Title: Learning Dynamic Processes with Reservoir Computing
Host: TT.-Prof. Dr. Tobias Sutter
Abstract: Many dynamic problems in engineering, control theory, signal processing, time series analysis,
and forecasting can be described using input/output (IO) systems. Whenever a true functional IO relation
cannot be derived from first principles, parsimonious and computationally efficient state-space systems can
be used as universal approximants. We have shown that Reservoir Computing (RC) state-space systems
with simple and easy-to-implement architectures enjoy universal approximation properties proved in different
setups. The defining feature of RC systems is that some components (usually the state map) are randomly
generated, and the observation equation is of a tractable form. From the machine learning perspective, RC
systems can be seen as recurrent neural networks with random weights and a simple-to-train readout layer
(often a linear map). RC systems serve as efficient, randomized, online computational tools for learning
dynamic processes and enjoy generalization properties that can be explicitly derived. We will make a general
introduction to up-to-date theoretical developments, discuss connections with research contributions in
other fields, and address details of RC systems’ applications.

Title: Quantum Monte Carlo algorithm for solving Black-Scholes PDEs for high-dimensional option pricing in finance and its complexity analysis
Host: TT.-Prof. Dr. Tobias Sutter
Abstract: In this talk we present a quantum Monte Carlo algorithm to solve high-dimensional Black-Scholes PDEs
with correlation for high-dimensional option pricing. The payoff function of the option is of general form and is
only required to be continuous and piece-wise affine (CPWA), which covers most of the relevant payoff functions
used in finance. We provide a rigorous error analysis and complexity analysis of our algorithm. In particular,
we prove that the computational complexity of our algorithm is bounded polynomially in the space dimension d
of the PDE and the reciprocal of the prescribed accuracy ε. Moreover, we show that for payoff functions which
are bounded, our algorithm indeed has a speed-up compared to classical Monte Carlo methods. Furthermore,
we present numerical simulations in one and two dimensions using our developed package within the Qiskit
framework tailored to price CPWA options with respect to the Black-Scholes model, as well as discuss the
potential extension of the numerical simulations to arbitrary space dimension.
This talk is based on joint work with Jianjun Chen and Yongming Li
