Abstract:
A mechanism is provided for enabling prediction of a cost between an origin and a destination even in the case of insufficient past route information. Data D, which includes an origin, a destination, and information on cost between these points, is prepared as well as a subroutine for calculating cost ce along an arbitrary link e on the basis of the set along with a variable denoted by fe. In the first step, the minimum cost route is found from the current {fe} with respect to all pairs of the origin and the destination included in the data D, thereby forming transformed data D′. {fe} is recalculated by using the above subroutine from D′ by computer processing and then compared with {fe} calculated last time. If a change is equal to or greater than a threshold, control returns to finding the minimum cost route. Otherwise, {fe} is fixed.
Abstract:
When an operation mode of a television receiver is a normal mode, insertion of a memory card having trigger information stored therein into a card insertion portion causes a storefront mode setting screen to be displayed on a video display unit. When the operation mode of the television receiver is a storefront mode, detection of supply of power by a power supply detector causes a storefront mode release screen to be displayed on the video display unit. Users performs selection and setting on the storefront mode setting screen and the storefront mode release confirmation screen by operating a remote controller to switch the operation mode of the television receiver.

Abstract:
A differential device has a differential case that houses a gear group, and a ring gear that is disposed fitted to the differential case. The differential case and the ring gear are supported rotatably about a drive shaft. The ring gear is made up of a helical gear. The ring gear abuts the differential case in the axial direction of the drive shaft. The ring gear and the differential case are welded at an abutting portion of the ring gear and the differential case in the axial direction of the drive shaft.
Abstract:
A method and system for analyzing time series data. In an embodiment, a loop is executed and terminated upon a specified maximum number of iterations of the loop being performed or upon a difference between scores in successive iterations of the loop not being greater than a specified tolerance, wherein the score in each iteration is calculated as function of an absolute value of a difference between respective cumulative probability values of first and second cumulative probability distributions which are generated from respectively first and second time series data sets. In an embodiment, time series data is processed in a sequence of time periods, wherein a combined cumulative probability distribution is generated in each time period by combining a cumulative probability distribution of new time series data with previously combined cumulative probability distribution data according to a ratio of the number of new to previous observed values.

Abstract:
Within aspects of the present invention, correlation anomalies are calculated in four stages for a reference data set, and a target data set, respectively, the four stages are: Initially, a similarity matrix K of the variables to be diagnosed is calculated. This similarity matrix is embedded in a low-dimensional vector space in order to calculate and obtain the coordinates {z1, . . . zp} for each variable. Next, an energy value {e1, . . . ep} is calculated per variable from calculated coordinates. Lastly, a comparison is made of the energy values that have been calculated for the target data set with the energy values of that have been calculated for the reference data set in order to determine the degree of correlation anomalies that has occurred between the two data sets.
