Struct ClassificationOutput 

Source 
pub struct ClassificationOutput<B: Backend> {
    pub loss: Tensor<B, 1>,
    pub output: Tensor<B, 2>,
    pub targets: Tensor<B, 1, Int>,
}
Expand description

Simple classification output adapted for multiple metrics.

Supported metrics:

  • Accuracy
  • AUROC
  • TopKAccuracy
  • Perplexity
  • Precision (via ConfusionStatsInput)
  • Recall (via ConfusionStatsInput)
  • FBetaScore (via ConfusionStatsInput)
  • Loss.

Fields§

§loss: Tensor<B, 1>

The loss.

§output: Tensor<B, 2>

The class logits or probabilities. Shape: [batch_size, num_classes].

§targets: Tensor<B, 1, Int>

The ground truth class index for each sample. Shape: [batch_size].
