embed 1.2.1

Improvements

• Make work with all versions of xgboost. (#267)

embed 1.2.0

Improvements

• Adds step_lencode() to perform analytical likelihood encoding. (#258)

• Adds smooth argument to step_lencode() to allow for partial pooling in numeric outcomes. (#261)

• step_feature_hash() has been fully deprecated in favor of textrecipes::step_dummy_hash(). (#253)

embed 1.1.5

Improvements

• step_umap() has tunable initial and target_weight arguments. (#223, #222)

• All messages, warnings and errors has been translated to use {cli} package (#153, #155).

embed 1.1.4

Improvements

• step_umap() has gained initial and target_weight arguments. (#213)

• Calling ?tidy.step_*() now sends you to the documentation for step_*() where the outcome is documented. (#216)

• Documentation for tidy methods for all steps has been improved to describe the return value more accurately. (#217)

• {keras} and {tensorflow} have been moved to Suggests instead of Imports. (#218)

embed 1.1.3

• step_collapse_stringdist() will now return predictors as factors. (#204)

• Fixed regression from 1.1.2 in step_lencode_glm() where it couldn't be used on multiple columns.

embed 1.1.2

Improvements

• The keep_original_cols argument has been added to step_woe(). This change should mean that every step that produces new columns has the keep_original_cols argument. (#194)

• Many internal changes to improve consistency and slight speed increases.

Breaking Changes

• step_pca_sparse(), step_pca_truncated() and step_pca_sparse_bayes() now returns data unaltered if num_comp = 0. This is done to be consistent with recipes steps of the same nature. (#190)

embed 1.1.1

Bug Fixes

• Fixed bug where step_pca_truncated() didn't work with zero selection. (#181)

• The tidy() methods for step_discretize_cart(), step_discretize_xgb(), step_embed(), step_feature_hash(), step_lencode_bayes(), step_lencode_glm(), step_lencode_mixed(), step_pca_sparse(), step_pca_sparse_bayes(), step_pca_truncated(), step_umap(), and step_woe() now correctly return zero-row tibbles when used with empty selections. (#181)

embed 1.1.0

New Steps

• step_pca_truncated() has been added. This step only calculates the components that are required, and will be a speedup in cases where it is used on many variables. (#82)

Improvements

• step_collapse_stringdist() has gained method and options arguments to allow for different types of string distance calculations. (#152)

• step_umap() has gained the argument metric. (#154)

• step_embed() has gained the keep_original_cols argument. (#176)

• All steps now have required_pkgs() methods.

• Steps with tunable arguments now have those arguments listed in the documentation.

• All steps that add new columns will now informatively error if name collision occurs.

embed 1.0.0

• step_collapse_cart() can pool a predictor's factor levels using a tree-based method.

• step_collapse_stringdist() can pool a predictor's factor levels using string distances.

• Case weights support have been added to step_discretize_cart(), step_discretize_xgb(), step_lencode_bayes(), step_lencode_glm(), and step_lencode_mixed().

embed 0.2.0

• step_embed() now correctly defaults to have a random id with the word "embed". (#102)

• step_feature_hash() is soft deprecated in embed in favor of step_dummy_hash() in textrecipes. (#95)

• Steps now have a dedicated subsection detailing what happens when tidy() is applied. (#105)

• Reorganize documentation for all recipe step tidy methods (#115).

• Fixed a bug where woe_table() and step_woe() didn't respect the factor levels of the outcome. (109)
