Researchers have developed a method for automatically grading introductory C++ programming assignments using a fine-tuned BART transformer model. This approach incorporates rubric-based criteria and multitask learning to better mimic human instructor grading behavior. Experiments demonstrated that this rubric-guided training, particularly with boundary-based soft labels, achieved lower error rates and improved grade distribution alignment compared to standard methods.
