Transformations
A transformation is a method which perturbs a text input through the insertion, deletion and substiution of words, characters, and phrases. All transformations take a TokenizedText as input and return a list of TokenizedText that contains possible transformations. Every transformation is a subclass of the abstract Transformation class.

Composite Transformation
Multiple transformations can be used by providing a list of Transformation to CompositeTransformation
- class textattack.transformations.composite_transformation.CompositeTransformation(transformations)[source]
Bases:
TransformationA transformation which applies each of a list of transformations, returning a set of all optoins.
- Parameters:
transformations – The list of
Transformationto apply.
Transformation Abstract Class
- class textattack.transformations.transformation.Transformation[source]
Bases:
ReprMixin,ABCAn abstract class for transforming a sequence of text to produce a potential adversarial example.
- property deterministic
word deletion Transformation
- class textattack.transformations.word_deletion.WordDeletion[source]
Bases:
TransformationAn abstract class that takes a sentence and transforms it by deleting a single word.
letters_to_insert (string): letters allowed for insertion into words
Word Swap Transformation by swapping the order of words
- class textattack.transformations.word_innerswap_random.WordInnerSwapRandom[source]
Bases:
TransformationTransformation that randomly swaps the order of words in a sequence.
- property deterministic
