High-order statistics
WebHigh-order moments are moments beyond 4th-order moments. As with variance, skewness, and kurtosis, these are higher-order statistics, involving non-linear combinations of the data, and can be used for description or estimation of further shape parameters. WebNow, we move on to consider the higher-order capacity statistics for κ-µ shadowed fading channels. As a first step, the case of i.i.d. κ-µ shadowed fading channel is investigated. Theorem 3. The higher-order capacity statistics of spectrum aggregation systems over i.i.d. κ-µ shadowed fading channels can be expressed as Λn = µM (1+κ ...

It appears that these cross moments allow for ordered directional matching …
WebAn automated detection system using nonlinear higher order statistics (HOS) based method is used to capture the detailed information present in the fundus image efficiently. The center slice of bispectrum and bicepstrum are applied on fundus images. Various features are extracted from the diagonal of these central slices. WebDirection finding algorithms based on high-order statistics. Abstract: Two direction finding algorithms are presented for nonGaussian signals, which are based on the fourth-order cumulants of the data received by the array. The first algorithm is similar to MUSIC, while the second is asymptotically minimum variance in a certain sense.
Web3. Multi-task learning with high-order statistics 3.1. High-order statistics Higher-order statistics can be used in estimation of the shape of unimodal distributions and have been applied to many tasks [14, 15, 16].
