arXiv:2606.17106v1 Announce Type: new Abstract: Laboratory tests in electronic health records are collected irregularly, and the absence of a test order can be as informative as the measurement itself. Such missingness reflects clinicians' decisions and patient physiology, making it important to model it directly rather than treat it as a preprocessing artifact. Here we present a diffusion-based approach for generating clinical time series that jointly models laboratory values and their observation patterns using the public Data Analytics Challenge on Missing Data Imputation (DACMI) benchmark
The proliferation of digital health records and advancements in AI models, particularly diffusion-based approaches, enable more sophisticated analyses of clinical data now.
This development allows for a more accurate and nuanced understanding of patient health by interpreting not just present data, but also the 'why' behind its absence, which is crucial for diagnostic and predictive AI in healthcare.
AI models can now interpret the informational value of missing data in clinical time series, moving beyond treating it as a mere artifact to understanding it as meaningful input.
