Trait linfa::metrics::BinaryClassification

pub trait BinaryClassification<T> {
    fn roc(&self, y: T) -> Result<ReceiverOperatingCharacteristic>;
    fn log_loss(&self, y: T) -> Result<f32>;
}

Classification for binary-labels

This contains Receiver-Operating-Characterstics curves and log loss as those only work for binary classification tasks.

Required Methods

fn roc(&self, y: T) -> Result<ReceiverOperatingCharacteristic>

fn log_loss(&self, y: T) -> Result<f32>
