Systematic model reduction captures the dynamics of extrinsic noise in biochemical subnetworks
Barbara Bravi, Katy J. Rubin, Peter Sollich
We consider the general problem of describing the dynamics of subnetworks of larger biochemical reaction networks, e.g. protein interaction networks involving complex formation and…
Critical scaling in hidden state inference for linear Langevin dynamics
Barbara Bravi, Peter Sollich
We consider the problem of inferring the dynamics of unknown (i.e. hidden) nodes from a set of observed trajectories and study analytically the average prediction error and the typ…
Statistical physics approaches to subnetwork dynamics in biochemical systems
Barbara Bravi, Peter Sollich
We apply a Gaussian variational approximation to model reduction in large biochemical networks of unary and binary reactions. We focus on a small subset of variables (subnetwork) o…
Inferring hidden states in Langevin dynamics on large networks: Average case performance
Barbara Bravi, Manfred Opper, Peter Sollich
We present average performance results for dynamical inference problems in large networks, where a set of nodes is hidden while the time trajectories of the others are observed. Ex…
Inference for dynamics of continuous variables: the Extended Plefka Expansion with hidden nodes
Barbara Bravi, Peter Sollich
We consider the problem of a subnetwork of observed nodes embedded into a larger bulk of unknown (i.e. hidden) nodes, where the aim is to infer these hidden states given informatio…
Extended Plefka Expansion for Stochastic Dynamics
Barbara Bravi, Peter Sollich, Manfred Opper
We propose an extension of the Plefka expansion, which is well known for the dynamics of discrete spins, to stochastic differential equations with continuous degrees of freedom and…
