چکیده
Ensuring the best possible stability of UTC(k) (local time scale) and its compliance with UTC scale (Universal Coordinated Time) forces predicting [UTC-UTC(k)] deviations, article presents results work on two methods constructing series (TS) for a neural network (NN), increasing accuracy prediction. In first method, prepared TSs are based deviations determined according to 5-day interval. order improve PCHIP interpolating function is used in subsequent TSs, obtaining TS elements 1-day A limitation improvement prediction these has been too large horizon. The introduction 2012 additional Rapid by BIPM makes it shorten horizon, building proposed second method. Each them consists subsets. subset scale, scale. research field Polish Timescale means GMDH-type NN shows that achieved built

Some New Methods for Prediction of Time Series by Wavelets
Extended Abstract. Forecasting is one of the most important purposes of time series analysis. For many years, classical methods were used for this aim. But these methods do not give good performance results for real time series due to non-linearity and non-stationarity of these data sets. On one hand, most of real world time series data display a time-varying second order structure. On th...
متن کاملTuberculosis incidence predicting system using time series neural network in Iran
Background: Tuberculosis (TB) is an important infectious disease with high mortality in the world. None of the countries stay safe from TB. Nowadays, different factors such as Co-morbidities, increase TB incidence. World Health Organization (WHO) last report about Iran's TB status shows rising trend of multidrug-resistant tuberculosis (MDR-TB) and HIV/TB. More than 95% illness and death of TB c...
متن کاملVehicle's velocity time series prediction using neural network
This paper presents the prediction of vehicle's velocity time series using neural networks. For this purpose, driving data is firstly collected in real world traffic conditions in the city of Tehran using advance vehicle location devices installed on private cars. A multi-layer perceptron network is then designed for driving time series forecasting. In addition, the results of this study are co...
