Abstract
This paper is concerned with the learning of dynamic
models of compartmental systems visualised as networks
of interconnected tanks. This is intended as an
intermediary step to learn more complex dynamic
biological systems such as metabolic pathways. Our
present aim is to learn systems of differential
equations from time series data to capture physical
models of increasing complexity (u-tube, cascaded
tanks, and coupled tanks). To do so, we use Symbolic
Regression in Genetic Programming and combine it with a
fuzzy representation which has inherent differential
capabilities (Fuzzy Vector Envisionment). We use the
ECJ framework to implement the learner. Present results
show that the system can approximate the target models
and that the use of a weighted fitness function seems
to accelerate the learning process.
