WebOct 11, 2024 · Download PDF Abstract: We aim at capturing high-order statistics of feature vectors formed by a neural network, and propose end-to-end second- and higher-order pooling to form a tensor descriptor. Tensor descriptors require a robust similarity measure due to low numbers of aggregated vectors and the burstiness phenomenon, when a given … WebHigher order spectra (also known as polyspectra), defined in terms of higher order statistics (“cumulants”) of a signal, do contain such information. Particular cases of higher order spectra are the third-order spec- trum also called the bispectrum which is, by definition, the Fourier transform of the third-order statistics, and

WebAbstract. Purpose In this chapter, we present a few basic notions about higher order statistics that generalise notions defined above for second order statistics. We show, in particular, how the definition of the spectral representation of a process can be generalised for processes that are stationary at orders higher than two. 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.
