چکیده
Multidimensional times series prediction is a challenging task. Only recently the increased data availability has made it possible to tackle with such problems. In this work we devised novel method exploit multiple correlated features in time series. The recurrent neural networks and wavelet transform have been important innovations fields of signal processing prediction. This paper proposes Wavelet Recurrent Network for multi-steps ahead multidimensional proposed model combines these two elements into network that predicts samples future are steps respect input samples. carries out multiresolution decomposition through transform, coefficients transforms output back domain. applied satellite telemetry data, composed readings from sensors which highly correlated. telemetries can help engineers detect anomalies system, that, context space missions, particularly dangerous since they compromise entire mission if not handled properly. results show outperforms without both terms accuracy width forecast horizon. • RNN Transform unique network. Exploits Overcomes traditional analytical numerical models, more expensive. Yields medium-term forecasts an high accuracy. Outperforms simple

in this study the wavelet neural network (wnn) and artificial neural network (ann) were used to simulate barley breakage percentage in combine harvester. the models have been trained using the same data conditions. air temperature, thresher cylinder speed, distance between thresher cylinder and concave (back and forth) and the percentage of barely moisture were as the input variables. the resul...
متن کاملRecurrent neural networks for time-series prediction
Recurrent neural networks have been used for time-series prediction with good results. In this dissertation we compare recurrent neural networks with time-delayed feed forward networks, feed forward networks and linear regression models to see which architecture that can make the most accurate predictions. The data used in all experiments is real-world sales data containing two kinds of segment...
متن کاملSequential Recurrent Neural Networks for Language Modeling
Feedforward Neural Network (FNN)-based language models estimate the probability of the next word based on the history of the last N words, whereas Recurrent Neural Networks (RNN) perform the same task based only on the last word and some context information that cycles in the network. This paper presents a novel approach, which bridges the gap between these two categories of networks. In partic...

In this paper we propose an approach to solving the problems of forecasting multivariate time series telemetry data that describe the state of small airborne objects. The main objective of the proposed method it's automated design and development of neural network models for solving such problems, namely the choice of model parameters are close to optimal. The approach is based on the use of en...
متن کاملCombining Neural Network and Wavelet Transform to Predict Drought in Iran Using MODIS and TRMM Satellite Data
The drought can be described as a natural disaster in each region. In this study, one of the important factors in drought, vegetation, has been considered. For this purpose, monthly vegetation cover images and snow cover data of MODIS and TRMM satellite precipitation product from 2009 to 2018 were used for the study area of Iran. After initial preprocessing, we have used artificial neural netwo...
