For this challenge, participants are provided with three data sets of 100 records each. Each ten-minute record contains 6, 7, or 8 signals acquired from bedside ICU patient monitors. The recorded signals vary across records, and they include ECG, continuous invasive blood pressure, respiration, fingertip plethysmograms, and occasional other signals. In one of these signals, the final 30-second segment (the target signal) has been replaced by a gap (a flat line signal), and the goal is to reconstruct this missing 30-second target signal in each record.
- Set A is a set of 100 records for participants' use as a training set. Participants can obtain scores for Set A reconstructions at any time, but Set A scores are not included in the final rankings of Challenge entries. The target signals are provided for the records in this set. Additional training data can easily be constructed from any of the multiparameter data available in PhysioBank, such as the MIMIC II Waveform Database.
- Set B is a set of 100 records for which the target signals are withheld until the conclusion of the challenge. Participants can obtain scores for Set B reconstructions at any time, but Set B scores are not included in the final rankings of Challenge entries.
- Set C is a set of 100 records, with the target signals withheld. Participants may submit reconstructions of the target signals at any time for the duration of the challenge, but they will not receive scores except for their final submissions, which will determine the final rankings and the winners of the challenge.
Records in all three Challenge data sets are provided in standard PhysioBank (compact binary) formats; read them using the WFDB software package, use the PhysioBank ATM to convert them to text, CSV, Matlab, or EDF formats, or see How to obtain PhysioBank data in text form for notes on other methods for converting them to text. The Set A files named with the suffix .missing are the target signals; these files are in text format.
The data sets, together with the target signals for Set A, are available via links in the directory listing below. To download them efficiently, use rsync as described here (retrieve the challenge-2010 "module"). For convenience, a tarball containing the full contents of all three data sets is also provided.
