Struct smartnoise_validator::proto::DpQuantile

pub struct DpQuantile {
    pub alpha: f64,
    pub mechanism: String,
    pub privacy_usage: Vec<PrivacyUsage>,
    pub interpolation: String,
}

DPQuantile Component

Returns differentially private estimates of specified quantiles for 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_quantile on the arguments.

Arguments

• data - Array - Atomic type must be numeric.
• candidates - Array - Set from which the Exponential mechanism will return an element. Type must match with atomic type of data. This value must be column-conformable with data. Only useful for Exponential mechanism.
• 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 quantile.

Fields

alpha: f64

Desired quantiles, defined on [0,1].

mechanism: String

Privatizing mechanism to use. Value must be one of [Automatic, Exponential, Laplace, Snapping, Gaussian, AnalyticGaussian]. Automatic chooses Exponential if candidates provided.

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}

interpolation: String

Interpolation strategy. One of [lower, upper, midpoint, nearest, linear]
