Publication number: 20220414474Abstract: A search method based on a neural network model is provided. The neural network model includes a semantic representation model, a recall model, and a ranking model. The present disclosure relates to the field of artificial intelligence, and in particular to the technical field of search. An implementation of the method comprises: inputting a target search and a plurality of objects to be matched to the semantic representation model to obtain a first output of the semantic representation model; inputting the first output of the semantic representation model to the recall model, and obtaining at least one recall object matching the target search from the plurality of objects to be matched by using the recall model; and inputting a second output of the semantic representation model to the ranking model, and obtaining a matching value of each of the at least one recall object by using the ranking model.Type: ApplicationFiled: September 1, 2022Publication date: December 29, 2022Applicant: Beijing Baidu Netcom Science Technology Co., Ltd.Inventors: Hongjian Shi, Xinwei Feng, Feifei Li, Chenyang Guo, Xueqian Wu, Meng Tian, Yu Sun

Patent number: 10405813Abstract: Systems and methods for obtaining a panoramic image are provided. One system includes a gantry, an x-ray source, a receptor, and at least one controller. The x-ray source is mounted on the gantry and is configured to alternatively output x-ray radiation at a first energy level and x-ray radiation at a second energy level. The receptor is mounted on the gantry so that x-ray radiation from the x-ray source impinges on the receptor. The receptor is configured to output a plurality of frames of data including a first frame and a second frame sequential to the first frame. The controller is configured to control the x-ray source so that data in the first frame is generated based on x-ray radiation of the first energy level and data in the second frame is based on x-ray radiation of the second energy level.Type: GrantFiled: February 4, 2015Date of Patent: September 10, 2019Assignees: Dental Imaging Technologies Corporation, PaloDEx Group OYInventors: Petri Jouhikainen, David Albert Sebok, Bradley S. Carlson, Hongjian Shi, Mike Parma, Edward Marandola, Robert Keating, Esa Suuronen, Scott Kravis
