On learning higher-order cumulants in diffusion models [PDF]

open access: yesMachine Learning: Science and Technology
To analyse how diffusion models learn correlations beyond Gaussian ones, we study the behaviour of higher-order cumulants, or connected n -point functions, under both the forward and backward process.

Application of Higher Order Cumulants for Seismic Wavelet Reconstruction

open access: yesData Science Journal, 2007
According to the fact that high order cumulants (HOC) retain the phase information of signals and the HOC of the Gaussian color noise is always equal to zero, a new method of wavelet reconstruction is provided in this paper, based on 4th-order cumulants ...

Sliding window higher-order cumulants for detection of eye blink artifact from short segments of single-channel EEG [PDF]

open access: goldPeerJ Computer Science
Background The prevalence of single-channel electroencephalogram (EEG) is increasing. However, eye blink artifacts can contaminate EEG signals, potentially impacting their clinical utility.

Higher order net-baryon number cumulants and baryon-strangeness correlations: Comparing QCD results on the pseudo-critical line with RHIC-BES II results on the freeze-out line [PDF]

open access: greenEPJ Web of Conferences
We present lattice QCD results for ratios of net-baryon number cumulants along the pseudo-critical line and compare them with STAR measurements from the RHIC BES-II program.

Traffic Rate Network Tomography with Higher-Order Cumulants [PDF]

open access: greenNetworks, 2020
AbstractNetwork tomography aims at estimating source–destination traffic rates from link traffic measurements. This inverse problem was formulated by Vardi in 1996 for Poisson traffic over networks operating under deterministic as well as random routing regimes. In this article, we expand Vardi's second‐order moment matching rate estimation approach to

Higher order net-proton number cumulants dependence on the centrality definition and other spurious effects [PDF]

open access: green, 2017
We study the dependence of the normalized moments of the net-proton multiplicity distributions on the definition of centrality in relativistic nuclear collisions at a beam energy of $\sqrt{s_{\mathrm{NN}}}= 7.7$ GeV.

Causal Discovery with Latent Confounders Based on Higher-Order Cumulants [PDF]

open access: greenCoRR, 2023
Causal discovery with latent confounders is an important but challenging task in many scientific areas. Despite the success of some overcomplete independent component analysis (OICA) based methods in certain domains, they are computationally expensive and can easily get stuck into local optima.

On higher-order moment and cumulant estimation

open access: greenJournal of Statistical Computation and Simulation, 2019
Moments and cumulants are involved in statistical analysis for a wide range of fields. A natural and popular approach to moment and cumulant estimation is based on the sample average. However, it is well known that these sample estimates usually perform poorly.

On the neglecting of higher-order cumulants in EXAFS data analysis [PDF]

open access: bronzeJournal of Synchrotron Radiation, 2009
The cumulant expansion is one of the most powerful and useful methods for EXAFS data analysis, in which the higher-order cumulants allow to consider deviations from a simple Gaussian distribution. In this work, analytical expressions have been derived to show the effects of neglecting higher-order cumulants in EXAFS analysis by the ratio method.
