 Transforms the input dataset.  
 Specified by:  
 `[transform](../../../../../org/apache/spark/ml/Transformer.html#transform-org.apache.spark.sql.Dataset-)` in class `[Transformer](../../../../../org/apache/spark/ml/Transformer.html "class in org.apache.spark.ml")`

 Check transform validity and derive the output schema from the input schema.  
  We check validity for interactions between parameters during `transformSchema` and raise an exception if any parameter value is invalid. Parameter value checks which do not depend on other parameters are handled by `Param.validate()`.  
  Typical implementation should first conduct verification on schema change and parameter validity, including complex parameter interaction checks.
