Detailed Description

Analytic quotient (AQ).

Analytic quotient (AQ) operator systematically yields lower mean squared errors over a range of regression tasks, due principally to removing the discontinuities or singularities that can often result from using either protected or unprotected division. Further, the AQ operator is differentiable.

Constructor & Destructor Documentation

◆ aq()

vita::real::aq::aq ( const cvect & c = {0} )

inlineexplicit

Definition at line 192 of file real.h.

Member Function Documentation

◆ display()

std::string vita::real::aq::display ( format ) const

inlinefinalvirtual

Returns: the name of the function

Warning: Specific functions have to specialize this method to support different output formats.

Reimplemented from vita::function.

Definition at line 195 of file real.h.

◆ eval()

value_t vita::real::aq::eval ( symbol_params & ) const

inlinefinalvirtual

Calculates the value of / performs the action associated with the symbol (it's implementation specific).

Implements vita::symbol.
