Enum nblast::Symmetry

source · 
pub enum Symmetry {
    ArithmeticMean,
    GeometricMean,
    HarmonicMean,
    Min,
    Max,
}
Expand description

Enumeration of methods to ensure that queries are symmetric/ commutative (i.e. f(q, t) = f(t, q)). Specific applications will require different methods. Geometric and harmonic means bound the output to be >= 0.0. Geometric mean may work best with non-normalized queries. Max may work if an unknown one of the query and target is incomplete.
