Constructing and validating readability models: the method of integrating multilevel linguistic features with machine learning.

Behavior research methods Jun 1, 2015
Multilevel linguistic features have been proposed for discourse analysis, but there have been few applications of multilevel linguistic features to readability models and also few validations of such models. Most traditional readability formulae are ...

The entropic basis of collective behaviour.

Journal of the Royal Society, Interface May 6, 2015
We identify a unique viewpoint on the collective behaviour of intelligent agents. We first develop a highly general abstract model for the possible future lives these agents may encounter as a result of their decisions. In the context of these possib...

Semi-Supervised Affinity Propagation with Soft Instance-Level Constraints.

IEEE transactions on pattern analysis and machine intelligence May 1, 2015
Soft-constraint semi-supervised affinity propagation (SCSSAP) adds supervision to the affinity propagation (AP) clustering algorithm without strictly enforcing instance-level constraints. Constraint violations lead to an adjustment of the AP similari...
