VFEM: Visual Feature Empowered Multivariate Time Series Forecasting with Cross-Modal Fusion

Researchers present VFEM, a cross-modal forecasting model that combines pre-trained vision models with time series data to improve multivariate forecasting by capturing cross-channel dependencies. The approach transforms time series into visual representations and uses cross-modal attention fusion, achieving competitive performance while training only 7.45% of total parameters.

Unicorn: Scaling High-Dimensional Time Series Forecasting via Universal Correlation Modeling

Researchers introduce Unicorn, a universal correlation network that addresses a key limitation in time series forecasting by enabling models to scale across high-dimensional datasets while capturing inter-channel dependencies. The framework uses a latent prototype codebook to learn identity-agnostic patterns that transfer across diverse domains, significantly outperforming existing architectures in few-shot transfer scenarios.
