“…A Gaussian Process prior (GP prior, (Stein, 2012)) is used to infer the non-parametric terms. Gaussian processes are highly flexible and have been used extensively in other molecular biology applications, such as gene-expression time courses (Kirk and Stumpf, 2009; Kirk et al ., 2012; Stegle et al ., 2010; Cooke et al ., 2011; Babtie et al ., 2014), single-cell transcriptomics (Reid and Wernisch, 2016; Boukouvalas et al ., 2018; Strauss et al ., 2020) and spatial proteomics (Crook et al ., 2019; Shin et al ., 2019).…”
