Struct TripletLoss

Source 
pub struct TripletLoss {
    pub axis: i32,
    pub p: f32,
    pub margin: f32,
    pub eps: f32,
    pub reduction: LossReduction,
}
Expand description

Computes the triplet loss for a set of anchor, positive, and negative samples. Margin is represented with alpha in the math section.

Fields§

§axis: i32

Distribution axis. Default to TripletLoss::DEFAULT_AXIS

§p: f32

The norm degree for pairwise distance. Default to TripletLoss::DEFAULT_P

§margin: f32

Margin for the triplet loss. Default to TripletLoss::DEFAULT_MARGIN

§eps: f32

Small positive constant for numerical stability. Default to TripletLoss::DEFAULT_EPS

§reduction: LossReduction

Reduction type. Default to TripletLoss::DEFAULT_REDUCTION
