Research on the Prediction Method of Stock Price Based on RBF Neural Network Optimization Algorithm

With the development of social economy, people pay more and more attention to investment and financial management. However, due to the strong volatility of the stock market, it is difficult to accurately predict the future trend of stock and the investment risk is very high. This paper proposes an optimization algorithm based on RBF neural network to predict the stock price. On the basis of RBF neural network, K-means clustering algorithm is introduced to optimize the network parameters, improve the training speed and prediction accuracy of the algorithm, and set corresponding evaluation indexes to evaluate the performance of the algorithm. The method proposed in this paper is applied to the stock prediction of stock market, and the closing price of several stocks in a period of time is predicted. The experimental results show that the method proposed in this paper has better prediction accuracy than other methods, and it is practical in the field of stock prediction.
