Local regression on path spaces with signature metrics
Christian Bayer, Davit Gogolashvili, Luca Pelizzari
We study nonparametric regression and classification for path-valued data. We introduce a functional Nadaraya-Watson estimator that combines the signature transform from rough path…

Pricing American options under rough volatility using deep-signatures and signature-kernels
Christian Bayer, Luca Pelizzari, Jia-Jie Zhu
We extend the signature-based primal and dual solutions to the optimal stopping problem recently introduced in [Bayer et al.: Primal and dual optimal stopping with signatures, to a…

Primal and dual optimal stopping with signatures
Christian Bayer, Luca Pelizzari, John Schoenmakers
We propose two signature-based methods to solve the optimal stopping problem - that is, to price American options - in non-Markovian frameworks. Both methods rely on a global appro…
