Model of Stock Price Prediction Based on Learning Artificial Immune System

In traditional artificial immune algorithm, there is no differentiation in clone step and variation step, and BP neural network is prone to obtain local minimum value. This paper presents a hybrid model combining a learning artificial immune algorithm and BP algorithm for stock shares forecast and investment strategy analysis. This model overcomes the shortcomings of artificial immune algorithm in cloning antibody and antibody variation without differentiation, and adds the antibody learning function in the model, accelerating the convergence speed and accuracy of antibody optimization. The simulation results show that the stock price prediction model with learning artificial immune algorithm is superior to BP stock price prediction model in the stock price prediction accuracy and investment strategy.
