Researchers have developed ReCoGen, a novel two-stage framework designed to generate continuous physiological time-series data, particularly when faced with missing or irregularly sampled information. The first stage involves training modality-specific masked autoencoders to distill various data types into compact, missingness-tolerant token sequences. The second stage utilizes a flow-matching generator that fuses these tokens with static conditions to synthesize the target signal. ReCoGen demonstrated superior performance across multiple benchmarks, including datasets like MIMIC-III and MIMIC-IV, outperforming existing conditional generators and achieving utility comparable to real-world data.
