Struct smartnoise_validator::proto::DpMaximum

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

DPMaximum Component

Returns differentially private estimates of the maximum elements 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_maximum on the arguments.

Arguments

• data - Array
• 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 estimates of the maximum elements of the data.

Fields

mechanism: String

Privatizing mechanism to use. Value must be one of [Automatic, 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}
