GS-FUSE: Granger-Supervised Gated Fusion and Multi-Granularity Alignment for Event-Driven Financial Forecasting
TL;DR
Financial forecasting struggles to effectively combine multiple data sources (news, market data, events) while determining which signals truly influence outcomes. GS-FUSE introduces a gated fusion mechanism supervised by Granger causality—a statistical test identifying whether past values of one variable help predict another—plus multi-granularity alignment to synchronize data across different time scales.
✦ Why It Matters
Engineers can apply Granger-supervised fusion to any multi-source forecasting problem requiring principled signal weighting and temporal alignment.
Key Takeaways
- Utilize GS-FUSE for improved financial event forecasting accuracy.
- Incorporate causal analysis to determine predictive value of event text.
- Align high-level and detailed data for better market trajectory predictions.
- Adapt GS-FUSE with existing AI models for versatile applications.
How It Works
GS-FUSE employs a Granger-supervised gated fusion module that selectively integrates event text into the forecasting process only when it provides additional predictive power beyond historical price data. This causal-aware approach ensures that the model focuses on relevant information, while the multi-granularity alignment mechanism synchronizes different levels of data representation, enhancing the model's ability to predict future market movements.
