mlr3proba 0.6.6

• Some fixes from v0.6.5

mlr3proba 0.6.5

• Compatibility with [email protected]
• t_max updates and fixes on surv.cindex and surv.ibrier metrics
• New methods to TaskSurv
• coxed task generator
• Lots of refactoring
• Support for discrete-time survival analysis

mlr3proba 0.6.0

• Optimized surv.logloss and calib_alpha measures (bypassing distr6)
• Update/refine all measure docs (naming conventions from upcoming scoring rules paper) + doc templates
• fix very rare bugs in calib_alpha, surv.logloss and surv.graf (version with proper = FALSE)

mlr3proba 0.5.7

What's Changed

• Add breslow function for estimating the cumulative baseline hazard of proportional hazard models
• Add PipeOpBreslow to wrap a survival learner and generate distr predictions from lp predictions
• Add option breslow estimator option in distrcompositor
• Add extend_quantile to autoplot.PredictionSurv for type = "dcalib", which imputes NAs with the maximum observed survival time
• Fixes default in autoplot.PredictionSurv, now "calib"
• Update msr("surv.dcalib") default for truncate to Inf
• Add $reverse() method to TaskSurv, which returns the same task but with 1-status.
• Add reverse parameter to TaskSurv$kaplan() method, which calculates Kaplan-Meier on the censoring distribution of the task (1-status).
• Fix bottlenecks in Dcalib and RCLL

Full Changelog: v0.4.7...v0.4.13

mlr3proba 0.4.7

mlr3proba 0.4.7

• Add right-censored log loss
• Fix bug in {rpart} where model was being discarded when set to be kept. Parameter model now called keep_model.

mlr3proba 0.4.6

• Patch for upstream breakages
• Add TaskSurv$kaplan method
• {survivalmodels} now imported (previously suggested)

mlr3proba 0.4.5

• Improved reduction from survival matrix predictions to ranking predictions
• Fixed cindex bug when all predictions equal
• Fix for valgrind

mlr3proba 0.4.4

• Minor change to how distributions are created to better support improper distributions
• Fixed bug in simsurv task that made it impossible to predict the target

mlr3proba 0.4.3

• Massive speed-up in distrcompositor PipeOp/pipeline
• More informative error given if $distr called for a learner that does not support this return type
• Fix massive bottleneck in scoring rule measures
• Add Density coercions as_task_dens and as_prediction_dens
• Measures now use parameter sets like learners. This streamlines the interface but unfortunately means ids can no longer be set dynamically.
• Add parameters t_max and p_max to Graf, Schmid and Integrated Log-loss as an alternative to times. t_max is equivalent to times = seq(t_max) and p_max is the proportion of censoring to integrate up to in the dataset.
• Fix bug in Rcpp code that was causing erroneous values for calculating the cindex in datasets greater than 20,000 observations.
