Struct BinaryCrossEntropyLossConfig

pub struct BinaryCrossEntropyLossConfig {
    pub weights: Option<Vec<f32>>,
    pub smoothing: Option<f32>,
    pub logits: bool,
}

Configuration to create a Binary Cross-entropy loss using the init function.

Fields

weights: Option<Vec<f32>>

Create weighted binary cross-entropy with a weight for each class.

The loss of a specific sample will simply be multiplied by its label weight.

smoothing: Option<f32>

Create binary cross-entropy with label smoothing according to When Does Label Smoothing Help?.

Hard labels {0, 1} will be changed to y_smoothed = y(1 - a) + a / num_classes. Alpha = 0 would be the same as default.

logits: bool

Treat the inputs as logits, applying a sigmoid activation when computing the loss.
