A diffusion-based generative model for financial time series via geometric Brownian motion
Gihun Kim, Sun-Yong Choi, Yeoneung Kim
We propose a novel diffusion-based generative framework for financial time series that incorporates geometric Brownian motion (GBM), the foundation of the Black--Scholes theory, in…

Approximate Thompson Sampling for Learning Linear Quadratic Regulators with Regret
Yeoneung Kim, Gihun Kim, Jiwhan Park +1
We propose a novel Thompson sampling algorithm that learns linear quadratic regulators (LQR) with a Bayesian regret bound of . Our method leverages Langevin dynamics w…
