Researchers have introduced Conditional Föllmer Flow, a novel deep generative method based on ordinary differential equations (ODEs) for learning conditional distributions. This method starts with a standard Gaussian distribution and approximates the target conditional distribution effectively. The approach discretizes the flow using Euler's method, with a deep neural network estimating the velocity field. The paper also provides a theoretical convergence analysis for the Wasserstein-2 distance, offering the first comprehensive end-to-end error analysis for this type of conditional distribution learning. Numerical experiments demonstrate its superior performance compared to existing methods across various scenarios, including image data. AI
