New pretraining method boosts code representation model robustness

Researchers have introduced Invariant Pretraining (InvPT), a novel method to enhance the robustness of encoder-based code representation models. These models, commonly used for tasks like clone detection and code classification, often degrade in performance when faced with semantically equivalent code written in different syntactic forms. InvPT addresses this by employing a code-only continued pretraining strategy that combines masked language modeling with multi-positive supervised contrastive learning. This approach treats all syntactic variations of the same function as positive examples, improving robustness by up to 19 percentage points on specific tasks while maintaining or enhancing standard accuracy.

    Invariant Pretraining for Robust Code Representations

    arXiv:2608.15412v1 Announce Type: cross Abstract: Encoder-based code representation models remain widely deployed for discriminative tasks such as clone detection and code classification, where their small size and low inference cost are decisive. Their robustness, however, is fr…
