Statistically Assuring Safety of Control Systems using Ensembles of Safety Filters and Conformal Prediction

A recent study published on arXiv explores the integration of cognitive biases into reinforcement learning (RL) frameworks for financial decision-making, highlighting how human behavior influenced by biases like overconfidence and loss aversion can affect trading strategies. The research aims to demonstrate that RL models incorporating these biases can achieve better risk-adjusted returns compared to traditional models that assume rationality.

A recent study on differentially private policy optimization (DPPO) has been published, focusing on the sample complexity of policy optimization (PO) in reinforcement learning (RL). This research addresses privacy concerns in sensitive applications such as robotics and healthcare by formalizing a definition of differential privacy tailored to PO and analyzing the sample complexity of various PO algorithms under DP constraints.
