Gold Price Prediction Based on LSTM-Attention Combined Model

Junping Wu, Jihua Liu
This paper explores effective methods for predicting gold prices, proposing three modeling strategies: a standalone Long Short-Term Memory (LSTM) network, a Convolutional Self-Attention (CSA) Network, and a combination model of both. Through empirical analysis, we systematically compare the performance of these three models in gold price forecasting, with a focus on evaluating their predictive accuracy. The experimental results indicate that the LSTM-Attention combination model significantly out...
