), 2011-11)
      Uniform quantizers are often modeled as additive uncorrelated noise sources. This paper explores the validity of the additive noise model in the environment of time-interleaved A/D converters. Cross-channel quantizer error ...
    • Exploiting E-mail structure to improve summarization 

      Lam, Derek Scott, 1979- (Massachusetts Institute of Technology, 2002)
      For this thesis, I designed and implemented a system to summarize e-mail messages. The system exploits two aspects of e-mail, thread reply chains and commonly-found features, to generate summaries. The system uses existing ...
    • Exploiting feature dynamics for active object recognition 

      Robbel, Philipp; Roy, Deb K. (Institute of Electrical and Electronics Engineers, 2010-12)
      This paper describes a new approach to object recognition for active vision systems that integrates information across multiple observations of an object. The approach exploits the order relationship between successive ...
    • Exploiting fine-grain parallelism in transactional database systems 

      Yan, Cong, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2015)
      Current database engines designed for conventional multicore systems exploit a fraction of the parallelism available in transactional workloads. Specifically, database engines only exploit inter-transaction parallelism: ...
    • Exploiting fitness trade-offs to prevent antifungal drug resistance 

      Vincent, Benjamin Matteson (Massachusetts Institute of Technology, 2015)
      The evolution of drug resistance in pathogenic microorganisms is typically viewed as an inevitable consequence of the selective pressures imposed by antimicrobial agents. However, although certain drugs rapidly lose efficacy ...
    • Exploiting glycan topography for computational design of Env glycoprotein antigenicity 

      Zhao, Peng; Draghi, Monia; Arevalo, Claudia; Karsten, Christina B.; Suscovich, Todd J.; e.a. (Public Library of Science, 2018-04)
      Mounting evidence suggests that glycans, rather than merely serving as a “shield”, contribute critically to antigenicity of the HIV envelope (Env) glycoprotein, representing critical antigenic determinants for many broadly ...
    • Exploiting graphical processing units to enable quantum chemistry calculation of large solvated molecules with conductor-like polarizable continuum models 

      Liu, Fang; Sanchez, David M.; Kulik, Heather Janine; Martínez, Todd J. (Wiley, 2018-10)
      The conductor‐like polarizable continuum model (C‐PCM) with switching/Gaussian smooth discretization is a widely used implicit solvation model in quantum chemistry. We have previously implemented C‐PCM solvation for ...
    • Exploiting hierarchical and temporal information in building predictive models from EHR data 

      Singh, Anima, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2015)
      Clinical predictive modeling has the potential to revolutionize healthcare by allowing caregivers to allocate resources effectively, resulting not only in lower costs but also in better patient outcomes. Electronic health ...
    • Exploiting Hierarchical Context on a Large Database of Object Categories 

      Choi, Myung Jin; Lim, Joseph Jaewhan; Torralba, Antonio; Willsky, Alan S. (Institute of Electrical and Electronics Engineers (IEEE), 2010-08)
      There has been a growing interest in exploiting contextual information in addition to local features to detect and localize multiple object categories in an image. Context models can efficiently rule out some unlikely ...
    • Exploiting inherent robustness and natural dynamics in the control of bipedal walking robots 

      Pratt, Jerry E (Massachusetts Institute of Technology, 2000)
      Walking is an easy task for most humans and animals. Two characteristics which make it easy are the inherent robustness (tolerance to variation) of the walking problem and the natural dynamics of the walking mechanism. In ...
    • Exploiting jet binning to identify the initial state of high-mass resonances 

      Ebert, Markus A.; Liebler, Stefan; Tackmann, Frank J.; Tackmann, Kerstin; Zeune, Lisa; e.a. (American Physical Society, 2016-09)
      If a new high-mass resonance is discovered at the Large Hadron Collider, model-independent techniques to identify the production mechanism will be crucial to understand its nature and effective couplings to Standard Model ...
    • Exploiting Laboratory and Heliophysics Plasma Synergies 

      Dahlburg, Jill; Amatucci, William; Brown, Michael; Chan, Vincent; Chen, James; e.a. (Molecular Diversity Preservation International, 2010-05)
