Sebastian Persson

PhD student in systems biology at @goteborgsuni working with single-cell modelling

[Kurt Schmoller @SchmollerLab]

To grow a bud, yeast needs to polarize and form a septin ring. But how is the ring diameter controlled and why is it linked to #cellsize? @sPersson96 @CvijovicLab @frank_pado @robert_ife

Seminar on "Scalable Bayesian Inference for Dynamic State-Space Mixed-Effects Models", with Sebastian Persson at 14.00 (Swedish time) on 30 November. Zoom link in the pic below or visit us in room MVL15. @sPersson96

[Sebastian Persson @sPersson96]

To achieve efficient inference, we slightly perturb the underlying model which speeds up inference by a factor of 35. Furthermore, we benchmarked adaptive MCMC-proposals for the pseudo-marginal steps, and our results showed that the robust AM (RAM) sampler performed best. (5/5)

[Sebastian Persson @sPersson96]

Want to use modelling to deduce cellular dynamics and sources of cell heterogeneity?

Read our @uPicchini @cannemara @samuel_wiqvist @CvijovicLab preprint about PEPSDI, a mixed-effects inference engine for stochastic dynamic single-cell models. (1/5)
https://t.co/jHH7K7PTvh

[Sebastian Persson @sPersson96]

More formally, PEPSDI is a Gibbs-sampler performing Bayesian inference for dynamic state-space mixed-effects models. The tractable Gibbs-steps are sampled using HMC, while the intractable steps are sampled using pseudo-marginal approach with (correlated) particle filters. (4/5)
