The novel composite forecasting framework introduced in this study integrates variational mode decomposition (VMD), PatchTST, and adaptive scale-weighted layer (ASWL) to address the critical need for accurate stock index price forecasting. The proposed method first decomposes raw price series into intrinsic mode functions (IMFs) using VMD, then models each IMF with PatchTST to capture temporal patterns effectively. The ASWL module is applied to incorporate scale information, enhancing prediction accuracy. The final forecast is derived by aggregating predictions from all IMFs. The framework demonstrates significant improvements in forecasting accuracy compared to traditional models, showing robust performance across different stock indices.

This study introduces a new way to predict stock index prices using a combination of techniques. It’s like breaking down a puzzle into smaller pieces and then reassembling them to get a more accurate picture. The method uses something called variational mode decomposition (VMD) to split the price data into different components, and then uses another technique called PatchTST to model each component. It also includes an adaptive scale-weighted layer (ASWL) to help make the predictions more accurate. The study shows that this approach can be used to predict stock index prices with greater accuracy than traditional methods.
