DataStructures

StringToInt64Map

message StringToInt64Map {
    map<string, int64> map = 1;
}

Int64ToStringMap

A mapping from a 64-bit integer to a string.

message Int64ToStringMap {
    map<int64, string> map = 1;
}

StringToDoubleMap

A mapping from a string to a double-precision floating point number.

message StringToDoubleMap {
    map<string, double> map = 1;
}

Int64ToDoubleMap

A mapping from a 64-bit integer to a double-precision floating point number.

message Int64ToDoubleMap {
    map<int64, double> map = 1;
}

StringVector

A vector of strings.

message StringVector {
    repeated string vector = 1;
}

Int64Vector

A vector of 64-bit integers.

message Int64Vector {
    repeated int64 vector = 1;
}

FloatVector

A vector of floating point numbers.

message FloatVector {
    repeated float vector = 1;
}

DoubleVector

A vector of double-precision floating point numbers.

message DoubleVector {
    repeated double vector = 1;
}

Int64Range

A range of int64 values

message Int64Range {
    int64 minValue = 1;
    int64 maxValue = 2;
}

Int64Set

A set of int64 values

message Int64Set {
    repeated int64 values = 1;
}

DoubleRange

A range of double values

message DoubleRange {
    double minValue = 1;
    double maxValue = 2;
}

PrecisionRecallCurve

The syntax comprises two tables: one to look up the precision value threshold for a given precision, and the other for a given recall.

Example
`precisionValues`	.1	.2	.3	.4	.5	.6	.7
`precisionConfidence`	.0	.0	.0	.0	.1	.3	.4
`recallValues`	.1	.2	.3	.4	.5	.6	.7	.8	.9
`recallConfidence`	.7	.6	.5	.4	.3	.3	.2	.1	.0

The application expects that, when it filters out samples with confidence threshold = 0.1, it gets precision = 0.5. Likewise, with threshold = 0.2 it gets recall = 0.7.

The table must have only valid values; do not use NaN, +/- INF, or negative values. The application is responsible for inter/extrapolating the appropriate confidence threshold based on the application’s specific need.

message PrecisionRecallCurve {
    FloatVector precisionValues = 1;
    FloatVector precisionConfidenceThresholds = 2;
    FloatVector recallValues = 3;
    FloatVector recallConfidenceThresholds = 4;
}
