20130066933 | METHOD AND APPARATUS FOR DERIVING COMPOSITE TIE METRIC FOR EDGE BETWEEN NODES OF A TELECOMMUNICATION CALL GRAPH - A method for deriving a composite tie metric for an edge between nodes of a telecommunication call graph includes receiving descriptive data with original values for descriptive attributes associated with a telecommunication call graph formed by edges between nodes. Each edge relates to two nodes. Each original value relates to an edge and a descriptive attribute forming an edge-attribute pair for the corresponding original value. The descriptive data is stored in a local storage device. Scaling factors for each descriptive attribute are determined taking into account a distribution of the original values for the corresponding descriptive attribute and a common base for the descriptive attributes. Weighting factors are determined for each descriptive attribute. The composite tie metric is computed for an edge based on the original value, scaling factor, and weighting factor for the descriptive attributes. | 03-14-2013 |

20110302231 | METHOD AND APPARATUS FOR PERFORMING NUMERICAL CALCULATIONS - There is provided a method of processing an iterative computation on a computing device comprising at least one processor. Embodiments of the method comprises performing, on a processor, an iterative calculation on data in a fixed point numerical format having a scaling factor, wherein the scaling factor is selectively variable for different steps of said calculation in order to prevent overflow and to minimise underflow. By providing such a method, the reliability, precision and flexibility of floating point operations can be achieved whilst using fixed point processing logic. The errors which fixed-point units are usually prone to generate if the range limits are exceeded can be mitigated, whilst still providing the advantage of a significantly reduced logic area to perform the calculations in fixed point. | 12-08-2011 |

20110173243 | SCALED EXPONENTIAL SMOOTHING - A method and system for scaled exponential smoothing are provided. Multiple exponentially smoothed values are maintained for items and events occur on one or more of the items. The method maintains a gradually inflated representation of the smoothed values of items, such that the representation at a given time for an item where no event has occurred is not altered. Using a scaling technique enables the smoothed values for the objects on which an event has not occurred to remain the same. This reduces the number of calculations required significantly, enabling the use of the smoothing technique in a wide range of applications. | 07-14-2011 |

20090265404 | FAST SINGULAR VALUE DECOMPOSITION FOR EXPEDITING COMPUTER ANALYSIS SYSTEM AND APPLICATION THEREOF - The present invention uses a computer analysis system of a fast singular value decomposition to overcome the bottleneck of a traditional singular value decomposition that takes much computing time for decomposing a huge number of objects, and the invention can also process a matrix in any form without being limited to symmetric matrixes only. The decomposition and subgroup concept of the fast singular value decomposition works together with the decomposition of a variance matrix and the adjustment of an average vector of a column vector are used for optimizing the singular value decomposition to improve the overall computing speed of the computer analysis system. | 10-22-2009 |

20140074900 | ARCHITECTURE GUIDED OPTIMAL SYSTEM PRECISION DEFINITION ALGORITHM FOR CUSTOM INTEGRATED CIRCUIT - Systems and methods are disclosed to automatically determine an optimal number format representation for a model or code to be implemented in a custom integrated circuit (IC) by determining a ratio of dynamic range to static range in the model or code, and selecting a floating point or a fixed point number representation based on the ratio; determining the optimal number representation format based on a cost function that includes hardware area and power cost associated with a predetermined bit precision arithmetic; automatically generating a processor architecture customized to the optimal number representation format; and synthesizing the generated processor architecture into a computer readable description of the custom integrated circuit for semiconductor fabrication. | 03-13-2014 |

20100250636 | APPARATUS AND METHODS FOR DYNAMIC DATA-BASED SCALING OF DATA - Disclosed are apparatus and methods for dynamic data-based scaling of data. The disclosed methods and apparatus involve storing one or more input data samples, which are to be scaled and input to a processing function such as a Fast Fourier Transform. A scaling value operable for scaling the one or more data samples is determined based on the one or more input data samples, and then the stored data samples are scaled based on the computed scaling value when read out of storage prior to the processing function. The scaling of data based on the input data allows the data to be scaled dynamically, not statically, and ensures that the data fits within a desired bit width constraint of the processing function thereby economizing processing resources. | 09-30-2010 |

20120246208 | FIR Filter with Reduced Element Count - A finite impulse response (FIR) filter having a differential output and capable of having negative coefficients, and a method of designing the filter, is disclosed. In contrast to the prior art, in which two output signals requires the use of two identical sets of impedance devices corresponding to the Fourier coefficients that create the desired response of the filter, the described method and system uses only a single set of impedance devices, and thus approximately one-half of the number of impedance devices used in the prior art. This is accomplished by appropriately selecting which resistors contribute to which output, so that a differential output may be obtained that is substantially the same as if impedance devices corresponding to all of the coefficients were used for each signal. | 09-27-2012 |
