Multivariate Harmonic Distillation

Background: Time Series Forecasting (TSF) relies on capturing both local temporal patterns and global structures like periodicity.

Question / Future Work: Investigating the extension of the Harmonic Dataset Distillation (HDT) framework to multivariate time series where channels exhibit complex interdependencies, ensuring that the frequency-domain matching correctly accounts for cross-channel correlation structures alongside intra-channel harmonic information.
