Researchers have developed SpecTF, a novel framework for multimodal time-series forecasting that effectively integrates textual context with numerical data. Unlike previous methods that align text and time-series step-by-step, SpecTF leverages spectral decomposition to analyze time series in the frequency domain. This approach captures both short-term changes and long-term trends, allowing for a more nuanced fusion of textual relevance with temporal patterns. The framework uses a lightweight cross-attention mechanism to adaptively reweight frequency bands based on textual input before generating predictions, demonstrating significant performance improvements over existing state-of-the-art models with fewer parameters.
