Today marks the release of scikit-survival 0.21.0. This release features some exciting new features and significant performance improvements:

• Pointwise confidence intervals for the Kaplan-Meier estimator.
• Early stopping in GradientBoostingSurvivalAnalysis.
• Improved performance of fitting SurvivalTree and RandomSurvivalForest.
• Reduced memory footprint of concordance_index_censored.

I’m pleased to announce the release of scikit-survival 0.18.0, which adds support for scikit-learn 1.1.

In addition, this release adds the return_array argument to all models providing predict_survival_function and predict_cumulative_hazard_function. That means you can now choose, whether you want to have the survival (cumulative hazard function) automatically evaluated at the unique event times. This is particular useful for plotting. Previously, you would have to evaluate each survival function before plotting:

I recently wanted to create a development container for VS Code to develop applications using SYCL based on the CUDA backend of the oneAPI DPC++ (Data Parallel C++) compiler. As I’m running Fedora, it seemed natural to use Podman’s rootless containers instead of Docker for this. This turned out to be more challenging than expected, so I’m going to summarize my setup in this post. I’m using Fedora Linux 36 with Podman version 4.1.0.

I’m pleased to announce the release of scikit-survival 0.17.2. This release fixes several small issues with packaging scikit-survival and the documentation. For a full list of changes in scikit-survival 0.17.2, please see the release notes.

Most notably, binary wheels are now available for Linux, Windows, and macOS (Intel). This has been possible thanks to the cibuildwheel build tool, which makes it incredible easy to use GitHub Actions for building those wheels for multiple versions of Python. Therefore, you can now use pip without building everything from source by simply running

pip install scikit-survival

As before, pre-built conda packages are available too, by running

 conda install -c sebp scikit-survival

This release adds support for scikit-learn 1.0, which includes support for feature names. If you pass a pandas dataframe to fit, the estimator will set a feature_names_in_ attribute containing the feature names. When a dataframe is passed to predict, it is checked that the column names are consistent with those passed to fit. The example below illustrates this feature.
