Jerk Matters: Teaching Reinforcement Learning Some Mechanical Manners
Opening — Why this matters now Reinforcement learning (RL) has a bad habit: it optimizes rewards with the enthusiasm of a short‑term trader and the restraint of a caffeinated squirrel. In simulation, this is tolerable. In the real world—where motors wear down, compressors hate being toggled, and electricity bills arrive monthly—it is not. As RL inches closer to deployment in robotics, energy systems, and smart infrastructure, one uncomfortable truth keeps resurfacing: reward-optimal policies are often physically hostile. The question is no longer whether RL can control real systems, but whether it can do so without shaking them apart. ...
