Week 4 - 220B
Modeling Creativity - Winter Quarter, 1999
The task in week 4 is to learn how to use the Planet neural network simulator by examples.
To read and experiment with the code in aim to excute the examples download the files
located in: /amd/cm/usr/local/web/CCRMA/Courses/220b/week4.
Some major steps and graphics in working on such a model
Buiding a model of context formulation and resulting expectations created by a listener while
attending to tonal music. The model uses modular subnetworks to simulate the distinct yet
mutually influential schemas involved in constructing expectations for sequential events
and the temporal cyclical grid that creates metrical support for these expectations.
The model visualizes the fluctuations of musical expectations that arise as a consequence of
the dynamically changing musical context.
The corpus contains 15 sequences of dupled meter chord progression and more 15 for
Architeture and Representation
In the learning phase the net learns to reproduce the 30 examples, the error graph gives
indication for the quality of the learning process as a function of 1500 learning steps.
