Forecasting high-dimensional functional time series with dual-factor structures
Chen Tang, Han Lin Shang, Yanrong Yang +1
We propose a dual-factor model for high-dimensional functional time series (HDFTS) that considers multiple populations. The HDFTS is first decomposed into a collection of functiona…

Feature Extraction for Functional Time Series: Theory and Application to NIR Spectroscopy Data
Yang Yang, Yanrong Yang, Han Lin Shang
We propose a novel method to extract global and local features of functional time series. The global features concerning the dominant modes of variation over the entire function do…
