Constructors
IDFModel() |
Create a IDFModel without any parameters |
IDFModel(String) |
Create a IDFModel with a UID that is used to give the IDFModel a unique ID |
Methods
Clear(Param) |
Clears any value that was previously set for this Microsoft.Spark.ML.Feature.Param. The value is reset to the default value. (Inherited from FeatureBase<T>) |
ExplainParam(Param) |
Returns a description of how a specific Microsoft.Spark.ML.Feature.Param works and is currently set. (Inherited from FeatureBase<T>) |
ExplainParams() |
Returns a description of how all of the Microsoft.Spark.ML.Feature.Param's that apply to this object work and how they are currently set. (Inherited from FeatureBase<T>) |
GetInputCol() |
Gets the column that the IDFModel should read from |
GetMinDocFreq() |
Minimum of documents in which a term should appear for filtering |
GetOutputCol() |
The IDFModel will create a new column in the DataFrame, this is the name of the new column. |
GetParam(String) |
Retrieves a Microsoft.Spark.ML.Feature.Param so that it can be used to set the value of the Microsoft.Spark.ML.Feature.Param on the object. (Inherited from FeatureBase<T>) |
Load(String) |
Loads the IDFModel that was previously saved using Save |
Save(String) |
Saves the object so that it can be loaded later using Load. Note that these objects can be shared with Scala by Loading or Saving in Scala. (Inherited from FeatureBase<T>) |
Set(Param, Object) |
Sets the value of a specific Microsoft.Spark.ML.Feature.Param. (Inherited from FeatureBase<T>) |
SetInputCol(String) |
Sets the column that the IDFModel should read from and convert into buckets |
SetOutputCol(String) |
The IDFModel will create a new column in the DataFrame, this is the name of the new column. |
ToString() |
Returns the JVM toString value rather than the .NET ToString default (Inherited from FeatureBase<T>) |
Transform(DataFrame) |
Executes the IDFModel and transforms the DataFrame to include the new column or columns with the tokens. |
Uid() |
The UID that was used to create the object. If no UID is passed in when creating the object then a random UID is created when the object is created. (Inherited from FeatureBase<T>) |
