Fast Learning from Strings of 2-Letter Rigid Grammars
[chapter]
2002
Lecture Notes in Computer Science
In the search for classes which can be learned efficiently from strings, we study the class of 2-letter rigid grammars, which is the class of classical categorial grammars with an alphabet of two letters ...
The (non-trivial) structure of this class of grammars is studied and it is shown that grammars in this class can be learned very efficiently. ...
Learning 2-Letter Rigid Grammars Since the languages of loopless grammars consist of only one string, they are not interesting in terms of learnability. ...

Learning Lambek Grammars from Proof Frames
[chapter]
2014
Lecture Notes in Computer Science
These grammars were shown to be unlearnable from strings by Foret and Le Nir. ...
After a short reminder on grammatical inferenceà la Gold, we provide an algorithm that learns Lambek grammars with product from proof frames and we prove its convergence. ...
Ideally, one would like to learn directly from strings, but in the case of Lambek grammars it has been shown to be impossible in [16] . ...

Learning Recursive Automata from Positive Examples
2006
Revue d'intelligence artificielle : Revue des Sciences et Technologies de l'Information
Finally, new learnable subclasses of categorial grammars are defined, for which learning from strings is nearly not more expensive than from structures. RÉSUMÉ. ...
In this theoretical paper, we compare the "classical" learning techniques used to infer regular grammars from positive examples with the ones used to infer categorial grammars. ...
According to Property 6, such a string is obtained by following a path starting from the state x 3 /x 2 and reaching the final state F . The letter b labels such a direct path. ...

Implicit assumptions about implicit learning
1994
Behavioral and Brain Sciences
We examine the evidence for implicit learning derived from subliminal learning, conditioning, artificial grammar learning, instrumental learning, and reaction times in sequence learning. ...
The assumption that learning in some of these tasks (e.g., artificial grammar learning) is predominantly based on rule abstraction is questionable. ...

Spreadsheet Structure Discovery with Logic Programming
2008
arXiv
pre-print
We are implementing structure discovery tools in the logic-programming language Prolog for our spreadsheet analysis program Model Master, by writing grammars for spreadsheet structures. ...
Our term "structure discovery" denotes the recovery of structure, such as the grouping of cells, that was intended by a spreadsheet's author but is not explicit in the spreadsheet. ...
So we have symbols (the letters) that stand for themselves, but also symbols that stand for sets of strings. ...

The language faculty that wasn't: a usage-based account of natural language recursion
2015
Frontiers in Psychology
Evidence from genetics, comparative work on non-human primates, and cognitive neuroscience suggests that humans have evolved complex sequence learning skills, which were subsequently pressed into service ...
We then focus on recursion as a detailed case study, arguing that our ability to process recursive structure does not rely on recursion as a property of the grammar, but instead emerges gradually by piggybacking ...
The recalled 15 strings were then recoded in terms of their specific letters to avoid trivial biases such as the location of letters on the computer keyboard and the presence of potential acronyms (e.g ...
