论文摘要

尽管近年来AI在解决高度复杂问题方面取得了成功,但邦加德问题(BPS)的成功,但现代ML技术仍无法解决。在本文中,我们提出了一种新方法,不仅试图解决BP,还可以从学习的表示中提取意义。这包括将经典BP重新制定为增强学习(RL)设置,这将使模型能够访问反事实来指导其决策,同时也解释其决策。由于在BPS中学习有意义的表示是必不可少的子问题,因此我们进一步利用对比度学习来从像素数据中提取低级别的特征。已经进行了几项实验,用于分析一般的BP-RL设置,特征提取方法,并使用最佳组合来进行特征空间分析及其解释。

Even though AI has advanced rapidly in recent years displaying success in solving highly complex problems, the class of Bongard Problems (BPs) yet remain largely unsolved by modern ML techniques. In this paper, we propose a new approach in an attempt to not only solve BPs but also extract meaning out of learned representations. This includes the reformulation of the classical BP into a reinforcement learning (RL) setting which will allow the model to gain access to counterfactuals to guide its decisions but also explain its decisions. Since learning meaningful representations in BPs is an essential sub-problem, we further make use of contrastive learning for the extraction of low level features from pixel data. Several experiments have been conducted for analyzing the general BP-RL setup, feature extraction methods and using the best combination for the feature space analysis and its interpretation.
