    摘要: The present invention extends to methods, systems, and computing system program products for dynamic correlation batch calculation for Big Data. Embodiments of the invention include calculating a correlation for a modified computation set based on a group of components calculated for the pre-modified computation set and one or more groups of components calculated for a computation set to be excluded from the pre-modified computation set and a computation set to be included in the pre-modified computation set, where the size of the to-be-included computation set may or may not be equal to the size of the to-be-excluded computation set. When the size of the to-be-excluded computation set is smaller than half the size of the pre-modified computation set, dynamic correlation batch calculation may reduce computations thereby increasing calculation efficiency, saving computation resources, and reducing computing system's power consumption.

    摘要: The present invention extends to methods, systems, and computing system program products for decrementally calculating simple linear regression coefficients for Big Data or streamed data. Embodiments of the invention include decrementally calculating one or more components of simple linear regression coefficients for a modified computation set based on the one or more components of simple linear regression coefficients calculated for a previous computation set and then calculating the simple linear regression coefficients for the modified computation set based on the decrementally calculated components. Decrementally calculating simple linear regression coefficients avoids visiting all data elements in the modified computation set and performing redundant computations thereby increasing calculation efficiency, saving computing resources and reducing computing system's power consumption.

    摘要: The present invention extends to methods, systems, and computing system program products for incrementally calculating covariance for Big Data or streamed data. Embodiments of the invention include incrementally calculating one or more components of a covariance for two modified computation subsets based on one or more components of the covariance calculated for two previous computation subsets and then calculating covariance based on the incrementally calculated components. Incrementally calculating the components of a covariance avoids visiting all data elements in the modified computation subsets and performing redundant computations thereby increasing calculation efficiency, saving computing resources and reducing computing system's power consumption.

    摘要: The present invention extends to methods, systems, and computing system program products for iteratively calculating a Z-score for Big Data. Embodiments of the invention include iteratively calculating one or more components of a Z-score for a modified computation subset based on the one or more components of a Z-score calculated for a previous computation subset and then calculating a Z-score for a selected data element in the modified computation subset based on one or more of the iteratively calculated components. Iteratively calculating a Z-score avoids visiting all data elements in the modified computation subset and performing redundant computations thereby increasing calculation efficiency, saving computing resources and reducing computing system's power consumption.

    摘要: The present invention extends to methods, systems, and computing system program products for iteratively calculating a skewness for streamed data. Embodiments of the invention include iteratively calculating one or more components of skewness in an adjusted computation window based on the one or more components of the skewness calculated for a previous computation window and then calculating the skewness based on the iteratively calculated components. Iteratively calculating skewness avoids visiting all data elements in the computation window and performing redundant computations thereby increasing calculation efficiency, saving computing resources and reducing computing system power consumption.
