Class: StringIndexerModel

eclairjs/ml/feature.StringIndexerModel

Model fitted by module:eclairjs/ml/feature.StringIndexer. NOTE: During transformation, if the input column does not exist, module:eclairjs/ml.Transformer#transform would return the input dataset unmodified. This is a temporary fix for the case when target labels do not exist during prediction.

Constructor

new StringIndexerModel(labels, uidopt)

Parameters:
Name Type Attributes Description
labels Array.<string> Ordered list of labels, corresponding to indices to be assigned.
uid string <optional>
