From reading the code, it seems that the GRPO advantage computation effectively degenerates to using raw rewards. Since a randomly generated UUID is assigned to each sample as the grouping key, every ...
Abstract: For the detection of buried targets in a dielectric medium, the decomposition of time-reversal operator (DORT) using a multistatic system has been effective in separating multiple targets ...
Abstract: Personal data have been increasingly used in data-driven applications to improve quality of life. However, privacy preservation of personal data while sharing it with analysts/ researchers ...
