abstract = {In recent years, the development of cheap and robust
sensors combined with the ever increasing availability of
the internet led to a revolution in information technology,
giving rise to an amount of data, which was unimaginable
just a decade ago. This explosion in data lead to an
increased demand for algorithms for processing this data.
However, an often overlooked aspect is that with ever
sophisticated algorithms there is associated a demand for
equally sophisticated mathematical modelling. In this
thesis, we explore the interaction between algorithm design
and modelling. Although, the models and methods discussed
here are not limited to any single domain of application, we
will base our discussion on example applications from the
domain of biomedical engineering. This is because the
analysis of physiological time series is characterised by
two problems which help to highlightthe importance of
modelling. First, the high noise level of biological signals
requires strong regularization, which can be provided via a
model. Second, in many medical applications the value of
interest is not directly observable. Thus, these latent
variables have to be estimated, e.g. with the help of a
model. In the course of our discussion, we will encounter
two major modalities. The first one is Ballistocardiography
(BCG), a modality often used in home monitoring
applications, which is based on simple pressure sensors,
yielding a scalar signal. The second modality is functional
magnetic resonance imaging (fMRI), a complex and highly
sophisticated method, capable of generating images of brain
functionality. [...]},
