      The pricing problem in a multi-period setting is a challenging problem and has attracted much attention in recent years. In this thesis, we consider a monopoly and an oligopoly pricing problem. In the latter, several sellers ...
    • Multilevel spectral clustering : graph partitions and image segmentation 

      Kong, Tian Fook (Massachusetts Institute of Technology, 2008)
      While the spectral graph partitioning method gives high quality segmentation, segmenting large graphs by the spectral method is computationally expensive. Numerous multilevel graph partitioning algorithms are proposed to ...
    • A multiple secretary problem with switch costs 

      Ding, Jiachuan (Massachusetts Institute of Technology, 2007)
      In this thesis, we utilize probabilistic reasoning and simulation methods to determine the optimal selection rule for the secretary problem with switch costs, in which a known number of applicants appear sequentially in a ...
    • Multiscale Dynamic Time and Space Warping 

      Fitriani (Massachusetts Institute of Technology, 2008)
      Dynamic Time and Space Warping (DTSW) is a technique used in video matching applications to find the optimal alignment between two videos. Because DTSW requires O(N4) time and space complexity, it is only suitable for short ...
    • A multiscale framework for Bayesian inference in elliptic problems 

      Parno, Matthew David (Massachusetts Institute of Technology, 2011)
      The Bayesian approach to inference problems provides a systematic way of updating prior knowledge with data. A likelihood function involving a forward model of the problem is used to incorporate data into a posterior ...
    • Must linear algebra be block cyclic? : and other explorations into the expressivity of data parallel and task parallel languages 

      Sundaresh, Harish Peruvamba (Massachusetts Institute of Technology, 2007)
