The system and method permit the tracking of the activities within the system, including the distribution and use of the information by users, when they accessed the information and how frequently it was accessed, etc. The system and method is designed for the managed widespread distribution of information to a variety of types of users and yet can operate with relatively inexpensive computing equipment at user locations. | 09-18-2014 |

20090021403 | METHOD AND SYSTEM FOR REDUCING CONTEXTS FOR CONTEXT BASED COMPRESSION SYSTEMS - For context based compression techniques, for example Context Based YK compression, a method and system for grouping contexts from a given context model together to create a new context model that has fewer contexts, but retains acceptable compression gains compared to the context model with more contexts is provided. According to an exemplary embodiment a set of files that are correlated to the file to be compressed (hereafter called training files) are read to determine, for an initial context model, the empirical statistics of contexts and symbols. In some embodiments, this includes determining the estimated joint and conditional probabilities of the various contexts and symbols (or blocks of symbols). The initial context model is then reduced to a desired number of contexts, for example, by applying a grouping function g to the original set of contexts to obtain a new and smaller set of contexts. In some embodiments the step of applying a grouping function comprises iteratively grouping a pair of contexts together to form a grouped context, wherein each grouped context represents a local minimum based on the empirical statistics. | 01-22-2009 |

Otherwise, if the unit of side information is not resident on the mobile device, the method includes requesting the unit of side information from one of the server and another device. | 08-20-2009 |

20110288865 | Single-Sided Speech Quality Measurement - A non-intrusive speech quality estimation technique is based on statistical or probability models such as Gaussian Mixture Models (“GMMs”). Perceptual features are extracted from the received speech signal and assessed by an artificial reference model formed using statistical models. The models characterize the statistical behavior of speech features. Consistency measures between the input speech features and the models are calculated to form indicators of speech quality. The consistency values are mapped to a speech quality score using a mapping optimized using machine learning algorithms, such as Multivariate Adaptive Regression Splines (“MARS”). The technique provides competitive or better quality estimates relative to known techniques while having lower computational complexity. | 11-24-2011 |
