A Clustering and Demotion Based Algorithm for Inductive Learning of Default Theories [article]

Huaduo Wang, Farhad Shakerin, Gopal Gupta
2021 arXiv   pre-print
We present a clustering- and demotion-based algorithm called Kmeans-FOLD to induce nonmonotonic logic programs from positive and negative examples.  ...  Our experiments on the UCI dataset show that a combination of K-Means clustering and our demotion strategy produces significant improvement for datasets with more than one cluster of positive examples.  ...  (v) extending our algorithm for multi-relational input datasets. Note that our work reported here that makes use of clustering and demotion to improve the FOLD algorithm is just the beginning.  ...

A Maximum Entropy Model of Phonotactics and Phonotactic Learning

Bruce Hayes, Colin Wilson
2008 Linguistic Inquiry  
The study of phonotactics is a central topic in phonology. We propose a theory of phonotactic grammars and a learning algorithm that constructs such grammars from positive evidence.  ...  We apply the model in a variety of learning simulations, showing that the learned grammars capture the distributional generalizations of these languages and accurately predict the findings of a phonotactic  ...  For OT, the Constraint Demotion algorithm family of Tesar and Smolensky (1998, 2000) satisfies the first of these criteria in a sense, as it provably converges for the case of consistent input-output  ...

Participant association and emergent curriculum in a MOOC: can the community be the curriculum?

Frances Bell, Jenny Mackness, Mariana Funes
2016 Research in Learning Technology  
We investigated how participants associated with each other and developed community in a Massive Open Online Course (MOOC) about Rhizomatic Learning (Rhizo14).  ...  Our combination of thematic analysis of qualitative survey data with analysis of participant observation, activity data, archives and visualisation of SNS data enabled us to reach a deeper understanding  ...  Acknowledgements We would like to thank Rhizo14 participants especially those who gave their time to complete the survey and answer our questions.  ...

An empirical study of on-line models for relational data streams

Ashwin Srinivasan, Michael Bain
2016 Machine Learning  
In this paper, we investigate the adoption of a stream-based on-line learning approach to relational data.  ...  To date, Inductive Logic Programming (ILP) systems have largely assumed that all data needed for learning have been provided at the onset of model construction.  ...  Some part of this work was supported by a Ramanujan Fellowship from the Department of Science and Technology, Government of India.  ...

Loanword accentuation in Yanbian Korean: a weighted-constraints analysis

Chiyuki Ito
2013 Natural language & linguistic theory  
These markedness constraints are weighted by the learning algorithm so that the weight hierarchy can achieve a more or less "faithful adaptation" of the source language.  ...  Through a learning process, the original faithfulness constraints to the source language are demoted below relevant markedness constraints.  ...  I also thank Adam Albright for sharing with me the program for the learning algorithm used in section 4.1, and Shigeto Kawahara for advice about statistics.  ...

Stochastic phonological knowledge: the case of Hungarian vowel harmony

Bruce Hayes, Zsuzsa Cziráky Londe
2006 Phonology  
We model the speakers' knowledge and intuitions with a grammar constructed under the dual listing/generation model of Zuraw (2000) , then show how the constraint rankings of this grammar can be learned  ...  by algorithm. * * We would like to thank for helpful advice.  ...  Both of our algorithms, Low Faithfulness Constraint Demotion and Biased Constraint Demotion, require a set of losing candidates for learning (the rankings are learned by comparing these losers with winning  ...

The Actuation Problem in Optimality Theory [chapter]

Ricardo Bermúdez-Otero, Richard M. Hogg
2003 Studies in Natural Language and Linguistic Theory  
We show that, whereas OT predicts this state of affairs, rule-based theories cannot account for the facts without imposing contradictory demands on acquisition theory.  ...  It is therefore suggested that, as a theory of grammar, OT will play a secondary role in accounts of phonologization.  ...  These criteria are compatible with noninnatist approaches such as Hayes's (1999) theory of inductive grounding, where the learner is equipped with an algorithm for constraint discovery that guarantees  ...

Cognitive resource depletion in religious interactions

Uffe Schjoedt, Jesper Sørensen, Kristoffer Laigaard Nielbo, Dimitris Xygalatas, Panagiotis Mitkidis, Joseph Bulbulia
2013 Religion, Brain & Behavior  
We explore the cognitive effects of three common features of religious interactions: (1) demand for the expressive suppression of emotion; (2) exposure to goaldemoted and causally opaque actions; and (  ...  Using a cognitive resource model of executive function, we argue that these three features affect the executive system in ways that limit the capacity for individual processing of religious events.  ...  Many of our actions and choices are the result of subconscious algorithms and associational processing.  ...
