using Schema Theory to explore interactions of multiple operators
Genetic and Evolutionary Computation Conference, 2002Co-Authors: Nicholas Freitag Mcphee, Riccardo PoliAbstract:In the last two years the Schema Theory for Genetic Programming (GP) has been applied to the problem of understanding the length biases of a variety of crossover and mutation operators on variable length linear structures. In these initial papers, operators were studied in isolation. In practice, however, they are typically used in various combinations, and in this paper we present the first Schema Theory analysis of the complex interactions of multiple operators. In particular, we apply the Schema Theory to the use of standard subtree crossover, full mutation, and grow mutation (in varying proportions) to variable length linear structures in the one-then-zeros problem. We then show how the results can be used to guide choices about the relative proportion of these operators in order to achieve certain structural goals during a run.

Lessons from the GP Schema Theory
Foundations of Genetic Programming, 2002Co-Authors: William B. Langdon, Riccardo PoliAbstract:This chapter considers different ways in which we can use the Schema Theory described in the previous chapters to better understand the dynamics of genetic programming populations. We will also illustrate the possible uses of the Schema Theory to clarify concepts such as effective fitness (next section), biases in GP (Section 6.2), building blocks (Section 6.3), problem hardness and deception (Section 6.5). We also discuss new ideas inspired by Schema theories (Section 6.4).

Schema Theory and English Listening Comprehension
Journal of Dalian Nationalities University, 2006Co-Authors: Lian JieAbstract:Based on the Schema Theory,this paper studies the effect of listeners' Schema knowledge on their English listening comprehension and the illuminating effect of Schema Theory on the teaching of English listening comprehension with a view to improving students' listening ability.

Schema Theory: Very promising
Behavioral and Brain Sciences, 2000Co-Authors: Alexander GrunewaldAbstract:A direct equivalence between neural function and neural structure does not provide a fruitful approach to understanding brain functioning. Arbib et al. describe a new and powerful approach to circumvent this problem, which they call Schema Theory. However, in examples they fall prey to the tradition of finding such equivalences, not doing Schema Theory justice.

Application of Schema Theory to the Teaching of English Listening
Journal of Guangdong Radio and Tv University, 2005Co-Authors: Luo Chun-pingAbstract:On the basis of a analysis of relationship between Schema Theory and English listening,this paper is concerned with the application of Schema Theory to the teaching of English listening,aiming to enhance the teaching of English listening in Theory and practice.
