Ananda Chatterjee, Hrisav Bhowmick, Jaydip Sen For a long-time, researchers have been developing a reliable and accurate predictive model for stock price prediction. According to the literature, if …
Stock price prediction is an important topic in finance and economics which has spurred the interest of researchers over the years to develop better predictive models. The autoregressive integrated moving average (ARIMA) models have been explored in literature for time series prediction. This paper pre...
SVM model is verified by the experiments.Experimental results show that,compared with traditional stock forecast method,the forecasting precision of CAR-SVM model of is high,and the stock price changes to reflect the nonlinear dynamic rule.It has wide application prospects in stock price prediction....
In this paper, based on stock market predictability and quantify some of the influencing factors on the stock market is built based on Matlab's stock price prediction model, and part of the large-cap stocks, stocks closing price forecasting, evaluation to predict the effectiveness of the model....
The results showed that adding lexicon based twitter sentiment scores as additional inputs to other company stock variables for stock price prediction improved the prediction accuracy and resulted to a more accurate NARX model. 展开 关键词: artificial neural networks accuracy sentiment scores Sentiword...

Stock price prediction has been regarded as an intractable task due to the intrinsic nonlinearity and instability of stock market.In this paper,based on the traditional SVR approach,a forecasting model that integrates principal component analysis(PCA)and fruit fly optimization algorithm(FOA)for predictin...
However, these strategies do not usually guarantee good returns because they guide on trends and not the most likely price. It is therefore necessary to explore improved methods of prediction. The research proposes the use of Artificial Neural Network that is feedforward multi-layer perceptron with...
