Overview

An information specific to given column and Tables Model, in context of the Model and the predictions created by it.

Instance Attribute Summary

• #column_id ⇒ Fixnum

  The ID of the column.

• #feature_importance ⇒ Float

  When given as part of a Model: Measurement of how much model predictions correctness on the TEST data depend on values in this column.

Instance Method Summary

• #initialize(**args) ⇒ XpsTablesModelColumnInfo constructor

  A new instance of XpsTablesModelColumnInfo.

• #update!(**args) ⇒ Object

  Update properties of this object.

Constructor Details

#initialize(**args) ⇒ XpsTablesModelColumnInfo

# File 'lib/google/apis/language_v2/classes.rb', line 3760

def initialize(**args)
   update!(**args)
end

Instance Attribute Details

#column_id ⇒ Fixnum

The ID of the column. Corresponds to the JSON property columnId

Returns:

• (Fixnum)

# File 'lib/google/apis/language_v2/classes.rb', line 3745

def column_id
  @column_id
end

#feature_importance ⇒ Float

When given as part of a Model: Measurement of how much model predictions correctness on the TEST data depend on values in this column. A value between 0 and 1, higher means higher influence. These values are normalized - for all input feature columns of a given model they add to 1. When given back by Predict or Batch Predict: Measurement of how impactful for the prediction returned for the given row the value in this column was. Specifically, the feature importance specifies the marginal contribution that the feature made to the prediction score compared to the baseline score. These values are computed using the Sampled Shapley method. Corresponds to the JSON property featureImportance

Returns:

• (Float)

# File 'lib/google/apis/language_v2/classes.rb', line 3758

def feature_importance
  @feature_importance
end

Instance Method Details

#update!(**args) ⇒ Object

def update!(**args)
  @column_id = args[:column_id] if args.key?(:column_id)
  @feature_importance = args[:feature_importance] if args.key?(:feature_importance)
