FATE: Focal-modulated Attention Encoder for Multivariate Time-series Forecasting
This addresses the challenge of reliable forecasting for climate phenomena, which is critical for mitigation strategies, though it appears incremental as it builds on existing transformer-based approaches.
The paper tackles the problem of accurate multivariate time-series forecasting for climate change monitoring by proposing FATE, a novel transformer architecture with focal modulation that captures spatiotemporal correlations. The result shows that FATE consistently outperforms all state-of-the-art methods across seven diverse real-world datasets.
Climate change stands as one of the most pressing global challenges of the twenty-first century, with far-reaching consequences such as rising sea levels, melting glaciers, and increasingly extreme weather patterns. Accurate forecasting is critical for monitoring these phenomena and supporting mitigation strategies. While recent data-driven models for time-series forecasting, including CNNs, RNNs, and attention-based transformers, have shown promise, they often struggle with sequential dependencies and limited parallelization, especially in long-horizon, multivariate meteorological datasets. In this work, we present Focal Modulated Attention Encoder (FATE), a novel transformer architecture designed for reliable multivariate time-series forecasting. Unlike conventional models, FATE introduces a tensorized focal modulation mechanism that explicitly captures spatiotemporal correlations in time-series data. We further propose two modulation scores that offer interpretability by highlighting critical environmental features influencing predictions. We benchmark FATE across seven diverse real-world datasets including ETTh1, ETTm2, Traffic, Weather5k, USA-Canada, Europe, and LargeST datasets, and show that it consistently outperforms all state-of-the-art methods, including temperature datasets. Our ablation studies also demonstrate that FATE generalizes well to broader multivariate time-series forecasting tasks.
