  • Age classification from facial images for detecting retinoblastoma. 

    Chiam, Tak Chien. (, 2012-11-29)
    Facial age estimation from images is a difficult problem, both because it is naturally difficult to tell the exact age of a person visually, and because of the variations in images, such as illumination, pose, and expression. ...
  • Faster k-means clustering. 

    Drake, Jonathan, 1989- (, 2013-09-24)
    The popular k-means algorithm is used to discover clusters in vector data automatically. We present three accelerated algorithms that compute exactly the same clusters much faster than the standard method. First, we redesign ...
  • Information storage capacity of genetic algorithm fitness maps. 

    Montañez, George D. (, 2011-09-14)
    To accurately measure the amount of information a genetic algorithm can generate, we must first measure the amount of information one can store, using a fitness map. The amount of information generated, minus the storage ...
  • PG-means: learning the number of clusters in data. 

    Feng, Yu. (2007-03-19)
    We present a novel algorithm called PG-means in this thesis. This algorithm is able to determine the number of clusters in a classical Gaussian mixture model automatically. PG-means uses efficient statistical hypothesis ...
  • Studies of active information in search. 

    Ewert, Winston. (2010)
    A search process is an attempt to locate a solution to a problem, such as an optimization problem, where the space is usually too large to exhaustively sample. In order to investigate this idea this work looks a three ...
