A data-driven identification of dynamical systems
requiring only minimal prior knowledge
is promising whenever no analytically derived
model structure is available, e.g., from first principles
in physics. However, meta-knowledge on
the system’s behavior is often given and should
be exploited: Stability as fundamental property
is essential when the model is used for controller
design or movement generation. Therefore, this
paper proposes a framework for learning stable
stochastic systems from data. We focus on
identifying a state-dependent coefficient form of
the nonlinear stochastic model which is globally
asymptotically stable according to probabilistic
Lyapunov methods. We compare our approach
to other state of the art methods on real-world
datasets in terms of flexibility and stability.
