FreeBridge: Variational Schr\"odinger Bridges for Cellular Transition Dynamics
Researchers have developed FreeBridge, a new method for modeling cellular transitions using variational Schrödinger Bridges. This approach infers stochastic processes between control and treated cell populations, even when only marginal endpoint data is available. FreeBridge constrains these learned transitions within the geometry of observed cellular morphologies, improving biological interpretability and reducing violations of intermediate support. The method demonstrates competitive or improved performance on several benchmark datasets, including BBBC021, RxRx1, and JUMP. AI
