CloakNoiseLayer2 ¶

Bases: CloakNoiseLayer

Stained Glass Transform that stochastically re-represents the input data with masking.

Inspired by the Cloak Step 2 algorithm defined in the paper: Not All Features Are Equal: Discovering Essential Features for Preserving Prediction Privacy

Warning

The directly learned locs and rhos used by this class are prone to vanishing when trained with weight decay regularization. To avoid this, ensure that optimizer parameter group(s) containing locs or rhos are configured with weight_decay=0.0.

Note

For maximum privacy preservation, Stained Glass Transform Step 2 should be pre-trained from a Stained Glass Transform Step 1. For a more convenient type of Stained Glass Transform that requires only one step of training, see CloakNoiseLayerOneShot.

Note

Masking is done using a static threshold on the learned standard deviation of the stochastic transformation. This threshold is calculated from percent_to_mask when loading a pre-trained transform layer. Consequently, continuing to train the stochastic transformation will not affect masking. For a variant of Cloak Step 2 that recalculates its masking using percent_to_mask on each call (i.e. the masking can change during training), see CloakNoiseLayerOneShot.

Parameters:

Name	Type	Description	Default
`input` ¶	`Tensor`	The input to transform.	required
`noise_mask` ¶	`Tensor \| None`	An optional mask that selects the elements of `input` to transform. Where the mask is `False`, the original `input` value is returned.

`**kwargs` ¶	`Any`	Additional keyword arguments to the estimator modules.	required

getstate ¶

__getstate__() -> dict[str, Any]

Prepare a serializable copy of self.__dict__.

init ¶

__init__(input_shape: tuple[int, ...], percent_to_mask: float, scale: tuple[float, float] = (0.0001, 2.0), shallow: float = 1.0, value_range: tuple[float | None, float | None] | None = (-1.0, 1.0), seed: int | None = None) -> None

Construct a CloakNoiseLayer2 with the given parameters.

Parameters:

Name	Type	Description	Default
`input_shape` ¶	`tuple[int, ...]`	The input shape of the layer.	required
`scale` ¶	`tuple[float, float]`	Used to set bound on the min and max standard deviation of the stochastic transformation.	`(0.0001, 2.0)`
`percent_to_mask` ¶	`float`	The percentage of the outputs to mask.	required

CloakNoiseLayerOneShot ¶

Bases: CloakNoiseLayer

Stained Glass Transform inspired by the Cloak Algorithm (see paper), with a threshold that is recalculated every forward pass, to allow for one-step training.

The original Cloak Algorithm requires two steps to train. In the first step, the stochastic mapping is trained, and in the second step, masking is trained. This class allows for training in one step, by recalculating the threshold every forward pass.

For most use cases, this class is preferred over a multi-step Stained Glass Transform version, since it is simpler to use. For more advanced use cases, however, the multi-step version may be required, since it allows for more control over the masking process during training.

Warning

The directly learned locs and rhos used by this class are prone to vanishing when trained with weight decay regularization. To avoid this, ensure that optimizer parameter group(s) containing locs or rhos are configured with weight_decay=0.0.

Examples:

>>> import torch
>>> img_shape = (1, 3, 8, 8)
>>> noise_layer = CloakNoiseLayerOneShot(
...     input_shape=img_shape, percent_to_mask=0.5, scale=(1e-4, 2.0)
... )
>>> img = torch.rand(img_shape)
>>> transformed_img = noise_layer(img)
>>> transformed_img.output.shape == img.shape
True
>>> torch.allclose(transformed_img.output, img)
False

Construct a Stained Glass Transform layer that generates stochastic transformations over patches of the input images.

Parameters:

Name	Type	Description	Default
`input_shape` ¶	`tuple[int, ...]`	Shape of given inputs. The first dimension may be -1, meaning variable batch size.	required
`patch_size` ¶	`int \| tuple[int, int]`	Size of the patches to segment the input into. If an integer is given, a square patch is used.	required
`scale` ¶	`tuple[float, float]`	Minimum and maximum values of the range of standard deviations of the generated stochastic transformation.	`(0.0001, 2.0)`
`shallow` ¶	`float`	A temperature-like parameter which controls the spread of the parameterization function. Controls both the magnitude of parameterized standard deviations and their rate of change with respect to rhos.	`1.0`
`percent_to_mask` ¶	`float \| None`	The percentage of the outputs to mask per patch.	`None`
`value_range` ¶	`tuple[float \| None, float \| None] \| None`	Minimum and maximum values of the range to clamp the output into.	`None`
`padding_mode` ¶	`Literal['constant', 'reflect', 'replicate', 'circular']`	Type of padding. One of: constant, reflect, replicate, or circular. Defaults to constant.	`'constant'`
`padding_value` ¶	`float`	Fill value for constant padding.	`0.0`
`learn_locs_weights` ¶	`bool`	Whether to learn the weight parameters for the locs estimator. If `True`, only the weights will be learned, and the bias remains constant, otherwise weights are initialized to zero and only the bias is learned.	`True`
`freeze_std_estimator` ¶	`bool`	Whether to freeze the weight parameters for the std estimator. If `False`, this estimator will be trained simultaneously with masking and the locs estimator parameters.	`True`
`seed` ¶	`int \| None`	Seed for the random number generator used to generate the stochastic transformation. If `None`, the global RNG state is used.	`None`

Note

For estimators where we train the weights, we freeze their biases. We suspect that if both the biases and weights are trained together, the biases will converge faster than the weights, causing the weights to be trivial. This has not been verified experimentally. Our choices for initialization values and conditions subject to change in light of experimental evidence, and you are encouraged to challenge and improve our understanding of the effects of these choices.
