pe.dp.dp module

class pe.dp.dp.DP[source]

Bases: ABC

The abstract class for Differential Privacy (DP) histogram mechanism.

abstract add_noise(syn_data)[source]

Add noise to the histogram of synthetic data.

Parameters:

syn_data (pe.data.Data) – The synthetic data to add noise

abstract set_epsilon_and_delta(num_iterations, epsilon, delta, noise_multiplier)[source]

Set the epsilon and delta for the DP mechanism. Either epsilon or noise_multiplier should be None.

Parameters:

  • num_iterations (int) – The number of PE iterations

  • epsilon (float or None) – The epsilon value of DP

  • delta (float) – The delta value of DP

  • noise_multiplier (float or None) – The noise multiplier of the DP mechanism
