Predictive Information in Discrete-time Gaussian Processes
Description | We proposed a new information-theoretic measure of the complexity between random variables, called "binding information", which is sensitive to the presence of higher-order interactions. We related this to other information-theoretic measures such as entropy, predictive information and erasure entropy. For binary random variables, binding information is maximized by a parity process. We also extended our previous work on symbolic predictive information rate (PIR) to real-valued signals such as autoregressive Gaussian processes AR(N) and moving average processes MA(N). We showed that PIR is unbounded for MA(N) processes. Applying this to analysis of musical audio (Steve Reich: Drumming), we found that Bayesian surprise and predictive information rate correspond to significant events in the score and structural features of the music. We introduced a music composition tool based on searching a space with varying predictive information rate, formed as a trade-off between periodicity, repetition and noise. This tool, the "Melody triangle", was implemented firstly within a room using a Kinect motion sensor, and subsequently as an Android smartphone app. The Melody triangle allows people to indicate which melodies they "like", allowing us to survey user preferences and compare against our information measures. |
Exploitation Route | In music, the measures of information applied to music could give music composers and listeners new insights into the structure of music that they work with. It could also lead to accessible adaptive composition tools allowing users to select the complexity of music they prefer. By matching preference to musical experience of listeners, it could also be used as part of music recommendation systems. Other potential applications include improved prediction models for music coding and compression. |
