WebThe definitions, properties, and computation of higher-order statistics and spectra, with emphasis on the bispectrum and trispectrum are presented. Parametric and nonparametric expressions for polyspectra of linear and nonlinear processes are described. The applications of higher-order spectra in signal processing are discussed.< > In statistics, the term higher-order statistics (HOS) refers to functions which use the third or higher power of a sample, as opposed to more conventional techniques of lower-order statistics, which use constant, linear, and quadratic terms (zeroth, first, and second powers). The third and higher moments, as used in the skewness and kurtosis, are examples of HOS, whereas the first and second moments, as used in the arithmetic mean (first), and variance (second) are examples of lo…

High-order Tensor Pooling with Attention for Action Recognition

WebThe algorithm first computes high-order statistics from the data. It resorts to using a TI, only if enough replicates could not be identified to determine the conditional probabilities. A shortcoming of the method is related to selecting the spatial cumulants. For example, suppose that four numbers are observed or recorded, resulting in a sample of size 4. If the sample values are 6, 9, 3, 8, the order statistics would be denoted where the subscript (i) enclosed in parentheses indicates the ith order statistic of the sample.
