Nowcasting with signature methods

2 code implementations17 May 2023 Samuel N. Cohen, Silvia Lui, Will Malpass, Giulia Mantoan, Lars Nesheim, Áureo de Paula, Andrew Reeves, Craig Scott, Emma Small, Lingyi Yang

We look at the nowcasting problem by applying regression on signatures, a simple linear model on these nonlinear objects that we show subsumes the popular Kalman filter.

Neural Controlled Differential Equations for Online Prediction Tasks

2 code implementations21 Jun 2021 James Morrill, Patrick Kidger, Lingyi Yang, Terry Lyons

This is fine when the whole time series is observed in advance, but means that Neural CDEs are not suitable for use in \textit{online prediction tasks}, where predictions need to be made in real-time: a major use case for recurrent networks.
