AI总结:

研究人工生命系统中Gifbreeder的肢体形态,通过用户审美选择进化时空场产生类似生物的形态,用输入空间扰动评估其行为,探讨其反应是否反映目标导向行为及类似智能体动力学如何在无明确规则系统中出现。

AI中文摘要:

人工生命系统通常由一组作用于环境、智能体或两者的动力学规则定义,从中可能出现逼真的模式。Gifbreeder是交互式进化计算(IEC)平台Picbreeder的动画版本,最初用于生成视觉艺术。Gifbreeder基因组不编码智能体或环境,而是编码一个时空场,并通过用户的审美选择进行进化。进化后的表达有时类似于能动的逼真生物,即肢体形态,因为它们存在于确定性的三秒循环“边缘状态”。我们通过输入空间扰动评估它们的行为,发现了对不同类型扰动的物种特异性反应。我们讨论这些反应是否可能反映了如导航般的目标导向行为,或仅仅是其表象,更广泛地探讨了在没有明确界定智能体、环境或交互规则的系统中,类似智能体的动力学是如何出现的。

英文摘要:

Artificial life systems are typically defined by a set of dynamical rules over an environment, an agent, or both, from which lifelike patterns may emerge. Gifbreeder is an animated version of the interactive evolutionary computation (IEC) platform Picbreeder, and was initially created to generate visual art. Instead of encoding the agent or the environment, Gifbreeder genomes encode a spatiotemporal field and evolve through the user's aesthetic selection. The evolved expressions can sometimes resemble motile lifelike creatures that we term Limbomorphs, given that they exist in a deterministic three-second looping "limbo". We assess their behavior via input-space perturbations and find species-specific reactions to different kinds of perturbations. We discuss whether these reactions may reflect goal-directed behavior like navigation, or merely the appearance of it, and more broadly how agent-like dynamics may emerge in a system with no explicitly defined agent, environment, or interaction rules.
