Test Datasets
This dataset comprises vital signs, lab tests, administered fluid boluses and vasopressors for 3,910 patients with acute hypotension in the intensive care unit.
What you should know about this dataset
These synthetic data were generated based on the MIMIC-III Clinical Database. The cohort was defined according to [1]Gottesman O, Futoma J, Liu Y, Parbhoo S, Celi L, Brunskill E, Doshi-Velez F. Interpretable Off-Policy Evaluation in Reinforcement Learning by Highlighting Influential Transitions. Proceedings of the … Continue reading, and included adults with an initial ICU stay of at least 24 hours and seven or more mean arterial pressure (MAP) values of 65mmHg or less, indicating probable acute hypotension. All synthetic records have a length of 48 hours.

Correlation
Comparison of correlations
The matrices below show:
1) Static correlations between pairs of variables for all patients at any time, in the real and synthetic data.
2) Dynamic correlations between variables in the real and synthetic data. Time series for each patient were linearly decomposed into trends (indicating a general upward or downward slope) and cycles (indicating periodic patterns). Correlations were then computed between trends and cycles for all patients.
