v0.6.0

v0.6.0 (2021-04-12)

Full Changelog

Added

• Flexible backend support (TensorFlow and PyTorch) for drift detectors MMDDrift and ClassifierDrift as well as support for both frameworks for preprocessing steps (from alibi_detect.cd.tensorflow import HiddenOutput, preprocess_drift and from alibi_detect.models.tensorflow import TransformerEmbedding, replace tensorflow with pytorch for PyTorch support) and various utility functions (kernels and distance metrics) under alibi_detect.utils.tensorflow and alibi_detect.utils.pytorch.
• Significantly faster implementation MMDDrift detector leveraging both GPU implementations in TensorFlow and PyTorch as well as making efficient use of the cached kernel matrix for the permutation tests.
• Change test for ChiSquareDrift from goodness-of-fit of the observed data against the empirical distribution of the reference data to a test for homogeneity which does not bias p-values as much to extremes.
• Include NumpyEncoder in library to facilitate json serialization.

Removed

• As part of the introduction of flexible backends for various drift detectors, dask is no longer supported for the MMDDrift detector and distance computations.

Fixed

• Update RTD theme version due to rendering bug.
• Bug when using TabularDrift with categorical features and continuous numerical features. Incorrect indexing of categorical columns was performed.

Development

• Pin pystan version to working release with prophet.
