Autoregressive models for biomedical signal processing. (arXiv:2304.11070v1 [eess.SP])
cs.LG updates on arXiv.org arxiv.org
Autoregressive models are ubiquitous tools for the analysis of time series in
many domains such as computational neuroscience and biomedical engineering. In
these domains, data is, for example, collected from measurements of brain
activity. Crucially, this data is subject to measurement errors as well as
uncertainties in the underlying system model. As a result, standard signal
processing using autoregressive model estimators may be biased. We present a
framework for autoregressive modelling that incorporates these uncertainties
explicitly via an overparameterised loss …
