چکیده

We investigate the problem of computing the partition function of a probabilistic context-free grammar, and consider a number of applicable methods. Particular attention is devoted to PCFGs that result from the intersection of another PCFG and a finite automaton. We report experiments involving the Wall Street Journal corpus.

Optimizing Teleportation Cost in Multi-Partition Distributed Quantum Circuits

There are many obstacles in quantum circuits implementation with large scales, so distributed quantum systems are appropriate solution for these quantum circuits. Therefore, reducing the number of quantum teleportation leads to improve the cost of implementing a quantum circuit. The minimum number of teleportations can be considered as a measure of the efficiency of distributed quantum systems....

Weighted and Probabilistic Context-Free Grammars Are Equally Expressive

This paper studies the relationship between weighted context-free grammars (WCFGs), where each production is associated with a positive real-valued weight, and probabilistic contextfree grammars (PCFGs), where the weights of the productions associated with a nonterminal are constrained to sum to one. Since the class of WCFGs properly includes the PCFGs, one might expect that WCFGs can describe ...

Variational Bayes via Propositionalization

In this paper, we propose a unified approach to VB (variational Bayes) [1] in symbolicstatistical modeling via propositionalization1. By propositionalization we mean, broadly, expressing and computing probabilistic models such as BNs (Bayesian networks) [2] and PCFGs (probabilistic context free grammars) [3] in terms of propositional logic that considers propositional variables as binary random...

k-Efficient partitions of graphs

A set $S = {u_1,u_2, ldots, u_t}$ of vertices of $G$ is an efficientdominating set if every vertex of $G$ is dominated exactly once by thevertices of $S$. Letting $U_i$ denote the set of vertices dominated by $u_i$%, we note that ${U_1, U_2, ldots U_t}$ is a partition of the vertex setof $G$ and that each $U_i$ contains the vertex $u_i$ and all the vertices atdistance~1 from it in $G$. In this ...

PCFG Learning by Nonterminal Partition Search

pcfg Learning by Partition Search is a general grammatical inference method for constructing, adapting and optimising pcfgs. Given a training corpus of examples from a language, a canonical grammar for the training corpus, and a parsing task, Partition Search pcfg Learning constructs a grammar that maximises performance on the parsing task and minimises grammar size. This paper describes Partit...
