Patent number: 11929070Abstract: Techniques for performing centralized unsuperivised learning in a multi-domain system are described. A user may request labeled data for an ML task, where the request includes a prompt for obtaining relevant explicit user feedback. The system may use the prompt to collect explicit user feedback for relevant runtime user inputs. After a duration of time (in the user's request for labeled data) has elapsed, the system determines whether collected user feedback indicates processing of the user input was defective and, if so, determines a cause of the defective processing. The system then uses one or more label generators to generate labeled data using the collected user feedback, whether the processing was defective, and the determined defect cause.Type: GrantFiled: August 30, 2021Date of Patent: March 12, 2024Assignee: Amazon Technologies, Inc.Inventors: Ruhi Sarikaya, Zheng Du, Xiaohu Liu, Kai Liu, Sriharsha Venkata Chintalapati, Chenlei Guo, Hung Tuan Pham, Joe Pemberton, Zhenyu Yao, Bigyan Rajbhandari

Patent number: 10705079Abstract: Disclosed is a method for preparing a magnetic microsphere for the separation of biological proteins. A magnetic microsphere matrix is treated by formulating and using an appropriate emulsified liquid, and modification of the surface of the magnetic microsphere matrix is realized by emulsion polymerization, thereby obtaining a magnetic microsphere coated with a polyacrylate polymer layer. Said emulsified liquid comprises the following components therein: acyclic acid monoester compounds, acyclic acid glycol compounds, initiators and optionally anionic surface active agents and water. The magnetic microsphere significantly reduces the non-specific adsorption of other proteins, without affecting the joining ability for a specific protein, when used in the separation of biological proteins. A new selection is provided to realize the separation engineering of high protein specificity adsorption.Type: GrantFiled: May 29, 2014Date of Patent: July 7, 2020Assignee: SHENZHEN NEW INDUSTRIES BIOMEDICAL ENGINEERING CO., LTD.Inventors: Wei Rao, Kai Du, Li Zhao
