2019 News


MIMIC-III available on the cloud

News from: MIMIC-III Clinical Database v1.4.

Sept. 30, 2019

The MIMIC-III database is now available on two major cloud platforms: Google Cloud Platform (GCP) and Amazon Web Services (AWS). To access the data on the cloud, simply add the relevant cloud identifier to your PhysioNet profile. Further instructions are available on the MIMIC-III website.

Tutorials are available for using MIMIC-III with BigQuery (GCP) and using MIMIC-III with Athena (AWS).

MIMIC-CXR Database v2.0.0 now available!

News from: MIMIC-CXR Database v2.0.0.

Sept. 27, 2019

The MIMIC-CXR Database has been updated to v2.0.0. The database now contains DICOM format image files and free-text radiology reports. All data has been de-identified.

Credentialed users can access the data after signing the data use agreement.

Some users may have preferred the JPG format images for convenience, despite the information loss when storing the images in this format. We plan to release a distinct project on PhysioNet which contains the same images as MIMIC-CXR but in JPG format. This distinct project will also contain structured labels derived from the radiology report. Stay tuned!

May 28, 2019

  • We are accepting requests for Google Cloud Credits ($500 per eligible team). Requests are due by 29 May, 2019. Please see here for more information on how to apply for them. Requests will be processed in order and sent on to Google. We cannot guarantee you will receive them, especially later in the competition.

Notices of acceptance have been sent for CinC abstracts

May 24, 2019

  • By now you should have received your acceptance or rejection notices for your abstracts. If you were rejected, please do not worry - there are two more options to compete. See here and here for more information on this.
  • We have added a `wild card' entry to allow one more team to enter the competition and be eligible for all the prizes. See here for more information on this.
  • There will be an on-site hackathon revisiting the Challenge (with a separate award) on Sunday 8th September, before the conference begins in Singapore. Any team (whether previously registered for the Challenge or not) with at least one attendee at the conference, who turns up in person to register for the Hackathon, is eligible to enter. See here for more information on this.

Now accepting Challenge submissions

News from: Early Prediction of Sepsis from Clinical Data -- the PhysioNet Computing in Cardiology Challenge 2019 v1.0.0.

April 25, 2019

  • We are now accepting submissions for the official phase of the Challenge.
  • Please check the submission instructions for information about how to submit your entry and a FAQ with common submission issues.
  • When ready, please submit your entry here.

Official phase of the 20th PhysioNet/Computing in Cardiology Challenge is now open.

News from: Early Prediction of Sepsis from Clinical Data -- the PhysioNet Computing in Cardiology Challenge 2019 v1.0.0.

April 22, 2019

  • We have made several changes from the unofficial phase of the Challenge (see below). We invite comments and questions about these changes. We plan to accept submissions again on Thursday, 25 April at 12:01 am GMT.
  • We will only use our new cloud submission system for the official phase of the Challenge. See the updated instructions (here) for details. The past submission system is no longer available.
  • We ask participants to write causal algorithms that make predictions using current and past (but not future) information. See the submission instructions and sample prediction code (here) for details.
  • Note that you will have 10 submissions in this official phase. We will score your results on a subset of the test data. At the end of the competition we will ask you to nominate your 'best' algorithm (it need not be the one that gave you the best score) and we will run it on the full test data to provide the final test score.
  • Please do not submit all ten entries in the last week of the competition. Even though we can scale the computing, failures require manual intervention and feedback. We can't do this for 1000+ entries in the final week.
  • Also - we will be offering up to $500 in Google Cloud credits (courtesy of the Google Cloud Team) to the best performing entries by June, so it's worth getting a good score before then!

Cloud submission system for the 2019 PhysioNet Challenge

News from: Early Prediction of Sepsis from Clinical Data -- the PhysioNet Computing in Cardiology Challenge 2019 v1.0.0.

April 11, 2019

  • We have now implemented a cloud submission system. Instructions for the cloud submission system available here.
  • The deadline of the unofficial phase of the competition has been extended to 11.59pm GMT on Sunday 14th April 2019. This will give you enough time to receive scores and, very importantly, submit abstracts to cinc.org before the 15th. Please see here for important hints on how to prepare a successful abstract, even if you don't receive a score.
  • If you don't receive a score - don't panic - just submit an abstract to cinc.org by the deadline on the 15th April with some results - cross validated on the training data.
  • The hiatus has now been moved, and starts on the 15th April and lasts until 12 midnight GMT on the 21st April. The Challenge re-opens at 12.01 am GMT on the 22 April.

GMSE is a new computational tool for quantifying the volatility of time series. This work extends the multiscale entropy (MSE) algorithm currently available on PhysioNet. The GMSE method was first described in Costa M., Goldberger A.L. Generalized Multiscale Entropy Analysis: Application to Quantifying the Complex Volatility of Human Heartbeat Time Series. Entropy 2015;17:1197-1203.
