Self-Adaptive Code Representation: Grammar-Guided or Token-Based?

Recent advances in code intelligence are largely driven by large language models (LLMs), which represent code as token sequences and achieve strong results on many software engineering tasks. However, standard token-based approaches often struggle to capture the inherent structural regularities of programming languages...
