High-order statistics
WebApr 23, 2024 · One of the first steps in exploratory data analysis is to order the data, so order statistics occur naturally. In particular, note that the extreme order statistics are x ( 1) = min {x1, x2…, xn}, x ( n) = max {x1, x2, …, xn} The sample range is r = x ( n) − x ( 1) and the sample midrange is r 2 = 1 2[x ( n) − x ( 1)]. WebRadiomic data contain first-, second-, and higher-order statistics. These data are combined with other patient data and are mined with sophisticated bioinformatics tools to develop models that may potentially improve diagnostic, prognostic, and predictive accuracy.

WebSep 1, 2010 · Higher order spectra, also known as polyspectra, are spectral representations of higher order statistics, i.e. moments and cumulants of third order and beyond. HOS (higher order statistics or higher order spectra) can detect deviations from linearity, stationarity or Gaussianity in the signal.

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. Web3.1 What is the High-order Statistics? The BERT [5] model and its pre-trained successors utilize the self-attention, like GPT-3 [2] and switch Transformer [7], and they achieve …
WebFeb 4, 2012 · Polyspectra blind deconvolution approaches utilize the higher-order statistics (moments and cumulants of order greater than two) of the observed signal { y ( n )} to identify the characteristics of the channel impulse response { f ( k )} or the equalizer { u ( k )}. Let us consider the linear filtering model with additive noise, that is: (29) 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.
