  • Patent number: 10664756
    Abstract: In one embodiment, a computer-implemented method includes receiving training data including a plurality of records, each record having a plurality of attributes. The training data is horizontally parallelized across two or more processing elements. This horizontal parallelizing includes dividing the training data into two or more subsets of records; assigning each subset of records to a corresponding processing element of the two or more processing elements; transmitting each subset of records to its assigned processing element; and sorting, at the two or more processing elements, the two or more subsets of records to two or more candidate leaves of a decision tree. The output from horizontally parallelizing is converted into input for vertically parallelizing the training data. The training data is vertically parallelized across the two or more processing elements. The decision tree is grown based at least in part on the horizontally parallelizing, the converting, and the vertically parallelizing.

  • Publication number: 20200132716
    Abstract: Microelectromechanical system (MEMS) accelerometers are described. The MEMS accelerometers may include multiple proof mass portions collectively forming one proof mass. The entirety of the proof mass may contribute to detection of in-plane acceleration and out-of-plane acceleration. The MEMS accelerometers may detect in-plane and out-of-plane acceleration in a differential fashion. In response to out-of-plane accelerations, some MEMS accelerometers may experience butterfly modes, where one proof mass portion rotates counterclockwise relative to an axis while at the same time another proof mass portion rotates clockwise relative to the same axis. In response to in-plane acceleration, the proof mass portions may experience common translational modes, where the proof mass portions move in the plane along the same direction.

  • Patent number: 10628757
    Abstract: A system, method and computer program product for establishing and using a pollutant emission scavenging forecasting (PESF) model to calculate a purgeable pollutant emission to dynamically control an emitted pollutant at any target concentration. The dynamic control considers the initial pollutant concentration and pollutant scavenging ability of atmosphere. The method further takes into account the constraint conditions specified by a user, and employs a dynamic emission correction system to quickly calculate an optimal pollutant emission scheme. If the emission is lower than minimum acceptable value for a current time instance (a moment), the method corrects the emission intensity before (prior to) this moment by changing the initial concentration at this time. This initial concentration is the final pollutant concentration of a prior moment.
