Short-Period Information in GPS Time Series

Assessment of Multiscale Information for Short Physiological Time Series

This paper presents a multiscale information measure of Electroencephalogram (EEG) for analysis with a short data length. A multiscale extension of permutation entropy (MPE) is capable of fully reflecting the dynamical characteristics of EEG across different temporal scales. However, MPE yields an imprecise estimation due to coarse-grained procedure at large scales. We present an improved MPE m...

APT: Approximate Period Detection in Time Series

Period detection from time series is an important problem with many real-world applications such as weather forecast, stock market predictions, electrocardiogram analysis, periodic disease outbreak. In this work, we present a novel approximate period detection method for time series. The simplicity of our algorithm and its adaptability for high dimensional datasets using renowned tools and tech...

High-order Ionospheric Effects on GPS Coordinate Time Series

Algebraic Evolutionary Forecasting of Short Time Series

A new short-term time series forecasting method based on the identification of skeleton algebraic sequences is proposed in this paper. The concept of the rank of the Hankel matrix is exploited to detect a base fragment of the time series and to extrapolate the model of the process into future. Evolutionary algorithms are used to remove the noise, to identify the skeleton algebraic sequence and ...
