Class TTable_monolithic_IFAs

java.lang.Object
  edu.umd.hooka.ttables.TTable
      edu.umd.hooka.ttables.TTable_monolithic_IFAs

All Implemented Interfaces:

Cloneable

public class TTable_monolithic_IFAs
extends TTable
implements Cloneable

Data structure that stores translation probabilities p(f|e) or counts c(f,e). The set of values (*,e) associated with a particular e are stored adjacent to one another in an array. For a given f in (f,e) the location of the f is found using a binary search. Layout: http://www.umiacs.umd.edu/~redpony/ttable-structure.png
