Researchers visualize critic match loss landscapes for RL control algorithms

Researchers have developed a new method to visualize the loss landscapes of critic neural networks in online reinforcement learning algorithms. This technique projects parameter trajectories onto a low-dimensional subspace, creating a 3D loss surface and a 2D optimization path to characterize critic learning behavior. The approach, demonstrated on cart-pole and spacecraft control tasks, introduces quantitative indices to compare training outcomes and distinguish between stable convergence and unstable learning.
