A Partitioning Algorithm for Markov Decision Processes with Applications to Market Microstructure
"We propose a partitioning algorithm to solve a class of linear-quadratic Markov
decision processes with inequality constraints and nonconvex stagewise cost; within each
region of the partitioned state space, the value function and the optimal policy have analytical quadratic and linear forms, respectively..."

Gaussian process-based algorithmic trading strategy identification
"In particular, we model trader behaviour in terms of a Markov decision process. We infer the reward (or objective) function for
this process from observations of trading actions using a process from machine learning known as inverse reinforcement learning (IRL). The reward functions learned through IRL then constitute a feature space that can be the basis for supervised learning (for classification or recognition of traders) or unsupervised learning (for categorization of traders)..."

Teaching Inverse Reinforcement Learners via Features and Demonstrations
Learning near-optimal behaviour from an expert's demonstrations typically relies on the assumption that the learner knows the features that the true reward function depends on. In this paper, we study the problem of learning from demonstrations in the setting where this is not the case, i.e., where there is a mismatch between the worldviews of the learner and the expert. We introduce a natural quantity, the teaching risk, which measures the potential suboptimality of policies that look optimal to the learner in this setting. We show that bounds on the teaching risk guarantee that the learner is able to find a near-optimal policy using standard algorithms based on inverse reinforcement learning. Based on these findings, we suggest a teaching scheme in which the expert can decrease the teaching risk by updating the learner's worldview, and thus ultimately enable her to find a near-optimal policy.
