Title: Implicit calibration from screen content for gaze tracking
Inventor: LAGUN DMITRY
IPC: G06F3/01
Filed: 2021-04-21
Abstract: The technology relates to methods and systems for implicit calibration for gaze tracking. This can include receiving, by a neural network module, display content that is associated with presentation on a display screen (1202). The neural network module may also receive uncalibrated gaze information, in which the uncalibrated gaze information includes an uncalibrated gaze trajectory that is associated with a viewer gaze of the display content on the display screen (1204). A selected function is applied by the neural network module to the uncalibrated gaze information and the display content to generate a user-specific gaze function (1206). The user-specific gaze function has one or more personalized parameters. And the neural network module can then apply the user-specific gaze function to the uncalibrated gaze information to generate calibrated gaze information associated with the display content on the display screen (1208). Training and testing information may alternatively be created for implicit gaze calibration (1000).

Abstract: Embodiments disclosed herein generally relate to multi-arm machine learning models for lesion detection. Particularly, aspects of the present disclosure are directed to accessing a three-dimensional magnetic resonance imaging (MRI) images. Each of the three-dimensional MRI images depict a same volume of a brain of a subject. The volume of the brain includes at least part of one or more lesions. Each three-dimensional MRI image of the three‑dimensional MRI images is processed using one or more corresponding encoder arms of a machine-learning model to generate an encoding of the three-dimensional MRI image. The encodings of the three-dimensional MRI images are concatenated to generate a concatenated representation. The concatenated representation is processed using a decoder arm of the machine-learning model to generate a prediction that identifies one or more portions of the volume of the brain predicted to depict at least part of a lesion.

Abstract: Computer system (100), computer-implemented method and computer program product are provided for training a reinforcement learning model (130) to provide operating instructions for thermal control of a blast furnace. A domain adaptation machine learning model (110) generates a first domain invariant dataset (22) from historical operating data (21) obtained as multivariate time series and reflecting thermal states of respective blast furnaces (BF1 to BFn) of multiple domains. A transient model (121) of a generic blast furnace process is used to generate artificial operating data (24a) as multivariate time series reflecting a thermal state of a generic blast furnace (BFg) for a particular thermal control action (26a). A generative deep learning network (122) generates a second domain invariant dataset (23a) by transferring the features learned from the historical operating data 21 to the artificial operating data (24a). The reinforcement learning model (130) determines (1400) a reward (131) for the particular thermal control action (26a) in view of a given objective function by processing the combined first and second domain invariant datasets (22, 23a). Dependent on the reward (131), the second domain invariant data set is regenerated based on modified parameters (123-2), and repeating the determining of the reward to learn optimized operating instructions for optimized thermal control actions to be applied for respective operating states of one or more blast furnaces.

Abstract: Embodiments described herein provide for a voice biometrics system execute machine-learning architectures capable of passive, active, continuous, or static operations, or a combination thereof. Systems passively and/or continuously, in some cases in addition to actively and/or statically, enrolling speakers as the speakers speak into or around an edge device (e.g., car, television, radio, phone). The system identifies users on the fly without requiring a new speaker to mirror prompted utterances for reconfiguring operations. The system manages speaker profiles as speakers provide utterances to the system. Machine-learning architectures implement a passive and continuous voice biometrics system, possibly without knowledge of speaker identities. The system creates identities in an unsupervised manner, sometimes passively enrolling and recognizing known or unknown speakers. The system offers personalization and security across a wide range of applications, including media content for over-the-top services and IoT devices (e.g., personal assistants, vehicles), and call centers.
