Financial Forecasting Using Genetic Algorithms - Mahfoud, Mani (1996) (6 citations) (Correct)
.... Valenzuela Rendn, 1989) Fitness sharing works by reducing the fitnesses of similar population elements. Crowding (De Jong, 1975; Mahfoud, 1992, 1994, 1995a) is another type of niching method that has also been applied to classification (Booker, 1982; Goldberg, 1983; Holland Reitman, 1978; Sedbrook et al. 1991; Stadnyk, 1987) Crowding forces newly generated population elements to replace older elements that are similar. Sequential niching (Beasley et al. 1993) is a third approach, implemented by Sikora and Shaw (1994) in their genetic classification system. Sequential niching repeatedly runs a ....

Differential Negative Reinforcement Improves Classifier System.. - Holmes (Correct)
....2. The effect of a single erroneous decision on false negative and false positive rates. For purposes of illustration, his plot assumes a sample size of 100. The ratio of false positives to false negatives has been used as an element in a reward function in a classifier system. Previous work (Sedbrook, Wright, and Wright 1991) put the optimal ratio of 8:1, but did not examine the effect of adjusting the ratio on data at different prevalences. In a LCS using payoff penalty reinforcement, the penalty could be adjusted to bias the negative reinforcement an inaccurate classifier receives. 4.0 Focus of this investigation ....
