Function Documentation

std::unique_ptr< loss_function > meta::classify::loss::make_loss_function

(

const std::string &

identifier

)

Convenience method for making a loss function using the factory.

Parameters

identifier

the identifier for the loss function to be created

Returns

a unique_ptr to the loss function created

template<class Loss >

std::unique_ptr<loss_function> meta::classify::loss::make_loss_function

(

)

Factory method for creating a loss function.

Returns

a unique_ptr to a loss_function (of derived type Loss)

template<class Loss >

void meta::classify::loss::register_loss_function

(

)

Registration method for loss functions.

Clients should use this method to register any new loss functions they write.
