Struct BinaryCrossEntropyLoss 

pub struct BinaryCrossEntropyLoss {
    pub logits: bool,
}

Calculate the binary cross entropy loss from the input logits and the targets.

Should be created using BinaryCrossEntropyLossConfig

Fields

logits: bool

Treat the inputs as logits

Implementations

impl BinaryCrossEntropyLoss

pub fn forward<const D: usize, B: Backend>( &self, logits: Tensor<B, D>, targets: Tensor<B, D>, ) -> Tensor<B, 1>

Compute the criterion on the input tensor.

Shapes

Binary:

• logits: [batch_size]
• targets: [batch_size]

Multi-label:

• logits: [batch_size, num_classes]
• targets: [batch_size, num_classes]
