class navlie.batch.losses.LossFunction

Bases: ABC

Abstract base class for any loss function.

abstract loss(e: float)

The loss function defines the cost \(\rho(e)\), where \(e\) is an error term and is often a function of the design variable.

abstract weight(e: float)

The weight that depends on the current value of the error. This is used to reweight our original nonlinear least squares problem.
