FreSH: Frequency-Segmented Hierarchical Multi-Expert Framework for Multivariate Time Series Classification

IJCAI 2026

Multivariate Time Series Classification (MTSC) demands models that can effectively capture complex temporal patterns across multiple scales while remaining computationally efficient. However, existing approaches generally struggle to reconcile fine-grained representation learning, especially under c

Considering Nonstationary within Multivariate Time Series with Variational Hierarchical Transformer for Forecasting

AAAI 2024technical

The forecasting of Multivariate Time Series (MTS) has long been an important but challenging task. Due to the non-stationary problem across long-distance time steps, previous studies primarily adopt stationarization method to attenuate the non-stationary problem of original series for better predict…
