+        This transform removes the entire row if any of the input columns have a missing value in that row.

+        The TextToKeyConverter transform builds up term vocabularies (dictionaries).
+        The TextToKey Converter and the <see cref="T:Microsoft.ML.Transforms.HashConverter"/> are the two one primary mechanisms by which raw input is transformed into keys.

+        The Key value is the one-based index of the item in the dictionary.
+        If the key is not found in the dictionary, it is assigned the missing value indicator.
+        This dictionary mapping values to keys is most commonly learnt from the unique values in input data,
