Added

Added a notebook demonstrating the Imperceptible ASR evasion attack on the DeepSpeech model for speech recognition tasks. (#639)

Changed

Changed the detection of Keras type (keras vs. tensorflow.keras) in art.estimators.classification.KerasClassifier to enable customised models inheriting from the Keras base models (#631)

[None]

Fixed bug in model-specific estimator for DeepSpeech art.estimators.speech_recognition.PyTorchDeepSpeech to correctly handle the case of batches of samples with identical length including the special case of a batch of a single sample. (#635)
Fixed bug in model-specific estimator for DeepSpeech art.estimators.speech_recognition.PyTorchDeepSpeech by adding missing imports (#621)
Fixed bug to make all tools of ART accessible using import art (#612)
Fixed bug by removing top-level imports of tool-specific dependencies and adapting default values (#613)
Fixed wrong progress bar description in art.attacks.evasion.projected_gradient_descent.* from iterations to batches (#611)
