arXiv:2605.25439v1 Announce Type: new Abstract: Missing data frequently arises across diverse domains, including time-series and image domains. In the real world, missing occurrences often depend on the unobservable values themselves, which are referred to as Missing Not at Random (MNAR). In this work, we introduce the Missing Pattern Recognized Diffusion Imputation Model (PRDIM), a novel framework that explicitly captures the missing pattern and precisely imputes unobserved values. PRDIM iteratively maximizes the likelihood of the joint distribution for observed values and missing mask under
The proliferation of complex datasets with inherent missing-not-at-random patterns necessitates more sophisticated imputation methods, driving ongoing AI research in this area.
Improved missing data imputation, especially for MNAR scenarios, enhances the reliability and trustworthiness of AI models across critical applications, from medical diagnostics to finance.
The development of models like PRDIM offers more accurate ways to handle challenging missing data patterns, leading to more robust data analysis and predictive performance in AI systems.
