Evolutionary Robotics : Coping with Environmental Change { Category : Evolutionary Robotics ( ER ) {
In this paper an evolutionary method consisting of encoding a set of local adaptation rules that synapses obey while a robot freely moves in the environment is compared to standard evolution of xed-weight control networks. The results show that evolutionary adaptive controllers can adapt on-line without additional evolutionary training to strong environmental changes where instead the performan...
متن کاملEvolutionary model of the concepts of ‘color chip’ and ‘color category’ in Evolutionary models of color categorization based on discrimination
Komarova et al. (2007) showed that a color naming system could be evolved by combining perceptual discrimination, basic pragmatic constraints on communication, and simple learning rules. Their system relied on a fixed number of color chips and of color categories. Here, I construct an evolutionary game theory model where the equivalent concept of the former and the number of the latter are emer...
متن کاملColor category influences heterogeneous visual search for color.
Many previous studies have revealed chromatic characteristics of visual search using relatively simple stimuli. They suggested that color difference between a target and distractors was a crucial factor. However, it may not be applicable to natural environments that contain numerous colors. This study demonstrates the existence of a color-category effect on heterochromatic visual search. Color ...
متن کاملBayesian Approaches to Color Category Learning
One of the challenges that children face as they acquire a language is discovering how words are used to refer to different colors. While human languages demonstrate variation in how they partition the space of colors, there are also clear regularities in the kinds of systems of color categories that are used [1]. This raises two important questions: How might color categories be learned? And h...
متن کاملConfidence Judgments on Color Category Best Exemplars
Although basic color terms and basic color appearances have been shown to produce higher confidence ratings in a variety of naming and judgment tasks, our findings suggest that when different ethnolinguistic cultures are compared, higher confidence is not strictly linked to the basic foci of Berlin and Kay nor the centroid samples identified by Boynton and colleagues. This raises important ques...
