多層網絡因其能夠很好地描述現實世界中的各種關係而廣受關注，而雙層網絡是多層網絡的特殊形式。本研究的目的在於引入一種新的基於熵的針對多層網絡，特別是雙層網絡的測度。這種新的測度指標基於資訊論中的關鍵概念——資訊熵，稱作交互作用熵，可應用於各種類型的多層網絡以量化其中雙層之間的差異。

The multiplex network has attracted wide attention because it can better describe the various relationships in the real world, and the duplex network is a special two-layer form of it. The purpose of this research focuses on introducing new entropy-based measures for multiplex network, especially duplex network. The new measure called Interactive entropy in duplex network (IE) is based on information entropy, a key concept of information theory. It can be applied to various types of multiplex networks to quantify the differences between the layers of inside duplex network.
