摘要:

人在回路机器学习被广泛用于人工智能(AI)中,以从专家那里获取数据点的标签,或者提供关于预测结果与目标有多接近的反馈。这简化了专家决策过程的所有细节。在这项工作中,我们允许专家额外产生决策规则描述他们的决策,规则预计是不完美的,但提供额外的信息。特别地,规则可以扩展到新的分布,并且因此能够显著地提高训练和测试分布不同的情况下的性能,例如在领域自适应中。我们将所提出的方法应用于终身学习和领域自适应问题,并讨论在人工智能的其他分支,如专家系统中的知识获取问题的应用。在模拟和真实用户的研究中,我们表明,决策规则的启发提高了领域自适应的算法,并有助于传播专家的知识的AI模型。

英文摘要:

Human-in-the-loop machine learning is widely used in artificial intelligence (AI) to elicit labels for data points from experts or to provide feedback on how close the predicted results are to the target. This simplifies away all the details of the decision-making process of the expert. In this work, we allow the experts to additionally produce decision rules describing their decision-making; the rules are expected to be imperfect but to give additional information. In particular, the rules can extend to new distributions, and hence enable significantly improving performance for cases where the training and testing distributions differ, such as in domain adaptation. We apply the proposed method to lifelong learning and domain adaptation problems and discuss applications in other branches of AI, such as knowledge acquisition problems in expert systems. In simulated and real-user studies, we show that decision rule elicitation improves domain adaptation of the algorithm and helps to propagate expert's knowledge to the AI model.
