Modeling time series by aggregating multiple fuzzy cognitive maps [PDF]

open access: yesPeerJ Computer Science, 2021
Background The real time series is affected by various combinations of influences, consequently, it has a variety of variation modality. It is hard to reflect the variation characteristic of the time series accurately when simulating time series only by ...

The complex set of internal repeats in SpTransformer protein sequences result in multiple but limited alternative alignments

open access: yesFrontiers in Immunology, 2022
The SpTransformer (SpTrf) gene family encodes a set of proteins that function in the sea urchin immune system. The gene sequences have a series of internal repeats in a mosaic pattern that is characteristic of this family.

Ultra-short-term load prediction of integrated energy system based on load similar fluctuation set classification

open access: yesFrontiers in Energy Research, 2023
Due to the strong coupling characteristics and daily correlation characteristics of multiple load sequences, the prediction method based on time series extrapolation and combined with multiple load meteorological data has limited accuracy improvement ...

Empirical adaptive wavelet decomposition (EAWD): an adaptive decomposition for the variability analysis of observation time series in atmospheric science [PDF]

open access: yesNonlinear Processes in Geophysics, 2022
Most observational data sequences in geophysics can be interpreted as resulting from the interaction of several physical processes at several timescales and space scales. In consequence, measurement time series often have characteristics of non-linearity

Mixture Hidden Markov Models for Sequence Data: The seqHMM Package in R

open access: yesJournal of Statistical Software, 2019
Sequence analysis is being more and more widely used for the analysis of social sequences and other multivariate categorical time series data. However, it is often complex to describe, visualize, and compare large sequence data, especially when there are

An Attention Encoder-Decoder Dual Graph Convolutional Network with Time Series Correlation for Multi-Step Traffic Flow Prediction

open access: yesJournal of Advanced Transportation, 2022
Accurate traffic prediction is a powerful factor of intelligent transportation systems to make assisted decisions. However, existing methods are deficient in modeling long series spatio-temporal characteristics. Due to the complex and nonlinear nature of

Multineuronal Spike Sequences Repeat with Millisecond Precision

open access: yesFrontiers in Neural Circuits, 2013
Cortical microcircuits are nonrandomly wired by neurons. As a natural consequence, spikes emitted by microcircuits are also nonrandomly patterned in time and space.

ClickClust: An R Package for Model-Based Clustering of Categorical Sequences

open access: yesJournal of Statistical Software, 2016
The R package ClickClust is a new piece of software devoted to finite mixture modeling and model-based clustering of categorical sequences. As a special kind of time series, categorical sequences, also known as categorical time series, exhibit a time ...

ON \(\Lambda\)-CONVERGENCE ALMOST EVERYWHERE OF MULTIPLE TRIGONOMETRIC FOURIER SERIES

open access: yesUral Mathematical Journal, 2017
We consider one type of convergenceĀ of multiple trigonometric Fourier seriesĀ intermediate between the convergence over cubes and the \(\lambda \)-convergenceĀ for \(\lambda >1\).
