摘要:

随着机器学习(ML)现在广泛应用于许多领域,无论是在研究还是在工业中,对黑盒子内部发生的事情的理解正在成为一个日益增长的需求,特别是对于这些模型的非专家来说。因此,开发了几种方法,以提供对特定观测的模型预测的清晰见解,但代价是计算时间长或限制性假设,没有充分考虑到属性之间的相互作用。本文提供了方法的基础上检测的相关组的属性-命名联盟-影响预测,并与文献进行比较。我们的研究结果表明,这些联盟的方法是更有效的比现有的,如SHapley加法解释(SHAP)。计算时间缩短,同时保持可接受的精度的个人预测解释。因此,这使得解释方法能够更广泛地实际使用,以增加已开发的ML模型、最终用户以及受这些模型所起作用的任何决策影响的人之间的信任。

英文摘要:

As Machine Learning (ML) is now widely applied in many domains, in both research and industry, an understanding of what is happening inside the black box is becoming a growing demand, especially by non-experts of these models. Several approaches had thus been developed to provide clear insights of a model prediction for a particular observation but at the cost of long computation time or restrictive hypothesis that does not fully take into account interaction between attributes. This paper provides methods based on the detection of relevant groups of attributes -- named coalitions -- influencing a prediction and compares them with the literature. Our results show that these coalitional methods are more efficient than existing ones such as SHapley Additive exPlanation (SHAP). Computation time is shortened while preserving an acceptable accuracy of individual prediction explanations. Therefore, this enables wider practical use of explanation methods to increase trust between developed ML models, end-users, and whoever impacted by any decision where these models played a role.
