    摘要: A method of performing anisotropic texture filtering includes generating one or more parameters describing an elliptical footprint in texture space; performing isotropic filtering at each of a plurality of sampling points in an ellipse to be sampled, the ellipse to be sampled based on the elliptical footprint; and combining results of the isotropic filtering at each of the plurality of sampling points to generate a combination result by a sequence of linear interpolations, wherein each linear interpolation in the sequence of linear interpolations comprises blending a result of a previous linear interpolation in the sequence with the isotropic filtering results for one or more of the plurality of sampling points, the one or more of the plurality of sampling points for a linear interpolation being closer to a midpoint of the major axis of the elliptical footprint than the one or more of the plurality of sampling points for the previous linear interpolation in the sequence.

    摘要: The present disclosure generally relates to apparatus, software and methods for detecting anomalous elements in data. For example, the data can be any time series, such as but not limited to radio frequency data, temperature data, stock data, or production data. Each type of data may be susceptible to repeating phenomena that produce recognizable features of anomalous elements. In some embodiments, the features can be characterized as known patterns and used to train a machine learning model via supervised learning to recognize those features in a new data series.

    摘要: An operating method for a distribution output device includes; generating data number sets for data groups, grouping defect times according to an order in which the corresponding defects occurred in relation to each of the data number sets, calculating likelihood summations respectively corresponding to the data number sets in relation to defect times grouped in accordance with the data number sets, determining a maximum likelihood summation among the likelihood summations, determining optimal population parameter data for each of the data groups in relation to the maximum likelihood summation, and outputting a Weibull distribution for each of the data groups in relation to the optimal population parameter data for each of the data groups.
