TypeProbe method reveals hidden type representations in code models

Researchers have developed a method called TypeProbe to investigate how pre-trained code models internally represent type information. By analyzing the residual streams of these models using parallel Java and Python datasets, the study found that cross-lingual type representations emerge even in untyped code. The probes can also linearly encode argument and result types, demonstrating a degree of robustness to linguistic and syntactic variations. AI
