Publication number: 20240126808Abstract: In one example method, a first image including M objects is obtained. For N objects in the M objects, when N is greater than or equal to 2, arrangement orders of the N objects is determined, where an arrangement order of any one of the N objects is determined based on at least one of a scene intent weight, a confidence score, or an object relationship score. The scene intent weight is used to indicate a probability that the any object is searched in a scene corresponding to the first image, the confidence score is a similarity between the any object and an image in an image library, and the object relationship score is used to indicate importance of the any object in the first image. Search results of some or all of the N objects are fed back according to the arrangement orders of the N objects.Type: ApplicationFiled: December 20, 2021Publication date: April 18, 2024Inventors: Lei HAO, Yu WANG, Min WANG, Songcen XU, Weicai ZHONG, Zhenhua ZHAO

Patent number: 10565516Abstract: Updating a prediction model, where the prediction model is used for time series data, a computer selects a first prediction time window in an order from a plurality of prediction time windows associated with the prediction model, and predicts predicted values of the time series data at time points within the first prediction time window. The computer calculates a prediction error associated with the first prediction time window based on the one or more predicted values and one or more actual measured values of the time series data at the plurality of time points. The computer determines whether the prediction error is larger than a predefined error threshold associated with the first prediction time window, and in response to determining the prediction error is larger than the predefined error threshold, provides a notification of updating the prediction model.Type: GrantFiled: March 13, 2015Date of Patent: February 18, 2020Assignee: International Business Machines CorporationInventors: Dong Chen, Sier Han, Long Jiao, Jing Zhang, Weicai Zhong
