Struct smartnoise_validator::proto::DpMean

pub struct DpMean {
    pub implementation: String,
    pub mechanism: String,
    pub privacy_usage: Vec<PrivacyUsage>,
}

DPMean Component

Returns differentially private estimates of the means of each column of the data.

This struct represents an abstract computation. Arguments are provided via the graph. Additional options are set via the fields on this struct. The return is the result of the dp_mean on the arguments.

Arguments

• data - Array - Atomic type must be numeric.
• lower - Array - Estimated minimum possible value of the statistic. Only useful for the snapping mechanism.
• upper - Array - Estimated maximum possible value of the statistic. Only useful for the snapping mechanism.

Returns

• Value - Array - Differentially private estimate of the mean of each column of the data.

Fields

implementation: String

Privatizing algorithm to use. One of [resize, plug-in]

mechanism: String

Privatizing mechanism to use. One of [Laplace, Snapping, Gaussian, AnalyticGaussian].

privacy_usage: Vec<PrivacyUsage>

Object describing the type and amount of privacy to be used for the mechanism release. Atomic data type value must be float. Example value: {‘epsilon’: 0.5}
