Changelog • tabnet

tabnet 0.8.0

messaging is now improved with {cli}
add optimal threshold and support size into new 1.5 alpha entmax15() and sparsemax15() mask_types. Add an optional mask_topk config parameter. (#180)
optimizernow default to the torch_ignite_adam when available. Result is 30% faster pretraining and fitting tasks (#178).
add nn_aum_loss() function for area under the $Min(FPR,FNR)$ optimization for cases of unbalanced binary classification (#178).
add a vignette on imbalanced binary classification with nn_aum_loss() (#178).

config parameter now merge correctly for torch loss or torch optimizer generator.
nn_unsupervised_loss() is now a proper loss function.

Remove long-run example raising a Note.
fix tabet_pretrain failing with value_error("Can't convert data of class: 'NULL'") in R 4.5
fix tabet_pretrain wrongly used instead of tabnet_fit in Missing data predictor vignette
improve message related to case_weights not being used as predictors.
improve function documentation consistency before translation.
fix “…” is not an exported object from ‘namespace:dials’” error when using tune() on tabnet parameters. (#160 @cphaarmeyer)
