Paper Review: HGTS‑Former – A Hierarchical Hypergraph Transformer for Multivariate Time‑Series Analysis

The HGTS‑Former model introduces a hierarchical hypergraph backbone combined with a Transformer to capture high‑order and dynamic dependencies in multivariate time‑series data, and experimental results on eight datasets show it consistently outperforms state‑of‑the‑art methods in both long‑term forecasting and interpolation tasks.
