smartnoise-synth-logger 0.0.4

A logger wrapper for Smartnoise Synth Table Transformer

Smartnoise Synth Logger

Logger for Smartnoise Synth Transformers

Serialize and deserialize Smartnoise Synth constraints to and from JSON. Constraints as specified in the Smartnoise Synth Transforms documentation: https://docs.smartnoise.org/synth/transforms/index.html with tt = TableTransformer(constraint).

Installation

Install with pip:

pip install smartnoise-synth-logger

Example

from snsynth.transform import (
    AnonymizationTransformer,
    BinTransformer,
    ChainTransformer,
    ClampTransformer,
    DropTransformer,
    LabelTransformer,
    LogTransformer,
    MinMaxTransformer,
    OneHotEncoder,
    StandardScaler,
)

constraints = {
    "id": AnonymizationTransformer("uuid4"),
    "email": "email", # also possible
    "income": ChainTransformer(
        [
            LogTransformer(),
            BinTransformer(bins=20, lower=0, upper=50),
        ]
    ),
    "height": ChainTransformer(
        [
            StandardScaler(lower=0, upper=1),
            BinTransformer(bins=20, lower=0, upper=1),
        ]
    ),
    "weight": ChainTransformer(
        [ClampTransformer(lower=10, upper=200), BinTransformer(bins=20)]
    ),
    "age": MinMaxTransformer(lower=0, upper=100),
    "sex": ChainTransformer(
        [LabelTransformer(nullable=True), OneHotEncoder()]
    ),
    "rank": LabelTransformer(nullable=False),
    "job": DropTransformer(),
}

Serialise

from smartnoise_synth_logger import serialise_constraints

serialised_constraints = serialise_constraints(constraints)

Deserialise

from smartnoise_synth_logger import deserialise_constraints

deserialised_constraints = deserialise_constraints(serialised_constraints)
tt = TableTransformer(deserialised_constraints)

It can now be expected that the deserialised_constraints has the same constraints as constraints.

NOTE: lambda function in AnonymizationTransformer are not supported.
