  • Patent number: 11914937
    Abstract: Techniques, systems, and devices are described for providing a computational frame for estimating high-dimensional stochastic behaviors. In one exemplary aspect, a method for performing numerical estimation includes receiving a set of measurements of a stochastic behavior. The set of correlated measurements follows a non-standard probability distribution and is non-linearly correlated. Also, a non-linear relationship exists between a set of system variables that describes the stochastic behavior and a corresponding set of measurements. The method includes determining, based on the set of measurements, a numerical model of the stochastic behavior. The numerical model comprises a feature space comprising non-correlated features corresponding to the stochastic behavior. The non-correlated features have a dimensionality of M and the set of measurements has a dimensionality of N, M being smaller than N.

  • Publication number: 20230353158
    Abstract: This application is directed to frequency controlling in an electronic device that includes a selector, a clock generated, and a controller. The selector selects one of a first reference signal and a second reference signal as an input signal having an input phase. The clock generator receives the input signal and generates a periodic signal, and the periodic signal has an output phase that matches the input phase of the input signal. While the first reference signal is selected as the input signal, the controller identifies a temporal range including a peak instant at which the second reference signal reaches a peak frequency, select a switching instant within the temporal range based on a known temporal position of the peak instant with respect to the temporal range, and control the selector to select the second reference signal as the input signal at the switching instant.
