Reinforcement Learning for Risk-Sensitive Investment Management: a Free Energy--Entropy Duality Approach

Sebastien Lleo, Wolfgang Runggaldier

This paper develops a reinforcement-learning approach to continuous-time risk-sensitive benchmarked asset allocation in a partly model-based setting. The benchmarked problem does n…

Risk-Sensitive Investment Management via Free Energy-Entropy Duality

Sebastien Lleo, Wolfgang Runggaldier

We study a benchmarked risk-sensitive portfolio problem in a factor-based setting to bring together three strands of the literature: benchmarked risk-sensitive investment managemen…

Exploratory Randomization for Discrete-Time Risk-Sensitive Benchmarked Investment Management with Reinforcement Learning

Sebastien Lleo, Wolfgang Runggaldier

This paper bridges reinforcement learning (RL) and risk-sensitive stochastic control by introducing a tractable exploration mechanism for policy search in risk-sensitive portfolio…

Exploratory Randomization for Discrete-Time Linear Exponential Quadratic Gaussian (LEQG) Problem

Sebastien Lleo, Wolfgang Runggaldier

We investigate exploratory randomization for an extended linear-exponential-quadratic-Gaussian (LEQG) control problem in discrete time. This extended control problem is related to…
