New Features

  • finetune now fully supports models in the "censored regression" mode. These models can be fit, tuned, and evaluated like the regression and classification modes. tidymodels.org has more information and tutorials on how to work with survival analysis models.

  • Improved error message from tune_sim_anneal() when values in the supplied param_info do not encompass all values evaluated in the initial grid. This most often happens when a user mistakenly supplies different parameter sets to the function that generated the initial results and tune_sim_anneal().

  • autoplot() methods for racing objects will now use integers in x-axis breaks (#75).

  • Enabling the verbose_elim control option for tune_race_anova() will now additionally introduce a message confirming that the function is evaluating against the burn-in resamples.

  • Updates based on the new version of tune, primarily for survival analysis models (#104).

Bug Fixes

  • Fixed bug where tune_sim_anneal() would fail when supplied parameters needing finalization. The function will now finalize needed parameter ranges internally (#39).

  • Fixed bug where packages specified in control_race(pkgs) were not actually loaded in tune_race_anova() (#74).

Breaking Change

  • Ellipses (...) are now used consistently in the package to require optional arguments to be named. collect_predictions(), collect_metrics() and show_best() methods previously had ellipses at the end of the function signature that have been moved to follow the last argument without a default value. Optional arguments previously passed by position will now error informatively prompting them to be named (#105).
