On a property of probabilistic context-free grammars [PDF]
It is proved that for a probabilistic context-free language L(G), the population density of a character (terminal symbol) is equal to its relative density in the words of a sample S from L(G) whenever the production probabilities of the grammar G are ...

Inducing Probabilistic Grammars by Bayesian Model Merging [PDF]
We describe a framework for inducing probabilistic grammars from corpora of positive samples. First, samples are {\em incorporated} by adding ad-hoc rules to a working grammar; subsequently, elements of the model (such as states or nonterminals) are {\em

A Probabilistic Grammar of Graphics
Visualizations depicting probabilities and uncertainty are used everywhere from medical risk communication to machine learning, yet these probabilistic visualizations are difficult to specify, prone to error, and their designs are cumbersome to explore.

Relating probabilistic grammars and automata [PDF]
Both probabilistic context-free grammars (PCFGs) and shift-reduce probabilistic pushdown automata (PPDAs) have been used for language modeling and maximum likelihood parsing. We investigate the precise relationship between these two formalisms, showing that, while they define the same classes of probabilistic languages, they appear to impose different ...

Probabilistic retrieval with a visual grammar [PDF]
We describe a system for content-based retrieval and classification of multispectral images. Our system models images on pixel, region and scene levels. To reduce the gap between low-level features and highlevel user semantics, and to support complex query scenarios that consist of many regions with different feature characteristics, we propose a ...

Bayesian validation of grammar productions for the language of thought. [PDF]
Probabilistic proposals of Language of Thoughts (LoTs) can explain learning across different domains as statistical inference over a compositionally structured hypothesis space. While frameworks may differ on how a LoT may be implemented computationally,

LPG–PCFG: An Improved Probabilistic Context- Free Grammar to Hit Low-Probability Passwords
With the development of the Internet, information security has attracted more attention. Identity authentication based on password authentication is the first line of defense; however, the password-generation model is widely used in offline password ...
