_DESCRIPTION = """\ |
|
Dataset for mimic4 data, by default for the Mortality task. |
|
Available tasks are: Mortality, Length of Stay, Readmission, Phenotype, Mortality Custom, Length of Stay Custom, Readmission Custom, Phenotype Custom. |
|
The data is extracted from the mimic4 database using this pipeline: 'https://github.com/healthylaife/MIMIC-IV-Data-Pipeline/tree/main' |
|
mimic path should have this form : "path/to/mimic4data/from/username/mimiciv/2.2" |
|
If you choose a Custom task provide a configuration file for the Time series. |
