Patent number: 10990899Abstract: In an example, features in a boosting decision tree model are initialized to zero, the boosting decision tree model located in a GLMM and connected to a deep neural network collaborative filtering model via a prediction layer. While the features in the boosting decision tree model remain zero, the deep neural network collaborative filtering model is trained. One or more trees in the boosting decision tree model are boosted using logits produced by the training of the deep neural network collaborative filtering model as a margin. The prediction layer is trained using features from the deep neural network collaborative filtering model and features from the boosting decision tree model. It is then determined whether a set of convergence criteria is met. If not, then the deep neural network collaborative filtering model is retrained using the features and the process is repeated until the set of convergence criteria is met.Type: GrantFiled: August 11, 2017Date of Patent: April 27, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Benjamin Hoan Le, Saurabh Kataria, Nadia Fawaz, Aman Grover, Guoyin Wang

Patent number: 10853925Abstract: Implementations of the disclosure provide for methods, systems, and machine-readable media for image processing. In some embodiments, a method for image processing includes: generating, by a processor, a first histogram and a first parameter set for a first image; constructing, by the processor, a model representative of a second histogram of a second image based on an adjustment parameter set and the first parameter set; generating the second histogram based on the model; and generating a second image based on the first image and the second histogram. In some embodiments, the first histogram is a two-dimensional histogram.Type: GrantFiled: August 2, 2018Date of Patent: December 1, 2020Assignee: CHONGQING UNIVERSITY OF POSTS AND TELECOMMUNICATIONSInventors: Bin Xiao, Guoyin Wang, Weisheng Li
