Abstract: In some embodiments, a computer-implemented method of training and using a machine learning model is provided. A computing system receives a plurality of sampling data values for a geographical area. The computing system creates an interpolated value map and a variance map for the geographical area using the plurality of sampling data values. The computing system trains a machine learning model using values of the interpolated value map as ground truth values and evaluating performance of the machine learning model using the variance map. The computing system stores the trained machine learning model in a model data store.

Abstract: In some embodiments, techniques for optimizing a design for a physical device to be fabricated by a fabrication system is provided. A computing system receives an initial design. The computing system simulates performance of the initial design to determine a simulated performance metric of the initial design. The computing system determines a Jacobian of the simulated performance metric of the initial design. The computing system backpropagates a gradient of the simulated performance metric of the initial design to generate an updated design. The computing system estimates performance of the updated design using the Jacobian of the simulated performance metric of the initial design to determine an estimated performance metric. The computing system backpropagates a gradient of the estimated performance metric to generate a further updated design.

Abstract: This disclosure describes a system, method, and non-transitory computer readable media for an ultrasound probe configured to capture ultrasound images of an examination region. The system includes a first set of one or more sensors coupled to the ultrasound probe and configured to estimate a first positional information associated with the ultrasound probe. The system includes a second set of one or more sensors coupled to the ultrasound probe and configured to capture electromagnetic force (EMF) measurements in the examination region to estimate a second positional information associated with the ultrasound probe. The second positional information is used to calibrate the first set of one or more sensors. The system includes a controller configured to use at least one of (i) the first positional information, or (ii) the second positional information to generate a reconstruction of the examination region based on ultrasound images captured by the ultrasound probe.

Abstract: The disclosure provides a method for adjusting an optical link alignment of a first communication device with a remote device. The method includes transmitting or receiving an optical signal; receiving one or more measurements of at least one environmental factor at the first communication device or the remote device; and receiving or detecting an apparent amount of alignment of the optical signal. Then, by one or more processors of the first communication device, determining an estimated error attributable to optical cross coupling and an actual amount of alignment of the optical signal based on the apparent amount of alignment and the estimated error. Next, adjusting the first communication device based on the actual amount of alignment to correct for optical cross coupling.

Abstract: In some embodiments, techniques for optimizing a design for a physical device to be fabricated by a fabrication system is provided. A computing system receives an initial design. The computing system uses a fabrication model to determine structural parameters based on the initial design, wherein using the fabrication model includes applying one or more morphological transformations to the initial design that are predicted to be introduced by the fabrication system. The computing system obtains a performance metric by simulating performance of the structural parameters. The computing system determines a loss metric based on the performance metric. The computing system backpropagates a gradient of the loss metric to generate an updated design.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for combining a simulator and neural network for predictions, such as predictions of Harmful Algal Bloom (HAB). One of the methods includes obtaining an estimate of a first number of marine-life cells representative of growth of the marine-life within a first region; providing the estimate to a prediction system that comprises (i) an ocean simulator and (ii) a trained network model, wherein the trained network model is trained to provide an indication of marine-life change using output from the ocean simulator; obtaining output from the prediction system, wherein the output indicates a second number of cells representative of growth of the marine-life within a second region; comparing the output to an output threshold; and in response to the output satisfying the output threshold, performing an action.

Abstract: Aspects of the disclosure provide systems including linear material and tracking tags. A first tracking tag may be at least initially arranged on the liner material. The first tracking tag may also include beacon transmission circuitry including one or more batteries, a top layer, a bottom layer including an adhesive, and an activation mechanism. The activation mechanism may be configured to activate the first tracking tag and cause the beacon transmission circuitry to transmit beacon signals in order to enable tracking of the object. The activation mechanism may further include an initially closed circuit that extends beyond a perimeter of the top layer, and the activation mechanism may be configured to automatically activate the tracking tag when the tracking tag is separated from an adjacent tracking tag on the liner material
