Boyang Yang, Liuye Guo, Tao Zheng, Tieke He, Yidong Wan, You Lv, Zhipeng Wang, Zhuowei Wang

Cross-lingual transfer from C++ raises low-resource language repair Pass@1 from 1.67% to 11.97% on CodeLlama.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Using C++ as the source HRPL and Ruby and Rust as the target LRPLs, experiments on xCodeEval show that HELO-APR consistently outperforms strong baselines, increasing Pass@1 from 31.32% to 48.65% on DeepSeek-Coder-6.7B and from 1.67% to 11.97% on CodeLlama-7B, while improving syntactic validity by raising the average target compilation rate on CodeLlama from 49.77% to 91.98%.

C2weakest assumption

The assumption that synthesizing LRPL buggy-fixed pairs from HRPL counterparts can preserve defect type consistency while ensuring the synthesized code is idiomatic, which is required for the data construction stage to provide effective supervision.

C3one line summary

HELO-APR improves LLM-based automatic program repair in low-resource languages by synthesizing cross-lingual training data and using curriculum learning, raising Pass@1 from 31.32% to 48.65% on DeepSeek-Coder for Ruby/Rust targets.
