AbstractUnderstanding operator bias in evolutionary computation is important because it is possible for the operator’s biases to work against the intended biases induced by the fitness function. In recent work we showed how developments in GP schema theory can be used to better understand the biases induced by the standard subtree crossover when genetic programming is applied to variable length...

This paper introduces the first formal framework for learning mappings between heterogeneous schemas which is based on logics and probability theory. This task, also called “schema matching”, is a crucial step in integrating heterogeneous collections. As schemas may have different granularities, and as schema attributes do not always match precisely, a general-purpose schema mapping approach re...

In this paper, I argue that the many-worlds theory, even if it is arguably mathematically most straightforward realist reading of quantum formalism, local and deterministic, not universally regarded as best theory because provides a type explanation accepted. Since people disagree about what desiderata satisfactory physical should possess, they also which explanatory schema one look for in lead...

where A is a formula in which Z is not free (but may contain other parameters). Ideally, every formula A should be used in this schema. Unfortunately, it is well known that this would lead to paradoxes. What the various axiomatic set theories do is to replace the general comprehension schema by “safer” versions. Thus most of the axioms of ZF , the most famous axiomatic set theory, are just part...

We introduce the schema model as an alternative computational model representing multiple internal models. The human central nervous system is believed to obtain multiple forward-inverse models. The schema model enables agents to obtain multiple nonlinear forward models incrementally. This model is based on hypothesis testing theory whereas most modular learning methods are based on a Bayesian ...

In this paper we study with a schema-theoretic approach and experiments the search biases produced by GP/GA homologous crossovers when applied to linear, variable-length representations. By specialising the schema theory for homologous crossovers we show that these operators are totally unbiased with respect to string length. Then, we provide a fixed point for the schema evolution equations whe...

Several studies are reviewed that examine differences in moral schema development using techniques intermediate between measuring implicit knowledge (such as with the DeŽ ning Issues Test) and explicit knowledge (such as with the Moral Judgment Interview). Findings include signiŽ cant differences in the comprehension of moral narratives based on age/education and on level of expertise. Also, in...

Abstract Background A central construct in Schema Therapy (ST) is that of a schema mode, describing the current emotional-cognitive-behavioral state. Initially, 10 modes were described. Over time, with world-wide increasing and broader application ST to various disorders, additional identified, mainly based on clinical impressions. Thus, need for new, theoretically based, cross-cultural taxonom...

This paper introduces a framework for relational schema navigation via a Web-based browser application that uses Formal Concept Analysis as the metaphor for analysis and interaction. Formal Concept Analysis is a rich framework for data analysis based on applied lattice and order theory. The application we develop, D-SIFT, is intended to provide users untrained in Formal Concept Analysis with pr...
