Thanks to the following people for contributing to this release: @frances-h, @gsheni, @rwedge, @tamargrey, @thehomebrewnerd, @tuethan1999

Breaking Changes

  • ft.dfs will no longer build features from Transform primitives where one of the inputs is a Transform feature, a GroupByTransform feature, or a Direct Feature of a Transform / GroupByTransform feature.

Breaking Changes

  • Calls to featuretools.dfs or featuretools.calculate_feature_matrix that use a cutoff time dataframe, but do not label the time column with either the target entity time index variable name or as time, will now result in an AttributeError. Previously, the time column was selected to be the first column that was not the instance id column. With this update, the position of the column in the dataframe is no longer used to determine the time column. Now, both instance id columns and time columns in a cutoff time dataframe can be in any order as long as they are named properly.

  • The type_string attributes of all Variable subclasses are now a snake case conversion of their class names. This changes the type_string of the Unknown, IPAddress, EmailAddress, SubRegionCode, FilePath, LatLong, and ZIPcode classes. Old saved entitysets that used these variables may load incorrectly.

v0.14.0 Apr 30, 2020
  • Enhancements

    • Fix Github links with correct organizations (GH#908)

    • Fix hyperlinks in docs and docstrings with updated address (GH#910)

    • Remove unused script for uploading docs to AWS (GH#911)

Thanks to the following people for contributing to this release: @frances-h, @gsheni, @jeff-hernandez, @rwedge

Breaking Changes

  • Using training windows in feature calculations can result in different values than previous versions. This was done to prevent consecutive training windows from overlapping by excluding data at the oldest point in time. For example, if we use a cutoff time at the first minute of the hour with a one hour training window, the first minute of the previous hour will no longer be included in the feature calculation.

Breaking Changes

  • ft.dfs now has a groupby_trans_primitives parameter that DFS uses to automatically construct features that group by an ID column and then apply a transform primitive to search group. This change applies to the following primitives: CumSum, CumCount, CumMean, CumMin, and CumMax.

    Previous behavior

    ft.dfs(entityset=es,
           target_entity='customers',
           trans_primitives=["cum_mean"])
    

    New behavior

    ft.dfs(entityset=es,
           target_entity='customers',
           groupby_trans_primitives=["cum_mean"])
    
  • Related to the above change, cumulative transform features are now defined using a new feature class, GroupByTransformFeature.

    Previous behavior

    ft.Feature([base_feature, groupby_feature], primitive=CumulativePrimitive)
    

    New behavior

    ft.Feature(base_feature, groupby=groupby_feature, primitive=CumulativePrimitive)
