arXiv:2605.15690v2 Announce Type: replace Abstract: Accurate and efficient long-term multivariate time series forecasting requires capturing recurring temporal structure while keeping inference cheap across many variables and horizons. Frequency-space models represent long-range and periodic variation compactly, but they typically process the real and imaginary spectral components as weakly coupled streams and treat periodic cues as ordinary input features, even when such cues are unreliable. This paper proposes FRWKV-Plus, a lightweight periodic-aware frequency-space forecasting model built o
This research is published as AI models continue to push the boundaries of efficiency and accuracy in complex data analysis, particularly in time series forecasting.
Improved time series forecasting directly enhances predictive analytics across many industries, from finance to resource management, and underpins more sophisticated AI agentic systems.
New models like FRWKV-Plus could make long-term multivariate time series forecasting more efficient and accurate, especially for periodic data, by processing spectral components more effectively.
