Usage

This repository is meant to serve two purposes:

1. To help you download the dataset
2. To allow you to benchmark your model using the official implementation of the metrics

We recommend starting by installing this kits23 package using pip. Once you've done this, you'll be able to use the command-line download entrypoint and call the metrics functions from your own codebase.

Installation

This should be as simple as cloning and installing with pip.

git clone https://github.com/neheller/kits23
cd kits23
pip3 install -e .

We're running Python 3.10.6 on Ubuntu and we suggest that you do too. If you're running a different version of Python 3 and you discover a problem, please submit an issue and we'll try to help. Python 2 or earlier is not supported. If you're running Windows or MacOS, we will do our best to help but we have limited ability to support these environments.

Data Download

Once the kits23 package is installed, you should be able to run the following command from the terminal.

kits23_download_data

This will place the data in the dataset/ folder.

Using the Metrics

We provide a reference implementation for the metrics and the ranking scheme so that participants know exactly how their algorithm is going to be validated. We strongly encourage using these implementations for model selection during development. In order to do this, we recommend training all your models as cross-validations, so that you have predictions for the entire training set with which you can meaningfully evaluate your approaches.

Compute metrics for your predictions

After installing the KiTS23 repository, the following console command is available to you: kits23_compute_metrics. You can use it to evaluate predictions against the training ground truth. It's as simple as

kits23_compute_metrics FOLDER_WITH_PREDICTIONS -num_processes XX

This will produce a evaluation.csv in FOLDER_WITH_PREDICTIONS with the computed Dice and surface Dice scores.

Ranking code

Ranking is based on first averaging your dice and surface dice scores across all cases and HECs, resulting in two values: your average Dice and average Surface Dice. We then use 'rank-then-aggregate' to merge these metrics into a final ranking.

Here are the steps you need to do to run the ranking locally (for example, to find the best configuration for your submission):

1. Execute generate_summary_csv, located in ranking.py. The documentation will tell you how
2. Then use rank_participants from the same file with the summary.csv generated by generate_summary_csv to generate the final ranking.
