Probabilistic supervised learning and survival analysis for mlr3

github.com/mlr-org/mlr3proba ↗

mlr3proba is shedding weight as its survival work moves into sibling packages

mlr3survival-analysisprobabilistic-learningdependency-maintenancer-package
◆Current state
mlr3proba provides probabilistic supervised learning for mlr3 — survival analysis, density estimation, and the measures that go with them. Recent releases are almost entirely upkeep: a distr6 fork to work around an upstream problem, an ooplah fix, a predict-type correction, and registration in mlr_reflections$loaded_packages. The one deletion is telling, with LearnerDensPenalized removed after pendensity left CRAN.
◆Where it's heading
The package is being pared back rather than extended. Its README now points at survdistr and mlr3cmprsk as matured alternatives for parts of what it covers, which reads as scope being handed off, while the Cox proportional-hazards autoplot arrived from mlr3viz in the other direction. Several fixes exist to route around dependencies that broke or disappeared, which is the recurring cost of building on a long chain of specialized CRAN packages.
◆Prediction
The dependency churn suggests more consolidation — further reliance on survdistr and mlr3cmprsk, and more learners retired when the package underneath them goes unmaintained.

◆Recent moves

    mlr3proba 0.8.10 registers itself in the mlr3 loaded-packages registry

    Registers mlr3proba in mlr_reflections$loaded_packages. Purely internal bookkeeping for the mlr3 registry.

    mlr3proba 0.8.9 drops LearnerDensPenalized after pendensity left CRAN

    LearnerDensPenalized is removed after pendensity was pulled from CRAN, and the README now points at survdistr and mlr3cmprsk as matured options. A deletion forced upstream, but it marks where scope is moving.

    mlr3proba 0.8.8

    Switches to a distr6 fork to work around an upstream problem. A single dependency change with no user-facing effect.

    mlr3proba 0.8.7

    A single fix to ooplah handling, recorded only as a merged pull request. Routine maintenance.

    mlr3proba 0.8.5

    A predict-type fix plus a CI action bump. Housekeeping between substantive releases.

    mlr3proba 0.8.4 takes over the Cox proportional-hazards autoplot

    Adds an autoplot method for the surv.coxph learner, taking over the plot that mlr3viz previously owned. Small in itself, but it is the concrete step in moving learner-specific plotting to the package that owns the learner.
