A Non-linear Function-on-Function Model for Regression with Time Series Data

no code implementations24 Nov 2020 Qiyao Wang, HaiYan Wang, Chetan Gupta, Aniruddha Rajendra Rao, Hamed Khorasgani

Specifically, we aim to learn mathematical mappings from multiple chronologically measured numerical variables within a certain time interval S to multiple numerical variables of interest over time interval T. Prior arts, including the multivariate regression model, the Seq2Seq model, and the functional linear models, suffer from several limitations.
