基于自注意力机制神经机器翻译的软件缺陷自动修复方法
Self-Attention Neural Machine Translation for Automatic Software Repair
摘要
Abstract
Recurrent neural network has good ability of the processing for code sequences,and the patch generation model is mostly implemented by it.However,recurrent neural network-based patch generation models still have some limi-tations when dealing with long-distance dependencies in code sequences,and their repair success rate and repair efficiency is low.To address the issue,we present SNRepair,an automatic software fault repair based on self-attention neural machine translation.First,the subword tokenization technology is introduced to preprocess the dataset to alleviate the problem of out of vocabulary.Second,a Transformer program patch generation model that integrates local modeling is constructed to alle-viate the long-distance dependencies in the source code and make better use of local information.Third,the automatic fault localization technology is used to locate the possible fault position and the Transformer patch generation model through pa-rameter optimization is adopted to generate candidate patches.Finally,the candidate patches are verified by test cases.On the 395 real Java software faults in the Defects4J,the results show that the SNRepair has higher repair success rate and re-pair efficiency than the compared ones.关键词
