Variational Bayesian Linear Dynamical Systems 5.1 Introduction This chapter is concerned with the variational Bayesian treatment of Linear Dynamical Systems (LDSs), also known as linear-Gaussian state-space models (SSMs). These models are widely used in the fields of signal filtering, prediction and control, because: (1) many systems of inter-

Generally speaking, variational message passing is more amenable to semiparametric re-gression than expectation propagation. It is a special case of mean field variational Bayes (e.g.

work based on a group-sparse Gaussian scale mixture model. A hierarchical Bayesian estimation is derived using a combination of variational Bayesian inference and a subband-adaptive majorization-minimization method that simpli es computation of the posterior distribution. We show that both of these iterative methods can converge together .

into an additive one by taking logarithms and introduced Bayesian type variational model[14].Steidl and Teuber [14, 25] presented a variational model consisting of the 1-divergence as data fitting term and the TV-semi-norm as regularizer. A variational model involving curve let coefficients for cleaning multiplicative Gamma noise was

this gap by deriving a Bayesian formulation of the anti-sparse coding problem (2) considered in [31]. Note that this objective differs from the contribution in [34] where a Bayesian estima-tor associated with an ' 1-norm loss function has been intro-duced. Instead, we merely introduce a Bayesian counterpart of the variational problem (2).

Stochastic Variational Inference. We develop a scal-able inference method for our model based on stochas-tic variational inference (SVI) (Hoffman et al., 2013), which combines variational inference with stochastic gra-dient estimation. Two key ingredients of our infer
