Dynamic Universal Approximation via Signature Controlled Differential Equations
Tomás Carrondo, Christa Cuchiero, Paul P. Hager +1
The paper introduces signature controlled differential equations (Sig‑CDEs) and shows that they can universally approximate any well‑posed path‑dependent controlled differential eq…
The Volterra signature
Paul P. Hager, Fabian N. Harang, Luca Pelizzari +1
Modern approaches for learning from non-Markovian time series, such as recurrent neural networks, neural controlled differential equations or transformers, typically rely on implic…
Computational aspects of the Volterra Signature
Paul P. Hager, Fabian N. Harang, Luca Pelizzari +1
The Volterra signature extends the classical path signature by incorporating general matrix-valued kernel into its iterated integral structure, yielding a flexible notion of memory…
Stochastic Analysis of Overlapping Generations Models Under Incomplete Markets
Cangxiong Chen, Sigmund Ellingsrud, Fabian Harang +2
We provide a stochastic analysis of an overlapping-generations model under incomplete markets. By casting individual optimisation with idiosyncratic income risk into a forward-back…
