arXiv:2604.05543v2 Announce Type: replace Abstract: Multivariate time series forecasting often struggles to capture long-range dependencies due to fixed lookback windows. Retrieval-augmented forecasting addresses this by retrieving historical segments from memory, but existing approaches rely on a channel-agnostic strategy that applies the same references to all variables. This neglects inter-variable heterogeneity, where different channels exhibit distinct periodicities and spectral profiles. We propose CRAFT (Channel-wise retrieval-augmented forecasting), a novel framework that performs retr
The increasing complexity and dimensionality of real-world time series data for AI models are pushing research towards more nuanced and efficient forecasting methods.
Improved multivariate time series forecasting, especially with channel-specific understanding, is critical for optimizing operations, predictive maintenance, and resource allocation across many industries.
New methods for time series forecasting will allow AI agents and autonomous systems to make more accurate and tailored predictions across diverse data streams, moving beyond 'one-size-fits-all' approaches.
