Publication number: 20240104420Abstract: Certain aspects of the present disclosure provide techniques and apparatus for a training and using machine learning models in multi-device network environments. An example computer-implemented method for network communications performed by a host device includes extracting a feature set from a data set associated with a client device using a client-device-specific feature extractor, wherein the feature set comprises a subset of features in a common feature space, training a task-specific model based on the extracted feature set and one or more other feature sets associated with other client devices, wherein the feature sets associated with the other client devices comprise one or more subsets of features in the common feature space, and deploying, to each respective client device of a plurality of client devices, a respective version of the task-specific model.Type: ApplicationFiled: September 23, 2022Publication date: March 28, 2024Inventors: Kyu Woong HWANG, Seunghan YANG, Hyunsin PARK, Leonid SHEYNBLAT, Vinesh SUKUMAR, Ziad ASGHAR, Justin MCGLOIN, Joel LINSKY, Tong TANG

Publication number: 20240105206Abstract: Certain aspects of the present disclosure provide techniques and apparatus for improved machine learning. Voice data from a first user is received. In response to determining that the voice data includes an utterance of a defined keyword, a user verification score is generated by processing the voice data using a first user verification machine learning (ML) model, and a quality of the voice data is determined. In response to determining that the user verification score and determined quality satisfy one or more defined criteria, a second user verification ML model is updated based on the voice data.Type: ApplicationFiled: September 23, 2022Publication date: March 28, 2024Inventors: Hesu HUANG, Leonid SHEYNBLAT, Vinesh SUKUMAR, Ziad ASGHAR, Joel LINSKY, Justin MCGLOIN, Tong TANG

Patent number: 9588202Abstract: A method and system for providing an article of manufacture with increased longevity of hyperpolarized 1H signals (and other species) for NMR spectroscopy and MRI. The method involves providing a material including a molecular species susceptible of NMR spectroscopy, by providing parahydrogen (and other appropriate species) to disperse within the material/solvent to establish increased longevity of the NMR signals. The material can be in a solution with a surfactant and catalysts added to enhance the persistence of parahydrogen (or other species) in the form of enhanced solubility, microbubbles or micelles and resultant hydrogenation (or other species) of the material.Type: GrantFiled: July 13, 2015Date of Patent: March 7, 2017Assignee: New York UniversityInventors: Joel A. Tang, Francesca Gruppi, Roman Fleysher, Daniel K. Sodickson, James W. Canary, Alexej Jerschow

Patent number: 9195246Abstract: Disclosed are devices, apparatus, circuitry, components, mechanisms, modules, systems, and methods for virtual output voltage sensing for feed-forward control of a voltage regulator. A buffer has an input coupled to sense a monitored signal indicating a duty cycle of switch circuitry coupled to an output filter of the voltage regulator. The buffer is configured to provide at an output, responsive to the monitored signal, a buffer output signal having a high reference voltage for a high side on time and a low reference voltage for a low side on time of the switch circuitry. A filter is coupled to receive and filter the buffer output signal to provide a feed-forward signal indicating the output voltage of the voltage regulator. Control circuitry is configured to control the switching of the switch circuitry responsive to the feed-forward signal.Type: GrantFiled: February 7, 2013Date of Patent: November 24, 2015Assignee: Volterra Semiconductor CorporationInventors: Seth Kahn, Joel Tang, Jingquan Chen
