Patent number: 11861490Abstract: A machine learning environment utilizing training data generated by customer environments. A reinforced learning machine learning environment receives and processes training data generated by independently hosted, or decoupled, customer environments. The reinforced learning machine learning environment corresponds to machine learning clusters that receive and process training data sets provided by the decoupled customer environments. The customer environments include an agent process that collects training data and forwards the training data to the machine learning clusters without exposing the customer environment. The machine learning clusters can be configured in a manner to automatically process the training data without requiring additional user inputs or controls to configured the application of the reinforced learning machine learning processes.Type: GrantFiled: November 21, 2018Date of Patent: January 2, 2024Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Saurabh Gupta, Bharathan Balaji, Leo Parker Dirac, Sahika Genc, Vineet Khare, Ragav Venkatesan, Gurumurthy Swaminathan

Patent number: 10467729Abstract: A method and system for a deep learning-based approach to image processing to increase a level of optical zooming and increasing the resolution associated with a captured image. The system includes an image capture device to generate a display of a field of view (e.g., of a scene within a viewable range of a lens of the image capture device). An indication of a desired zoom level (e.g., 1.1× to 5×) is received, and, based on this selection, a portion of the field of view is cropped. In one embodiment, the cropped portion displayed by the image capture device for a user's inspection, prior to the capturing of a low resolution image. The low resolution image is provided to an artificial neural network trained to apply a resolution up-scaling model to transform the low resolution image to a high resolution image of the cropped portion.Type: GrantFiled: October 12, 2017Date of Patent: November 5, 2019Assignee: Amazon Technologies, Inc.Inventors: Pramuditha Hemanga Perera, Gurumurthy Swaminathan, Vineet Khare

Patent number: 10360482Abstract: Features related to systems and methods for generating a machine learning model that is a composite of at least two other models (e.g., crowd-sourced models contributed by users) are described. Each of the contributed models provide output values that may not be to scale. To account for these differences, a normalization factor for a first machine learning model is generated to adjust values produced by the first machine learning model to correspond with results from the second machine learning model. The crowd-sourced models along with the normalization factor are included in the new image model generated in the claims.Type: GrantFiled: December 4, 2017Date of Patent: July 23, 2019Assignee: Amazon Technologies, Inc.Inventors: Vineet Khare, Gurumurthy Swaminathan, Xiong Zhou
