Enhancing the Performance of Neural Networks Through Causal Discovery and Integration of Domain Knowledge
通过因果发现与领域知识整合提升神经网络预测表现
In this paper, we develop a generic methodology to encode hierarchical causality structure among observed variables into a neural network in order to improve its predictive performance. The proposed methodology, called causality-informed neural network (CINN), leverages three coherent steps to systematically map the structural causal knowledge into the layer-to-layer design of neural network while strictly preserving the orientation of every causal relationship. In the first…
