Application of Attention-Based LSTM Hybrid Models for Stock Price Prediction

The stock market plays a pivotal role in the national economy, while the application of artificial intelligence (AI) in stock price prediction has gained traction. This paper evalu-ates the performance of five advanced deep learning (DL) models: Long Short-Term Memory (LSTM), Self-attention, Convolutional Neural Network-LSTM with attention (CNN-LSTM-attention), Gated Recurrent Unit-LSTM with attention (GRU-LSTM-attention), and CNN-Bidirectional LSTM-GRU with attention (CNN-BiLSTM-GRU-attention), utilizing a decade of data on Amazons closing prices. Our results show that the CNN-BiLSTM-GRU-attention model exhibits superior performance, achieving a root mean square error (RMSE) of 1.054589 and a coefficient of determination (R2) of 0.970123, indicative of its proficiency in handling intricate financial data. This papers significance lies in its validation of the effectiveness of attention-based ensemble models in stock market prediction, as well as the introduction of the innovative application of the CNN-BiLSTM-GRU-attention model in financial forecast-ing, which holds potential for wide-ranging applicability.
