Researchers have introduced WorldTS, a novel framework for time series forecasting that enhances prediction accuracy by incorporating multimodal external factors. Unlike traditional methods that map historical observations directly to future ones, WorldTS models latent-space dynamics. This approach allows external information, such as multimodal covariates, to directly influence the formation and evolution of these latent states. The framework employs a two-stage training process: first, it learns forecasting-relevant latent state dynamics conditioned on covariates, and second, it trains an observation decoder to map predicted states back to observable future values. Experiments across 21 real-world datasets demonstrate the effectiveness of WorldTS. AI
