Researchers have introduced QiYao-I, a new foundation model designed to tackle the complexities of irregular multivariate time series forecasting. Unlike existing models that often assume regular sampling, QiYao-I incorporates a novel sampling-conditioned temporal manifold attention mechanism to better capture irregular time intervals and asynchronous dependencies between variables. The model also features a dynamic variable interaction mechanism that is frequency-aware, allowing for selective cross-variable communication even with asynchronous observations. Experiments on real-world benchmarks indicate that QiYao-I outperforms current time series foundation models and end-to-end irregular forecasting models, demonstrating strong zero-shot and few-shot generalization capabilities.
