Longitudinal EHR data is characterized by events occurring in temporal clusters and being highly correlated with one another, and the strict sequential generation assumption of AR models does not fully align with this characteristic.

UnverifiedThe core assumption of time series modeling is that data points are arranged in time order and that adjacent observations are correlated.68% similarUnverifiedThis study models the data selection problem as a high-dimensional regression scenario with multiple heterogeneous data sources, and employs a weighted ridge regression estimator to fuse these sources.64% similarUnverifiedCurrent generative models are essentially limited to the association level—identifying statistical co-occurrence patterns in data—and lack causal reasoning capability.63% similarUnverifiedWhen multiple models show anomalies at the same time, it is more likely that the routing, scheduling, authentication, or rate-limiting components they share experienced fluctuations, rather than that a single model's weights or inference logic failed individually.63% similarUnverifiedDiscrete flow matching can modify the entire sequence in parallel and theoretically has higher parallelism than autoregressive models, but requires multiple full forward passes.62% similar
