Researchers have developed MILM, a large language model designed to process multimodal irregular time series data. This model represents time-series data as XML triplets and employs a two-stage fine-tuning strategy. The first stage focuses on learning from sampling patterns alone, while the second stage integrates observed values for joint modeling. MILM has demonstrated strong performance on electronic health record datasets, particularly in predicting in-hospital mortality, outperforming a single-stage model in scenarios with missing values.
