Patent number: 11055629Abstract: An online system determines a stability metric that indicates overlap between the set of entities associated with a particular entity when embeddings have been adjusted due to modifications in the input data of an embedding model. The online system generates a stability score for the embedding model by computing a statistic for one or more stability metrics. The online system determines a stability metric for a particular content provider by identifying a first cluster of content providers in a set of first embeddings, and a second cluster of content providers in a set of second embeddings. The second embeddings are generated after modifications have been made to input data. The online system determines the stability metric based on an overlap between the first cluster and the second cluster of content providers. The stability score can be an indicator of model performance that can be used to select embedding models.Type: GrantFiled: October 9, 2017Date of Patent: July 6, 2021Assignee: Facebook, Inc.Inventors: Sina Jafarpour, Qian Yan, Dinkar Jain

Patent number: 10943178Abstract: An online system maintains one or more models that determine likelihoods of a user performing various interactions after being presented with a content item. Additionally, the online system receives information identifying interactions by users with content, and generates embeddings for various users based on the interactions by the users with content. When determining whether to present a content item including an objective identifying an interaction to a user, the online system applies a maintained model to determine a likelihood of the user performing the interaction identified by the objective after being presented with the content item. Additionally, the online system determines a similarity of the embedding of the user to embeddings of users who performed the interaction identified by the objective. Based on a combination of the likelihood determined by the model and the similarity, the online system determines whether to present the content item to the user.Type: GrantFiled: January 31, 2018Date of Patent: March 9, 2021Assignee: Facebook, Inc.Inventors: Tianshi Gao, Yifei Zhang, Sina Jafarpour, Satya Satyavarta, Dinkar Jain, Qian Yan

Patent number: 9417747Abstract: In a touch sensor panel 10 for inputting a position by a touch operation to a predetermined region, a plurality of drive lines DL disposed in one direction and a plurality of sense patterns SL disposed in another direction intersect each other and an electrode size of an electrode of a sense pattern (sense electrode pattern) in one direction disposed between adjacent intersections is switched between at least two electrode sizes of large and small. The configuration enables power consumption to be small while maintaining detection precision of a touched position.Type: GrantFiled: July 9, 2013Date of Patent: August 16, 2016Assignee: SHARP KABUSHIKI KAISHAInventors: Manabu Yumoto, Shunsuke Nagasawa, Yusuke Kanazawa, Qian Yan

Patent number: 9323388Abstract: A touch panel system (1) includes: a touch panel (3) for outputting an output signal in accordance with a presence or absence of an indicator that is in contact with or close to a detection surface P; and an indicator position detection unit (5) for detecting a position of the indicator within the detection surface (P) based on the output signal outputted by the touch panel (3). The indicator position detection unit (5) detects the position of the indicator within the detection surface (P) by use of a detection reference that is set for each predetermined position within the detection surface (P).Type: GrantFiled: July 9, 2013Date of Patent: April 26, 2016Assignee: SHARP KABUSHIKI KAISHAInventors: Manabu Yumoto, Shunsuke Nagasawa, Qian Yan

Publication number: 20140267192Abstract: A stylus pen is obtained that allows accurate detection of a touched position regardless of the tilt of the stylus pen at a time of a touch operation on a capacitive touch panel. A stylus pen 100 comprises a pen body section 103 constituted of a non-conductive member and held by an operator, a pen tip section 102 formed, on one end of the pen body section 103, to taper toward the tip side, and a spherical member 101 constituted of a conductive member and mounted on a tip of the pen tip section, where a contact member is mounted on the pen body section such that a hand of an operator contacts the contact member when the operator holds the pen body section, and the contact member and the spherical member are connected by a conducting wire penetrating through the pen body section and the pen tip section.Type: ApplicationFiled: August 27, 2012Publication date: September 18, 2014Applicant: SHARP KABUSHIKI KAISHAInventors: Yasuhiro Matsuura, Shunsuke Nagasawa, Qian Yan, Tomohiko Nishimura, Shinichi Miyazaki

Publication number: 20090244872Abstract: A portable electronic device (100) is described including a housing (10) and a supporting mechanism (30) supporting the housing. The supporting mechanism includes a shaft (32) secured relative to the housing, a gear (34) rotatably secured with the shaft, a supporting rod (36) secured with the gear, and a rack (38) secured relative to the housing, and further relative to the gear and supporting rod by a meshing of the gear with the rack. The meshing can be changed to drive the supporting rod to rotate relative to the rack and the shaft along with a rotation of the gear about the shaft and along the rack.Type: ApplicationFiled: September 18, 2008Publication date: October 1, 2009Applicants: SHENZHEN FUTAIHONG PRECISION INDUSTRY CO., LTD., FIH (HONG KONG) LIMITEDInventor: FENG-QIAN YAN
