CT-OT Flow: Estimating Continuous-Time Dynamics from Discrete Temporal Snapshots
Researchers have developed a new framework called CT-OT Flow to estimate continuous-time dynamics from discrete, aggregated data snapshots. This method addresses challenges like noisy timestamps and the absence of continuous trajectories by inferring precise time labels and reconstructing distributions through temporal kernel smoothing. CT-OT Flow has demonstrated improved performance over existing methods on synthetic and real-world datasets, including scRNA-seq and typhoon track data. AI
