Expand description

Trait for objective functions in streaming optimization

Required Methods§

Source

fn evaluate( &self, parameters: &ArrayView1<'_, f64>, datapoint: &StreamingDataPoint, ) -> f64

Evaluate the objective function for a single data point

Source

fn gradient( &self, parameters: &ArrayView1<'_, f64>, datapoint: &StreamingDataPoint, ) -> Array1<f64>

Compute the gradient for a single data point

Provided Methods§

Source

fn hessian( self_parameters: &ArrayView1<'_, f64>, _datapoint: &StreamingDataPoint, ) -> Option<Array2<f64>>

Compute the Hessian for a single data point (optional)

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
