AbstractedPCFG(non_terminals, terminals, ...)
|
An AbstractedPCFG defines an RBN that has only one non-terminal and one terminal variable, both being discrete with a cardinality corresponding to the number of non-terminal and terminal symbols of the PCFG, respectively. |
DiscreteBinaryNonTerminalTransition(weights)
|
A binary non-terminal transition for discrete non-terminal variables. |
DiscreteCell(variable, weights, transitions)
|
A cell for a discrete variable, where the structural distribution may depend on the variable's value |
DiscreteNonTermVar(cardinality[, chart_type])
|
A discrete non-terminal variable with cardinality cardinality. |
DiscretePrior(struc_weights, prior_weights)
|
A prior distribution over discrete non-terminal variables. |
