FreeBridge: Variational Schr\"odinger Bridges for Cellular Transition Dynamics

arXiv:2606.11286v1 Announce Type: new Abstract: High-content imaging assays quantify cellular responses to chemical and genetic perturbations, yet continuous trajectories of individual cells are unobservable because cells are chemically fixed at acquisition. Perturbation modeling therefore reduces to inferring stochastic transport between control and treated populations observed only as separate marginals. While recent generative models achieve strong end-point alignment, boundary consistency does not determine intermediate evolution: multiple stochastic processes may connect identical margina

Why this matters
Why now

The proliferation of high-content imaging assays in biological research is driving demand for advanced computational methods to infer complex cellular dynamics from static observations.

Why it’s important

This research addresses a fundamental limitation in analyzing cellular responses by enabling the inference of continuous cellular trajectories, which are crucial for understanding disease progression and drug efficacy.

What changes

The ability to accurately model intermediate cellular evolution from separate marginal observations significantly enhances the power of perturbation modeling in biological research.
