International Classification:

G06F 17/30

US Classification:

707801

Abstract:

Records representing items in a dimensionally-modeled fact collection are assigned to bins. A count-based portion of a user interface receives user bin assignment specification of the records based on user-specified counts of records. Actual counts for bin assignment are determined by constraining records having a same data value at a specified particular dimension to be within the same bin. A user-observable indication of the determined actual counts is provided. The user interface may include a value-based portion. The value-based portion of the user interface may be operated to receive user indication of bin assignment specification of records based on user-specified at least one value at the particular dimension. Determining actual counts includes reconciling the user indication of bin assignment specification in the count-based portion with the user indication of bin assignment specification in the value-based portion.

International Classification:

G06F 17/30

US Classification:

711172, 707720

Abstract:

A portion of data records of a full input data set are imported into memory of a computer system for processing by an executing application. The full input data set includes data records of a dimensionally-modeled fact collection. An amount of the data of the full input set to import is determined based on an amount of available memory of the computer system. The sampling characteristics for sampling the full input data set are determined based on the amount of the data that can be imported and on characteristics of the full input data set and application involved. The full input data set is then sampled and a portion of the records are imported into the memory of the computer system for processing. The sampling characteristics are determined such that analysis as a result of processing by the executing application of the sampled portion of the records imported is representative of the analysis that could otherwise be carried out on the full input data set, with a calculable statistical relevance.

International Classification:

G06F 15/18
G06E 1/00
G06E 3/00
G06G 7/00

US Classification:

706 17

Abstract:

An unsupervised classification approach is improved by imposing some order into the treatment of the records and their attributes, which otherwise would be treated as random variables. A method is provided to identify particular attributes that are most associated with the “good” records within each of the plurality of groups of records within a data set. Based on a supervised scoring method, the records of the data set are processed to indicate their measure of “goodness”. There are various ways by which the records can be processed to indicate a bias during unsupervised clustering processing.

International Classification:

G06F 17/30

US Classification:

707737

Abstract:

A system and method to facilitate interactive selection of groupings of clusters and presentation of related datasets are described. An interactive data interface is presented to a user in a display window, the interactive data interface configured to display multiple alternate groupings of clusters associated with at least one dataset of records targeted by the user. Selection of a grouping of clusters from the plurality of selectable groupings is further facilitated based on one or more predetermined parameters associated with each grouping of clusters and the individual clusters within a respective grouping, such as, for example, a target ratio value and a target count value corresponding to each cluster of records.

Abstract:

Methods having corresponding apparatus and computer-readable media comprise: receiving television signals and a message at an apparatus, wherein the television signals include an NTSC television signal and an ATSC television signal, wherein the message represents first and second arrival times representing absolute times of arrival at the apparatus of a first wavefront of the NTSC and ATSC television signals, respectively; measuring third and fourth arrival times, based on a local clock, after receiving the message, wherein the third and fourth arrival times represent times of arrival at the apparatus of a second wavefront of the NTSC and ATSC television signals, respectively; and providing a clock correction signal for the local clock based on the first arrival time, the second arrival time, the third arrival time, and the fourth arrival time.
