Researchers have developed a method to reduce the energy consumption of training robot policies by offloading parts of the computation to a Neural Processing Unit (NPU). This approach involves freezing the visual encoder and running its forward pass on an NPU while the action generation module is trained on a GPU. While this method decreased energy usage by up to 27.9% and reduced GPU memory allocation, it also increased training time by as much as 37.7% and slightly lowered the policy success rate compared to a GPU-only baseline.
