Musicat: a computational model of creativity in a musical domain

这个项目采用了一种新的方法来理解人类的创造力，基于音乐领域创造性思维的认知建模。在过去的三十年里，概念与认知研究中心（CRCC）的流体类比研究小组（FARG）开发的认知模型为解决类比问题、推断数字序列和设计字体等各种创造性任务提供了新的见解。音乐领域为研究认知和创造力的基本机制提供了扩展这些技术的机会。具体来说，该研究旨在开发一种新的音乐认知模型，以模拟音乐中涉及的创作过程。然而，不是在音乐的创作或即兴创作中，而是在看似更简单和更常见的音乐感知行为中。音乐感知如何具有创造性？感知是一个活跃的过程，大脑解释感官输入，并将原始输入转换为压缩格式。这种解释过程远非被动的机器人算法，而是动态的，受认知环境的影响。这种感知不仅是主观的，而且是创造性的，正如它产生的新奇的内部感觉数据表征所证明的那样。这项工作背后的哲学核心原则是，驱动感官输入的创造性感知的过程也会产生高层次的创造性思想、想法和艺术作品。

This project takes a new approach to understanding human creativity, based on cognitive modeling of creative thought in a musical domain. Cognitive models developed by the Fluid Analogies Research Group (FARG) at the Center for Research on Concepts and Cognition (CRCC) in the past three decades have provided new insight into a wide variety of creative tasks such as solving analogy problems, extrapolating number sequences, and designing typefaces. The domain of music provides an opportunity to extend these techniques for the study of fundamental mechanisms of cognition and creativity. Specifically, the proposed research aims to develop a novel model of music cognition that simulates the creative processes involved in music ? not, however, in the composition or improvisation of music, but in the seemingly much simpler and more common act of music perception. How is music perception creative? Perception is an active process where the brain interprets sensory inputs, and transforms the raw input into a compressed format. Far from being a passive, robotic algorithm, this process of interpretation is quite dynamic and influenced by cognitive context. Such perception is not only subjective, but creative, as evidenced by its generation of novel internal representations of sensory data. A central tenet of the philosophy underlying this work is that the exact same processes that drive the creative perception of sensory input also give rise to the high-level generation of creative thoughts, ideas, and works of art.
