Researchers have introduced a novel geometric perspective on reward function updates within Inverse Reinforcement Learning (IRL). This approach shifts focus from traditional gradient-based optimization to the geometry of occupancy space. By leveraging insights into the optimal solution and its geometric properties, the study demonstrates how the geometry along the e-geodesic influences the gradient of the IRL dual problem. This leads to a preconditioned gradient that offers efficient, natural-gradient-style updates with minimal computational overhead, and also connects policy search to approximate entropic Mirror Descent.
