The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI-TT) project is to create a system that analyzes and generates sequences of symbols. Symbolic systems transmit information in a variety of applications, such as DNA sequences, synthetic biology, and combinatorial chemistry. It also forms the backbone of music, which can be viewed as highly context-dependent sequence of symbols where each note or event foreshadows those yet to come. The proposed technology offers new ways of engaging with music, for both music streaming service listeners and musicians (comprising 26% of the US population) alike. This technology will address the music industry and for many additional applications. The proposed project exploits nonlinear chaotic system variability to generate variations of context-dependent symbol sequences, such as those comprising musical works. While many applications require methods to eliminate chaotic behavior, a dissipative system operating in its `chaotic regime’ can be viewed as offering a natural mechanism for variability, due to the sensitivity of its solutions to initial conditions. This built-in variability can be exploited by a chaotic mapping technique that transforms an ordered input into a variant-ordered output with potential outcomes ranging from high similarity to the original work to significant mutation. The method includes parsing the input into an ordered sequence of original elements {Ni}, which are sequentially indexed by successive integer values i=1,…, Imax. For each i, a selection algorithm determines whether Ni is a candidate for modification or replacement, thus becoming a “receptor element.” A substitution or modifying algorithm then operates on at least one of the receptor elements by varying or replacing it with a substitution element. The resulting ordered set of original and substituted or modified elements comprises the variant output.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该创新合作伙伴关系 - 技术翻译 (PFI-TT) 项目的更广泛影响/商业潜力是创建一个可以嵌入和生成符号序列的系统，符号系统在各种应用中传输信息，例如 DNA 序列、合成生物学。它也构成了音乐的支柱，可以被视为高度依赖于上下文的符号序列，其中每个音符或事件都预示着即将到来的音乐。流媒体服务该技术将针对音乐行业和许多其他应用，利用非线性混沌系统可变性来生成依赖于上下文的符号序列的变化，例如包含音乐的符号序列。虽然许多应用需要消除混沌行为的方法，但由于其解决方案对初始条件的敏感性，在“混沌状态”下运行的耗散系统可以被视为提供了一种自然的可变性机制。被混沌映射利用将有序输入转换为变体有序输出的技术，其潜在结果范围从与原始作品的高度相似性到显着突变。该方法包括将输入解析为原始元素 {Ni} 的有序序列，这些序列按连续索引。整数值 i=1,…, Imax。对于每个 i，选择算法确定 Ni 是否是修改或替换的候选者，从而成为“受体元素”。然后，替换或修改算法对以下至少一个进行操作受体元件通过改变或用替换元素替换它。由此产生的原始元素和替换或修改元素的有序集包括变体输出。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
