GENOT: Entropic (Gromov) Wasserstein Flow Matching with Applications to Single-Cell Genomics

Single-cell genomics has significantly advanced our understanding of cellular behavior, catalyzing innovations in treatments and precision medicine. However,single-cell sequencing technologies are inherently destructive and can only measure a limited array of data modalities simultaneously. Optimal transport (OT)has emerged as a potent solution, but traditional discrete solvers are hampered byscalability, privacy, and out-of-sample estimation issues. These challenges havespurred the development of neural network-based solvers, known as neural OTsolvers, that parameterize OT maps. Yet, these models often lack the flexibilityneeded for broader life science applications.
