Member Function Documentation

void IMP::isd::Weight::add_to_weight_derivative ( int  i,
Float  dwi,
const DerivativeAccumulator da 
)

Add to derivative wrt ith weight.

void IMP::isd::Weight::add_to_weights_derivatives ( const algebra::VectorKD dw,
const DerivativeAccumulator da 
)

Add to derivatives wrt all weights.

void IMP::isd::Weight::add_weight ( Float  wi = 0)

Extend the weight vector by one element.

This should only be called during set-up and cannot be called for an optimized Weight.

void IMP::isd::Weight::add_weight_lazy ( Float  wi = 0)

Extend the weight vector by one element lazily.

This should only be called during set-up and cannot be called for an optimized Weight. This version delays enforcing the simplex constraint until Model::update().

Int IMP::isd::Weight::get_number_of_weights ( ) const

Get number of weights.

static IntKey IMP::isd::Weight::get_number_of_weights_key ( )
static

Get number of weights key.

algebra::UnitSimplexKD IMP::isd::Weight::get_unit_simplex ( ) const

Get unit simplex on which weight vector lies.

Float IMP::isd::Weight::get_weight ( int  i) const

Get the ith weight.

Float IMP::isd::Weight::get_weight_derivative ( int  i) const

Get derivative wrt ith weight.

static FloatKey IMP::isd::Weight::get_weight_key ( int  i)

algebra::VectorKD IMP::isd::Weight::get_weights_derivatives ( ) const

Get derivatives wrt all weights.

void IMP::isd::Weight::set_number_of_weights ( Int  nweights)

Set number of weights.

This should only be called during set-up and cannot be called for an optimized Weight. New weights are initialized to 0.

void IMP::isd::Weight::set_number_of_weights_lazy ( Int  nweights)

Set number of weights lazily.

This should only be called during set-up and cannot be called for an optimized Weight. New weights are initialized to 0. This version delays enforcing the simplex constraint until Model::update().

void IMP::isd::Weight::set_weight_lazy ( int  i,
Float  wi 
)

Set the ith weight lazily.

Delay enforcing the simplex constraint until Model::update().
