Publication number: 20190279134Abstract: Embodiments of the present invention provide a system, method and computer program product for forecasting a time series based on actuals and a plan. A method comprises generating a first and a second sequence of segments that rise and fall alternately based on a first and a second sequence of data values over time, respectively. The first and second sequence of data values represent actual data for an ongoing project and estimated data for a planned project, respectively. The method further comprises aligning at least one segment of the second sequence of segments with at least one segment of the first sequence of segments, and adjusting the estimated data by replacing at least one segment of the second sequence of segments with a scaled version of at least one corresponding aligned segment of the first sequence of segments. The scaled version maintains an estimated total for the planned project.Type: ApplicationFiled: May 30, 2019Publication date: September 12, 2019Inventors: Jeanette L. Blomberg, Neil H.A. Boyette, Anca A. Chandra, Se Chan Oh, Hovey R. Strong, JR.

Publication number: 20190220780Abstract: Embodiments of the present invention provide a method for detecting a temporal change of name associated with performance data. The method comprises receiving at least one candidate name replacement pair comprising a pair of names. The method further comprises, in a training stage, for each known name replacement pair included in the performance data, determining a window of time covering a most recent appearance of a first name of the known name replacement pair. The window of time is determined based on quantitative features of a time series model comprising performance data for the first name and a second name of the known name replacement pair. The method further comprises, in the training stage, training a machine learning classifier based on quantitative features computed using a portion of the performance data for the first name and the second name, where the portion is within the window of time determined.Type: ApplicationFiled: March 27, 2019Publication date: July 18, 2019Inventors: Jeanette L.

Publication number: 20180301042Abstract: One embodiment provides a method comprising maintaining a weather model based on predicted weather conditions for an air traffic control zone. A hash table comprising multiple hash entries is maintained. Each hash entry comprises a timestamped predicted weather condition for a cell in the zone. A flight plan request for a drone is received. The request comprises a planned flight path for the drone. For at least one cell on the planned flight path, same latitude or same longitude cells, whichever is most closely orthogonal to a direction of the planned flight path, are heuristically probed. Weather conditions for the at least one cell are estimated based on predicted weather conditions for the same latitude or same longitude cells. An executable flight plan is generated if the planned flight path is feasible based on the estimated weather conditions; otherwise, a report including an explanation of infeasibility is generated instead.Type: ApplicationFiled: June 19, 2018Publication date: October 18, 2018Inventors: Jeanette L.

Publication number: 20180053426Abstract: One embodiment provides a method comprising receiving a flight plan request for a drone. The flight plan request comprises a drone identity, departure information, and arrival information.

Publication number: 20180025341Abstract: Embodiments of the invention relate to a system, computer program product, and method for generating a recommendation for using a payment instrument or combination of payment instruments to tender payment. Payment instrument data is stored in a database. Upon receiving a request for a payment recommendation, payment instrument data is retrieved from the database and a payment instrument score is assessed across two or more payment instruments. The assessment comprises the application of a function to a payment instrument, the function taking into account payment instrument variables, category, and location. A recommendation of an apportionment of the payment is generated, including an allocation of an associated cost and the recommended payment is transmitted to a network server.Type: ApplicationFiled: July 25, 2016Publication date: January 25, 2018Applicant: International Business Machines CorporationInventors: Anca A.
