Controlling bloating using depth constraint crossover

Geng Li;Xiao-Jun Zeng

2010 UK Workshop on Computational Intelligence (UKCI)

Year: 2010 | Conference Paper |

HTML

We develop a simple modification of crossover called depth constraint crossover to control bloating. As the name suggests, depth constraint crossover adds a depth constraint on the selection of crossover point. This method is motivated by the analysis of removal bias bloating theory. In this paper, we quantitatively define removal bias as the depth difference between swapped subtrees in crossover....Show More

Year: 2008 | Conference Paper |

Cited by: Papers (4)

This paper proposes an incremental construction learning algorithm for identification of T-S Fuzzy Systems. The mechanism of the algorithm is that it is an error-reducing driven learning method. Beginning with a simplest T-S fuzzy system, the algorithm develops the system structure by adding more fuzzy terms and rules to reduce the model errors in a ‘greedy’ way. The main features of the proposed ...Show More

Learning for Hierarchical Fuzzy Systems Based on the Gradient-Descent Method

Di Wang;Xiao-Jun Zeng;J.A. Keane

2006 IEEE International Conference on Fuzzy Systems

Year: 2006 | Conference Paper |

Cited by: Papers (5)

HTML

Standard fuzzy systems suffer the "curse of dimensionality" which has become the bottleneck when applying fuzzy systems to solve complex and high dimensional application problems. This curse of dimensionality results in a larger number of fuzzy rules which reduces the transparency of fuzzy systems. Furthermore too many rules also reduce the generalization capability of fuzzy systems. Hierarchical ...Show More

The author comments on the paper by Singh and Zeng (see ibid., vol.2, no.2, p.162-76, 1994). He states that every bounded function f: R/spl rarr/R has an exact representation as an additive fuzzy system. If f is not constant, one fuzzy set and two rules define the system. Otherwise, a single rule suffices. This result shows that the approximation properties of one-input fuzzy systems derive solely...Show More
