Longer-Period Cycle Verification

Background: Time series forecasting models that utilize frequency domain analysis often focus on low-frequency components, potentially overlooking higher frequency information critical for capturing short-term fluctuations.

Question / Future Work: The authors mention that current experiments with MFreqCycle have verified the feasibility of incorporating weekly cycles due to dataset limitations but state that longer-period patterns, such as annual cycles, remain unverified. Future work should explore the integration and effectiveness of modeling even longer-period seasonalities like annual cycles within the MFreqCycle framework to fully address multi-scale periodicity.
