Our 2024 paper showed that policy gradient RL (with performance-based memory updates) predicts long-horizon motor learning. Now,
@adrianhaith.bsky.social shows that policy-gradient RL also explains learning in other shorter horizon tasks. Exciting!

Policy-Gradient Reinforcement Learning as a General Theory of Practice-Based Motor Skill Learning
Mastering any new skill requires extensive practice, but the computational principles underlying this learning are not clearly understood. Existing theories of motor learning can explain short-term ad...
