mlr3proba 0.2.0 2020-07-25

Added Functionality

  • MeasureSurvCindex added. Generalises all c-index measures with a fast C++ implementation
  • Akritas estimator added to mlr3learners/mlr3learners.proba
  • Added scoring rule MeasureSurvSchmid
  • Addd calibration measures MeasureSurvCalibrationBeta and MeasureSurvCalibrationAlpha
  • surv.brier alias added for surv.graf
  • response parameter added to PipeOpCrankCompositor and crankcompositor to now optionally fill response predict type with same values as crank
  • Added PipeOpProbregrCompostior and compose_probregr for composition to distr return type from (a) regression learner(s) predicting response and se
  • Added PipeOpSurvAvg and surv_averager pipeline for weighted model averaging of distr, lp, crank, and response predictions.

Deprecated Functionality

  • The following measures are deprecated use MeasureSurvCindex instead with following parameters: MeasureSurvBeggC, use defaults; MeasureSurvHarrellC, use defaults; MeasureSurvUnoC, use weight_meth = 'G/2'; MeasureSurvGonenC, use weight_method = 'GH'
  • MeasureSurvGrafSE, MeasureSurvLoglossSE, MeasureSurvIntLoglossSE, MeasureSurvRMSESE, MeasureSurvMSESE, and MeasureSurvMAESE all deprecated and will be deleted in v0.4.0. Use msr("surv.graf", se = TRUE) instead (for example).
  • Measures renamed such that surv.nagelkR2 is now surv.nagelk_r2, analogously for all R2, AUC, TPR, and TNR measures. Old constructors will be deleted in v0.4.0.
  • Renamed distrcompose and crankcompose to distr_compose and crank_compose. Old ids will be deleted in v0.4.0.

Edited Functionality

  • Measures renamed such that surv.nagelkR2 is now surv.nagelk_r2, analogously for all R2, AUC, TPR, and TNR measures. Old constructors will be deleted in v0.4.0.
  • MeasureSurvGraf and MeasureSurvIntLogloss now have much faster C++ implementation

Moved Functionality

mlr3proba 0.1.6 2020-06-05

  • Early release due to backward compatibility error introduced by an upstream dependency
  • Minor updates to mboost family of learners: added gehan family, fixed parameters for cindex, added support for: weights, response predict type, importance, selected_features
  • Minor internal changes
  • All density learners except LearnerDensHist and LearnerDensKDE have been moved to the mlr3learners org
  • The following survival learners have been moved to the mlr3learners org, LearnerSurv: Flexible, ObliqueRSF, Penalized, RandomForestSRC
  • Bugfix in LearnerSurvXgboost previously lp was erroneously returned as exp(lp)
  • Now licenced under LPGL-3

mlr3proba 0.1.5 2020-04-16

  • LearnerSurvParametric and LearnerSurvNelson moved to mlr3learners/mlr3learners.survival repo
  • LearnerSurvCoxboost and LearnerSurvCVCoxboost moved to mlr3learners/mlr3learners.coxboost repo
  • LearnerSurvSVM moved to mlr3learners/mlr3learners.survivalsvm repo
  • In the next release, all learners except for LearnerSurvKaplan, LearnerSurvCoxPH, and LearnerDensHist will be moved to the mlr3learners org
  • Minor internal changes

mlr3proba 0.1.4 2020-03-20

  • Density estimation has now been added to mlr3proba, see TaskDens, LearnerDens, PredictionDens, and MeasureDens.
  • Added mlr_tasks_faithful and mlr_tasks_precip for density task examples
  • Added mlr_task_generators_simdens for generating density tasks
  • Added learners for density estimation, see mlr3::mlr_learners$keys("^dens") for the full list

  • Converted to roxygen2 R6 documentation

mlr3proba 0.1.3 2020-02-20
