overview of physical reservoir computing

There's a new book on Reservoir Computng out from Springer, and it has lots of interesting chapters, including one from us:

Matthew Dale, Julian F. Miller, Susan Stepney, Martin Trefzer.
Reservoir Computing in Material Substrates.
in Kohei Nakajima, Ingo Fischer, eds, Reservoir Computing: Theory, Physical Implementations and Applications, pp.141–166. Springer, 2021.
doi:10.1007/978-981-13-1687-6_7

Abstract: We overview Reservoir Computing (RC) with physical systems from an Unconventional Computing (UC) perspective. We discuss challenges present in both fields, including encoding and representation, or how to manipulate and read information; ways to search large and complex configuration spaces of physical systems; and what makes a “good” computing substrate.

Reservoir Computingis an interesting area of unconventional computing, because it supports computing directly with a wide variety of different physical materials, so it is finding many novel applications.
