摘要:

欧盟的《通用数据保护条例》(GDPR)或美国的《加州消费者隐私法》(CCPA)引入的法规包括关于\textit{right to be forgotten}的规定,要求行业应用程序从其系统中删除与个人相关的数据。在使用机器学习来基于用户数据构建模型的几个现实世界行业应用中,这样的授权要求在数据清理以及模型再训练方面都付出巨大的努力,同时确保模型不会由于数据的移除而在预测质量上恶化。因此,如果这些应用程序以非常高的频率接收此类请求,则连续删除数据和模型重新训练步骤不会扩展。最近,一些研究人员提出了\textit{Machine Unlearning}的想法来应对这一挑战。尽管这一任务非常重要,但在自然语言处理(NLP)任务中,机器遗忘领域还没有得到充分的探索。在本文中,我们探讨了各种GLUE任务\cite{Wang:18},如QQP,SST和MNLI的Unlearning框架。我们提出了计算效率高的方法(SISA-FC和SISA-A)来执行\textit{guaranteed} Unlearning,与基线相比,在保持模型性能不变的同时,在内存(90-95\%),时间(100倍)和空间消耗(99\%)方面都有显着减少。

英文摘要:

Regulations introduced by General Data Protection Regulation (GDPR) in the EU or California Consumer Privacy Act (CCPA) in the US have included provisions on the \textit{right to be forgotten} that mandates industry applications to remove data related to an individual from their systems. In several real world industry applications that use Machine Learning to build models on user data, such mandates require significant effort both in terms of data cleansing as well as model retraining while ensuring the models do not deteriorate in prediction quality due to removal of data. As a result, continuous removal of data and model retraining steps do not scale if these applications receive such requests at a very high frequency. Recently, a few researchers proposed the idea of \textit{Machine Unlearning} to tackle this challenge. Despite the significant importance of this task, the area of Machine Unlearning is under-explored in Natural Language Processing (NLP) tasks. In this paper, we explore the Unlearning framework on various GLUE tasks \cite{Wang:18}, such as, QQP, SST and MNLI. We propose computationally efficient approaches (SISA-FC and SISA-A) to perform \textit{guaranteed} Unlearning that provides significant reduction in terms of both memory (90-95\%), time (100x) and space consumption (99\%) in comparison to the baselines while keeping model performance constant.
