Self-Refining Neural Networks: Closed-Loop Debugging with Automated Checker Bug Hypothesis Generation and Repair

Building on the checker bug analysis of Harzevili et al. (2024), which focuses on bugs in library code, this idea takes the concept a step further: can neural networks themselves develop an internal "debugger" that hypothesizes where their own logic or computations might go wrong, particularly during learning or inference on unexpected data? Such a neural debugger could be trained with synthetic bug injection, adversarial attacks, or runtime monitoring, and would not only flag suspicious computations (e.g., anomalous activations or gradients) but also propose repairs—such as re-routing computation paths, modifying network structures, or suggesting data augmentations. This represents a fusion of software engineering and neural architecture, where models become partially self-correcting and resilient to both code- and data-induced failure modes.
