EM-based iterations for multiple instance learning on a query-value model
Ethan Levien
In multiple instance regression (MIR) data are organized into bags (collections of instances in feature space) and the goal is to learn a mapping that assigns labels to bags. A typ…
Coarse-graining and stochastic oscillations in a phenomenological model of cell-size homeostasis
Ethan Levien, Jessica Rattray
Within a continuous-time, stochastic model of single-cell size homeostasis, we study how the structure of feedback from size to growth rates and cell-cycle progression shapes overa…
Size-structured populations with growth fluctuations: Feynman--Kac formula and decoupling
Ethan Levien, Yaïr Hein, Farshid Jafarpour
We study a size-structured population model in which individual cells grow at a rate determined by a fluctuating internal variable (e.g., gene expression levels). Many previous mod…
Extremal events dictate population growth rate inference
Trevor GrandPre, Ethan Levien, Ariel Amir
Recent methods have been developed to map single-cell lineage statistics to population growth. Because population growth selects for exponentially rare phenotypes, these methods in…
Coalescent processes emerging from large deviations
Ethan Levien
The classical model for the genealogies of a neutrally evolving population in a fixed environment is due to Kingman. Kingman's coalescent process, which produces a binary tree, uni…
Non-genetic variability: survival strategy or nuisance?
Ethan Levien, Jiseon Min, Jane Kondev +1
The observation that phenotypic variability is ubiquitous in isogenic populations has led to a multitude of experimental and theoretical studies seeking to probe the causes and con…
Coupling sample paths to the partial thermodynamic limit in stochastic chemical reaction networks
Ethan Levien, Paul C. Bressloff
Many biochemical systems appearing in applications have a multiscale structure so that they converge to piecewise deterministic Markov processes in a thermodynamic limit. The stati…
