20090044403 | SYSTEM AND METHOD FOR IMPROVING POWER DISTRIBUTION CURRENT MEASUREMENT ON PRINTED CIRCUIT BOARDS - A method and system for improving power distribution and/or current measurement on a printed circuit board is disclosed. According to the invention, a first power plane adapted for current measurement includes a first segment to which a current source is connected and a second segment to which other devices may be connected, forming the current load. A third segment is used to measure the current between the first segment and the second segment through two vias that link two points of the third segment to, preferably, two pads of the external layer. In a preferred embodiment, vias are connected to the first segment so that current flow in the third segment is linear, to improve and simplify current determination. The resistivity between the pair of vias may be computed or estimated using calibrated currents. | 02-19-2009 |

20090018995 | Semi-supervised visual clustering - A clustering system includes a visual mapping sub-system configured to display an N-dimensional to two- or three-dimensional mapping of items to be clustered, where N is greater than three, the mapping having mapping parameters for the N-dimensions. A user interface sub-system is configured to receive user inputted values for the mapping parameters, user inputted values selecting whether selected mapping parameters are fixed or adjustable, and user inputted values associating selected items with selected groups. An adjustment sub-system is configured to adjust the adjustable mapping parameters, without adjusting any fixed mapping parameters, to improve a measure of distinctness of one or more groups of items in the two- or three-dimensional mapping. | 01-15-2009 |
20090271338 | SCALABLE FEATURE SELECTION FOR MULTI-CLASS PROBLEMS - In a feature filtering approach, a set of relevant features and a set of training objects classified respective to a set of classes are provided. A candidate feature and a second feature are selected from the set of relevant features. An approximate Markov blanket criterion is computed that is indicative of whether the candidate feature is redundant in view of the second feature. The approximate Markov blanket criterion includes at least one dependency on less than the entire set of classes. An optimized set of relevant features is defined, consisting of a sub-set of the set of relevant features from which features indicated as redundant by the selecting and computing are removed. | 10-29-2009 |
