  • Publication number: 20090198640
    Abstract: Systems and methods for extracting or analyzing time-series behavior are described. Some embodiments of computer-implemented methods include generating fuzzy rules from time series data. Certain embodiments also include resolving conflicts between fuzzy rules according to how the data is clustered. Some embodiments further include extracting a model of the time-series behavior via defuzzification and making that model accessible. Advantageously, to resolve conflicts between fuzzy rules, some embodiments define Gaussian functions for each conflicting data point, sum the Gaussian functions according to how the conflicting data points are clustered, and resolve the conflict based on the results of summing the Gaussian functions. Some embodiments use both crisp and non-trivially fuzzy regions and/or both crisp and non-trivially fuzzy membership functions.

  • Patent number: 7509431
    Abstract: A method is disclosed for performing message and transformation adapter functions in a network element on behalf of an application. According to one aspect, the network element determines an application layer message that is collectively contained in payload portions of data packets. The application layer message conforms to an application layer protocol, such as Hypertext Transfer Protocol (HTTP). The network element determines the application layer protocol to which the application layer message conforms. Based on the application layer protocol, an adapter is selected from among a plurality of adapters that are accessible to the network element. The application layer message is provided to the selected adapter, which converts the application layer message into a “canonical” message that is not specific to any particular application layer protocol.

  • Patent number: 7295614
    Abstract: The present invention relates to systems and methods for compressing, decompressing, and transmitting video data. The systems and methods include pixel by pixel motion estimation and compensation and efficient quantization of residual errors. The present invention applies block estimation of the residual error produced by motion compensation. The block estimation is applied by a local decoder to generate synthesized blocks of video data. The block estimation approximated uses a set of predetermined motion estimation errors that are stored as error vectors in a codebook. The codebook is included in an encoder of the present invention and converts an error vector for each block to an error vector index. The error vector index, which introduces minimal transmission burden, is then sent from the encoder to a target decoder. A receiving decoder also includes a copy of the codebook and converts the error vector index to its associated error vector for reconstruction of video data.

  • Publication number: 20070203694
    Abstract: 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.

  • Publication number: 20060200346
    Abstract: Auditory processing is used in conjunction with cognitive mapping to produce an objective measurement of speech quality that approximates a subjective measurement such as MOS. In order to generate a data model for measuring speech quality from a clean speech signal and a degraded speech signal, the clean speech signal is subjected to auditory processing to produce a subband decomposition of the clean speech signal; the degraded speech signal is subjected to auditory processing to produce a subband decomposition of the degraded speech signal; and cognitive mapping is performed based on the clean speech signal, the subband decomposition of the clean speech signal, and the subband decomposition of the degraded speech signal. Various statistical analysis techniques, such as MARS and CART, may be employed, either alone or in combination, to perform data mining for cognitive mapping.
