A Unifying Model for Representing Time-Varying Graphs [PDF]

open access: yes, 2014
Graph-based models form a fundamental aspect of data representation in Data Sciences and play a key role in modeling complex networked systems. In particular, recently there is an ever-increasing interest in modeling dynamic complex networks, i.e ...

Examining a Factor Structure of Home Math Activities by Math Subdomain With Associations to Children’s Math Skills

open access: yesJournal of Numerical Cognition
Evidence of positive associations between the frequency of home math activities and preschool children’s math skills is mixed, and the operationalization of home math activities varies across studies.

Transforming N-ary relationships to database schemas: an old and forgotten problem [PDF]

open access: yes, 2002
The N-ary relationships, have been traditionally a source of confusion and still are. One important source of confusion is that the term cardinality in a relationship has several interpretations, two of them being very popular.

Testing and Debugging Techniques for Answer Set Solver Development

open access: yes, 2010
This paper develops automated testing and debugging techniques for answer set solver development. We describe a flexible grammar-based black-box ASP fuzz testing tool which is able to reveal various defects such as unsound and incomplete behavior, i.e ...

Solving Set Constraint Satisfaction Problems using ROBDDs

open access: yes, 2011
In this paper we present a new approach to modeling finite set domain constraint problems using Reduced Ordered Binary Decision Diagrams (ROBDDs). We show that it is possible to construct an efficient set domain propagator which compactly represents many

Algorithm Engineering in Robust Optimization

open access: yes, 2015
Robust optimization is a young and emerging field of research having received a considerable increase of interest over the last decade. In this paper, we argue that the the algorithm engineering methodology fits very well to the field of robust ...

Weakly-supervised Dictionary Learning

open access: yes, 2018
We present a probabilistic modeling and inference framework for discriminative analysis dictionary learning under a weak supervision setting. Dictionary learning approaches have been widely used for tasks such as low-level signal denoising and ...

Network formation by reinforcement learning: the long and medium run

open access: yes, 2003
We investigate a simple stochastic model of social network formation by the process of reinforcement learning with discounting of the past. In the limit, for any value of the discounting parameter, small, stable cliques are formed.
