Requirements (5 changes)

#623 secml is now tested for compatibility with Python 3.8.
#623 The following dependencies are now required: scipy >= 1.3.2, scikit-learn >= 0.22, matplotlib >= 3.
#623 The pytorch extra component now installs: torch >= 1.4, torchvision >= 0.5.
#623 The cleverhans extra component is now available on Python < 3.8 only, due to tensorflow 1 compatibility.

Added (3 changes)

#795 Added new package adv.attacks.evasion.foolbox with a wrapper for Foolbox.
#880 Added new shape parameter to the following CArray methods: get_data, tondarray, tocsr, tocoo, tocsc, todia, todok, tolil, tolist. The reshaping operation is performed after casting the array to the desired output data format.

Improved (3 changes)

#861 N-Dimensional input is now accepted by CArray. If the number of dimensions of input data is higher than 2, the data is reshaped to 2 dims, and the original shape is stored in the new attribute input_shape.
#910 The MNIST dataset loader CDataLoaderMNIST now downloads the files from our model-zoo mirror (https://gitlab.com/secml/secml-zoo/-/tree/datasets/MNIST).
#886 Torch datasets now stored by CDataLoaderTorchDataset in a "pytorch" subfolder of SECML_DS_DIR to avoid naming collisions.

Fixed (8 changes)

#897 Fixed crash in CAttackPoisoning when y_target != None due to missing broadcasting to expected shape.
#873 Use equality instead of identity to compare literals (fixing related SyntaxWarning in Python 3.8).

#871 Fixed ValueError: k exceeds matrix dimensions not raised by scipy v1.5 if a k outside the array dimensions is used to extract a diagonal.
#872 Fixed scipy 1.5 not always keeping the dtype of the original array during getitem (especially if the result is an empty array).

CHANGELOG

#814 Added new evasion attack CAttackEvasionPGDExp.
#780 Added new classifier CClassifierDNR implementing Deep Neural Rejection (DNR). See Sotgiu et al. “Deep neural rejection against adversarial examples”, EURASIP J. on Info. Security (2020).
#47 Added new classifier CClassifierMulticlassOVO implementing One-vs-One multiclass classification scheme.
#765 Extended CModule to support trainable modules via fit and fit_forward functions.
#800 Security evaluation can now be run using Cleverhans attacks. The name of the parameter to check should be specified as attack_params.<param_name> as an input argument for the constructor of CSecEval.
#839 Experimental support of Windows operating system (version 7 or later).

Requirements (1 change)

#768 Removed temporary pin of Pillow to v6 which used to break torch and torchvision packages.

Added (4 changes)

#100007 Added new experimental package ml.scalers with a different implementation of ml.features.normalization classes directly based Scikit-Learn's scalers. Included classes are: CScalerMinMax, CScalerStd, CScalerNorm.
#770 Added new methods to convert a CArray to specific scipy.sparse array formats: tocoo, tocsc, todia, todok, tolil.
#812 CAttackPoisoning now exposes: x0, xc, yc, objective_function and objective_function_gradient.
#776 n_jobs is now a init parameter of CModule and subclasses and not passed via fit anymore.

Improved (12 changes)

#817 Added CClassifierSVM native support to OVA multiclass scheme, without replicating the kernel in each one-vs-all classifier.
#574 Added _clear_cache mechanism to CModule and classes that require caching data in the forward pass before backward (e.g., exponential kernels do that to avoid re-computing the kernel matrix in the backward pass).
#820 Add parallel execution of forward method for CClassifierMulticlassOVA and CClassifierMulticlassOVO.
#815 Simplified CAttack interface (now only requires implementing run as required by CSecEval).
#574 Modified kernel and classifier interfaces to allow their use as preprocessing modules.
#775 Improved efficiency in gradient computation of SVMs, by back-propagating the alpha values to the kernel.
#773 Improved efficiency in the computation of gradients of evasion attacks (CAttackEvasionPGDLS). Now gradient is called once rather than twice to compute the gradient of the objective function.
#801 CSecEval will now check that the param_name input argument can be found in the attack class used in the evaluation.
#695 COptimizerPGD now exits optimization if constraint radius is 0. COptimizerPGD , COptimizerPGDLS and COptimizerPGDExp will now raise a warning if the 0-radius constraint is defined outside the given bounds.
#828 CClassifierSVM now uses n_jobs parameter for parallel execution of training in case of multiclass datasets.
#767 Using scipy.sparse .hstack and .vstack instead of a custom implementation in CSparse.concatenate.
#772 Using scipy.sparse .argmin and .argmax instead of a custom implementation in CSparse.argmin and CSparse.argmax.

Changed (6 changes)

#817 Kernel is now used as preprocess in CClassifierSVM.
#817 Removed store_dual_vars and kernel.setter from CClassifierSVM. Now a linear SVM is trained in the primal (w,b) if kernel=None, otherwise it is trained in the dual (alpha and b), on the precomputed training kernel matrix.
#765 Unified fit interface from fit(ds) to fit(x,y) to be consistent across normalizers and classifiers.
#574 Removed redundant definitions of gradient(x, w) from CKernelRBF, CKernelLaplacian, CKernelEuclidean, CClassifierDNN, CNormalizerUnitNorm. The protected property grad_requires_forward now specifies if gradient has to compute an explicit forward pass or only propagate the input x through the pre-processing chain before calling backward.
#823 Removed surrogate_data parameter from CAttackPoisoning and renamed it to double_init_ds in CAttackEvasion subclasses.
#829 CClassifierRejectThreshold now returns wrapped classifier classes plus the reject class (-1).

Fixed (10 changes)

#816 Fixed stop condition of COptimizerPGD which was missing index i.
#825 Infer the number of attacked classifier classes directly from it (instead of inferring it from surrogate data) in CAttackEvasionPGDLS to fix a crash when the class index of data points is greater or equal than the number of alternative data points.
#810 Fixed CClassifierPyTorch.backward not working properly due to a miscalculation of the number of input features of the model when a CNormalizeDNN is used as preprocessor.
#803 Fixed checks on the inner classifier in CClassifierRejectThreshold which can be bypassed by using the clf attribute setter, now removed.
#818 Fixed CCreator.set not allowing to set writable attributes of level-0 readable-only attributes.
#819 Fixed CCreator.get_params not returning level-0 not-writable attributes having one or more writable attributes.
#785 Fixed constant override of matplotlib backend in CFigure on Windows systems.
#783 Fixed model_zoo.load_model improperly building download urls depending on the system default url separator.
#771 Fixed the following methods of CSparse to ensure they properly work independently from the sparse array format: save, load, __pow__, round, nan_to_num, logical_and, unique, bincount, prod, all, any, min, max.
#769 CArray.tocsr() now always returns a scipy.sparse.csr_matrix array as expected.

Removed & Deprecated (2 changes)

#540 Removed discrete and surrogate_classifier parameter from CAttack.
#777 Deprecated attribute kernel is now removed from CClassifierSGD, CClassifierRidge and CClassifierLogistic classifiers.

Documentation (10 changes)

#839 Windows is now displayed as a supported Operating System in README and setup.
#806 Documented pytorch extra component installation requirements under Windows.
#834 Temporarily pinned numpydoc to < 1.1 to avoid compatibility issues of the newest version.
#807 Documentation is now built using Sphinx https://readthedocs.org/ theme v0.5 or higher.
#830 Fixed links to repository pages by adding a dash after project name.
#758 Added a direct link to the gitlab.com repository in README.
#788 Notebooks now include a warning about the required extra components (if any).
#787 Fixed argmin -> argmax typo in docstring of CClassifierRejectThreshold.predict method.
#789 Fixed notebook 4 not correctly generating a separate dataset for training the target classifiers.
#791 Fixed random_state not set for CClassifierDecisionTree in notebook 4.
