mlr3 and mlr3proba
mlr3proba is a specialized extension package that adds probabilistic prediction capabilities (survival analysis, density estimation, distributional regression) to mlr3's core machine learning framework, making them complements designed to be used together.

mlr3: Machine Learning in R - next generation
Built on R6 object-oriented classes and data.table for efficient computation, mlr3 provides modular building blocks for tasks, learners, and resampling strategies that can be composed and extended through a rich ecosystem of packages like mlr3tuning, mlr3pipelines, and mlr3learners. The architecture prioritizes extensibility by keeping the core lightweight while delegating specialized functionality (visualization, additional learners, autoML) to optional extension packages. Integrates with standard R workflows via checkmate for type safety and supports diverse learner backends through a unified interface.
