Member Function Documentation

virtual double semantics::Marginal_cell_base::backoff_probability ( ) const

pure virtual

prob of this outcome conditioned on starting a new table

corresponds to q(x,H) in the writeup

Implemented in semantics::Marginal_cell< T, N >, and semantics::Prior_cell< T >.

virtual Context_ptr semantics::Marginal_cell_base::context ( ) const

pure virtual

get ptr to conditioning context cell

Implemented in semantics::Marginal_cell< T, N >, and semantics::Prior_cell< T >.

virtual void semantics::Marginal_cell_base::decrement ( const size_t &  table_code )

pure virtual

increment the count associated with a particular table

Implemented in semantics::Marginal_cell< T, N >, and semantics::Prior_cell< T >.

virtual void semantics::Marginal_cell_base::increment ( const size_t &  table_code )

pure virtual

increment the count associated with a particular table

Implemented in semantics::Marginal_cell< T, N >, and semantics::Prior_cell< T >.

virtual Self_ptr semantics::Marginal_cell_base::margin ( ) const

pure virtual

get smoothed marginal cell ptr

Implemented in semantics::Marginal_cell< T, N >, and semantics::Prior_cell< T >.

virtual double semantics::Marginal_cell_base::predictive_probability ( ) const

pure virtual

predictive probability of this outcome in this context

corresponds to p(x|beta(H)) in the writeup, but is not normalized. normalization must occur later when comparing

Implemented in semantics::Marginal_cell< T, N >, and semantics::Prior_cell< T >.

virtual size_t semantics::Marginal_cell_base::sample_table_assignment ( )

pure virtual

sample from the conditional predictive distribution of table assignment

Implemented in semantics::Marginal_cell< T, N >, and semantics::Prior_cell< T >.

virtual double semantics::Marginal_cell_base::smoothed_probability ( )

pure virtual

get smoothed probability estimate

Implemented in semantics::Marginal_cell< T, N >, and semantics::Prior_cell< T >.
