Publication number: 20240127106Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for online automatic hyperparameter tuning of a machine learning model that provides a user experience to media devices such that the machine learning model maximizes (or minimizes) an objective function. An example embodiment operates by generating an initial set of hyperparameter configurations for a machine learning model based on sampling data received from media devices over a network. The embodiment then determines, using an hyperparameter tuning method, a hyperparameter configuration based on the initial set of hyperparameter configurations that causes a training of the machine learning model using a learning algorithm to maximize an objective function. The embodiment then trains the machine learning model according to the determined hyperparameter configuration using the learning algorithm.Type: ApplicationFiled: October 13, 2022Publication date: April 18, 2024Applicant: Roku, Inc.Inventors: Abhishek BAMBHA, Weicong DING, Zidong WANG, Fei XIAO

Patent number: 11941067Abstract: Disclosed herein are various embodiments, for a content display and clustering system. An example embodiment operates by receiving a request to display the plurality of content items. At each of multiple levels different pairs of content items are identified and a similarity score is computed for each pair. A subset of pairs for which their similarity score exceeds a similarity threshold for the respective level are identified and clustered. This process is repeated for one or more iterations at the same level, and then the process is repeated for each of the multiple levels. A final clustered subset is identified, and output for display, responsive to the request to display the plurality of content items.Type: GrantFiled: September 13, 2022Date of Patent: March 26, 2024Assignee: Roku, Inc.Inventors: Fei Xiao, Ronica Jethwa, Zidong Wang, Jing Lu, Jing Ye, Nam Vo, Jose Sanchez, Abhishek Bambha, Khaldun Aidarabsah

Publication number: 20240064354Abstract: Disclosed are mechanisms for selecting a recommended item for a current item being viewed by a user account based on a view history of the user account with reduced bias. For a current item being viewed by the user account represented by a current node of a co-watch graph, embodiments can select a recommended item represented by an associated node in the co-watch graph likely being viewed by the user account, and determine a probability of the recommended item likely being viewed. The co-watch graph can be generated based on a view history of the user account. An edge between a first node and a second node of the co-watch graph can have a weight representing a number of co-occurrence times when the first item represented by the first node and the second item represented by the second node are viewed in sequence within a predetermined time interval.Type: ApplicationFiled: August 18, 2022Publication date: February 22, 2024Inventors: FEI XIAO, ZIDONG WANG, JOSE SANCHEZ, ABHISHEK BAMBHA, RONICA JETHWA

Publication number: 20230087774Abstract: Example parameter optimization methods and apparatus are described. In one example parameter optimization method, a data processing device obtains a Kronecker factor matrix that is used to indicate a higher-order information matrix of a neural network model, and segments the Kronecker factor matrix to obtain a plurality of square matrices. The obtained plurality of square matrices are submatrices of the Kronecker factor matrix, and main diagonal lines of the plurality of square matrices each are in a one-to-one correspondence with a part of a main diagonal line of the Kronecker factor matrix. Then, the data processing device adjusts a parameter of the neural network model based on the obtained plurality of square matrices.Type: ApplicationFiled: November 29, 2022Publication date: March 23, 2023Inventors: Ningxi NI, Min WANG, Zidong WANG, Fan YU, Lei CHEN

Publication number: 20230092453Abstract: The present disclosure relates to parameter updating methods. In one example method, a parameter in a neural network model is updated for a plurality of times through a plurality of iterations. The plurality of iterations include a first iteration period and a second iteration period. In the first iteration period, an inverse matrix of an additional matrix of the neural network model is updated once based on a quantity of iterations indicated by a first update stride. In the second iteration period, the inverse matrix of the additional matrix of the neural network model is updated once based on a quantity of iterations indicated by a second update stride, where the first iteration of the second iteration period is after the last iteration of the first iteration period in an iteration sequence, and the second update stride is greater than the first update stride.Type: ApplicationFiled: November 23, 2022Publication date: March 23, 2023Inventors: Zidong Wang, Mengyun Chen, Fan Yu, Lei Chen
