vector regression neural networks fSVR-NN)was proposed.Firstly,support vector regression approach was applied to
determine initial structure and initial weights of SVR.NN SO that the number of hidden layer nodes can be constructed
adaptively based on support vectors.Furthermore,an annealing robust learning algorithm was further presented to fine
tune the hidden node parameters and weights of SVR一ⅣM The adaptive SVR.NN has faSt convergence speed and robust
capability.and it can also suppress the ‘orerfitting’phenomena when the train data ncludes outliers.The adaptive
SVR.NN was then applied to time series prediction.Experimental results show that the adaptive SVR.ⅣⅣ can accurately
predict chaotic time series,and it iS valuable in both theory and application aspects. Platform: |

Description: Neural Network OCR.
There are many different approaches to optical character recognition problem. One of the most common and popular approaches is based on neural networks, which can be applied to different tasks, such as pattern recognition, time series prediction, function approximation, clustering, etc.
In this article, I ll try to review some approaches for optical character recognition using artificial neural networks. The attached project is aimed as a research project, so don t try to find here a ready solution for scanned document processing.

Description: Multi-step-prediction of chaotic time series based
on co-evolutionary recurrent neural network
协同进化递归神经网络的多步混沌时间序列预测-This paper proposes a co-evolutionary recurrent neural network (CERNN) for the multi-step-prediction of chaotic
time series, it estimates the proper parameters of phase space reconstruction and optimizes the structure of recurrent
neural networks by co-evolutionary strategy. The searching space was separated into two subspaces and the individuals
are trained in a parallel computational procedure. It can dynamically combine the embedding method with the capability
of recurrent neural network to incorporate past experience due to internal recurrence. The eff ectiveness of CERNN is
evaluated by using three benchmark chaotic time series data sets: the Lorenz series, Mackey–Glass series and real-world
sun spot series. The simulation results show that CERNN improves the performances of multi-step-prediction of chaotic
time series. Platform: |

SVM模型比标准的L§SVM明显提高了鲁棒性,可较好地实现时间序列数据的多步预测.-The neural network gas prediction model is poor in generalization performance and
easy in fafling into the local optimal value.In order to overcome these shortcomings,we pro—
pose the time series gas prediction method of least squares support vector machine(L§SVM).
However,in the LS-SVM case,the sparseness and robustness may lose,and the estimation of
the support values iS optimal only in the case of a Gaussian distribution of the error variables.
So,this paper proposes the weighted L孓SVM tO overcome these tWO drawbacks.Meanwhile,
the optimal embedding dimension and delay time of time series are obtained by the smallest dif—
ferential entropy method.On this basis,multi-step time series prediction algorithm steps are
given based on the weighted LS-SVM.Finally,the data of gas outburst in working face of Hebi
lOth mine iS adopted to validate this model.The results show that the predict effect of shortterm
