A Nonlinear Approach to Generate Creative Data using Physarum polycephalum-based Memristors
MetadataShow full item record
This chapter presents a generic biocomputing system developed to generate data for creative pieces such as music and art. It harnesses the nonlinear behaviour of Physarum polycephalum-based memristors, which is in contrast to stochastic processes that are often explored in creative systems. Within this chapter, we explain the advantages of using biomemristors for such applications and discuss a compact and portable biocomputer called PhyBox. It harnesses biomemristors as processing units and highlights the need for non-digital ways of representing, processing, and storing data. The system generates new creative pieces that are inspired by seed data that is input by the user. It allows the user to determine the degree of similarity between the output and the pre-existing creative data by controlling the nonlinearity of Physarum polycephalum-based memristors. The mapping procedure considers the resistor's behaviour to be ideal and reproduces the pre-existing data if a resistor is connected instead of a memristor. Our system is generic because it does not depend on the type of creative piece that is being processed. The chapter presents results from testing the system under dif erent scenarios and provides ways for creative practitioners to adopt Unconventional Computing technologies in their works.
