We present here a hierarchical model for the evolution of compositional language. The model has the structure of a two-sender/one-receiver Lewis signaling game augmented with executive agents who may learn to influence the behavior of the basic senders and receiver. The model shows how functional agents might coevolve representational roles even as they evolve a reliable compositional language in the context of costly signaling. When successful, the evolved language captures both the compositional structure of properties in the world and the compositional structure of successful actions involving those properties.

论组合语言的演变

我们在这里提出了一个用于组合语言演变的分层模型。该模型具有两个发送者/一个接收者刘易斯信号游戏的结构，增强了执行代理，他们可以学习影响基本发送者和接收者的行为。该模型显示了功能代理如何共同进化表征角色，即使它们在代价高昂的信号环境中进化出可靠的组合语言。当成功时，进化语言既捕获了世界中属性的组成结构，也捕获了涉及这些属性的成功动作的组成结构。
