Improving estimation of distribution genetic programming with novelty initialization
2021
Estimation of distribution genetic programming (EDA-GP) replaces the standard variation operations of genetic programming (GP) by learning and sampling from a probabilistic model. Unfortunately, many EDA-GP approaches suffer from a rapidly decreasing population diversity which often leads to premature convergence. However, novelty search, an approach that searches for novel solutions to cover sparse areas of the search space, can be used for generating diverse initial populations. In this work, we propose novelty initialization and test this new method on a generalization of the royal tree problem and compare its performance to ramped half-and-half (RHH) using a recent EDA-GP approach. We f…
Innovation capabilities: What are their characteristics and how can they be conceptualized?
2017
Purpose – It has been argued that firms may utilize their resources and capabilities through the development of innovations in the form of new products, services or processes, and empirical research has confirmed that there is a positive relationship between the implementation of innovation activities and future performance of firms. Some firms prove to be better at reproducing innovation success than other firms, and the capacity to do so can be framed as an innovation capability. However, the term innovation capability is ambiguously treated in extant literature. There exist several different definitions of the concept and the distinction between innovation capabilities and other types of…
Particularities of the European Consumer’s Behavior in Online Environments
2016
Abstract Although it is no longer a novelty that the Internet has now become “fashionable”, being a means of informing, socializing and trading, which is being increasingly used by the general public, it is now imperative to study the implications of its use both on the consumer, including all the roles that it can take (initiating, financing, influencing, decision making, actual consumption of goods and services) and on the marketer, who is forced to consider the Internet as a marketing tool that can be used as a lever to generate positive reactions from the consumers. Against this background, the orientation of the individuals towards the online environment, defined by specialized literat…
The New Gnosis and the Denial of Ontological Differences
2021
The current transhumanist or posthumanist movements continue the thesis of the old gnosis devaluing the creation like something imperfect. Its novelty is to believe in the possibility of overcoming the creation thanks to technology (biotechnology and bionics). The ideology of gender partly anticipates this way of thinking by devaluing the somatic difference between male and female. This denial of the differences then applies to those existing between the human and the non-human (on one side the primates, and on the other the computer). Posthumanism and transhumanism believe that technology will not only overcome the ontological differences, which form the human, but also the so-called extre…
The Diffusion of Humans and Cultures in the Course of the Spread of Farming
2017
The spread of farming into Europe some 9000–5000 years ago involved not only the advent of new plants and animals, but also of people, tools, technologies, and knowledge. While they all can be assumed to follow Fickian diffusion gradients, the mechanisms of spread can be quite different: when people migrate, there is mass balance in the number of people, but not in the knowledge and technologies brought along. Tools, plants and animals could also travel by trade, knowledge and technology by communication; there might even be local resistance to adoption of novelty. This chapter discusses these different diffusion mechanisms in the context of numerical trait- and agent-based socio-environmen…
An unsupervised Learning Algorithm for Fatigue Crack Detection in Waveguides
2009
Ultrasonic guided waves (UGWs) are a useful tool in structural health monitoring (SHM) applications that can benefit from built-in transduction, moderately large inspection ranges, and high sensitivity to small flaws. This paper describes an SHM method based on UGWs and outlier analysis devoted to the detection and quantification of fatigue cracks in structural waveguides. The method combines the advantages of UGWs with the outcomes of the discrete wavelet transform (DWT) to extract defect-sensitive features aimed at performing a multivariate diagnosis of damage. In particular, the DWT is exploited to generate a set of relevant wavelet coefficients to construct a uni-dimensional or multi-di…
Control of Production-Distribution Systems under Discrete Disturbances and Control Actions
2011
This paper deals with the robust control and optimization of production-distribution systems. The model used in our problem formulation is a general network flow model that describes production, logistics, and transportation applications. The novelty in our formulation is in the discrete nature of the control and disturbance inputs. We highlight three main contributions: First, we derive a necessary and sufficient condition for the existence of robustly control invariant hyperboxes. Second, we show that a stricter version of the same condition is sufficient for global convergence to an invariant set. Third, for the scalar case, we show that these results parallel existing results in the set…
Influence of the Novelty-Seeking Endophenotype on the Rewarding Effects of Psychostimulant Drugs in Animal Models
2015
Novelty seeking (NS), defined as a tendency to pursue novel and intense emotional sensations and experiences, is one of the most relevant individual factors predicting drug use among humans. High novelty seeking (HNS) individuals present an increased risk of drug use compared to low novelty seekers. The NS endophenotype may explain some of the differences observed among individuals exposed to drugs of abuse in adolescence. However, there is little research about the particular response of adolescents to drugs of abuse in function of this endophenotype, and the data that do exist are inconclusive. The present work reviews the literature regarding the influence of NS on psychostimulant reward…
Electrophysiological evidence for change detection in speech sound patterns by anesthetized rats
2014
Human infants are able to detect changes in grammatical rules in a speech sound stream. Here, we tested whether rats have a comparable ability by using an electrophysiological measure that has been shown to reflect higher order auditory cognition even before it becomes manifested in behavioral level. Urethane-anesthetized rats were presented with a stream of sequences consisting of three pseudowords carried out at a fast pace. Frequently presented “standard” sequences had 16 variants which all had the same structure. They were occasionally replaced by acoustically novel “deviant” sequences of two different types: structurally consistent and inconsistent sequences. Two stimulus conditions we…
Development of capabilities from the innovation of the perspective of poverty and disability
2017
Abstract Poverty is a reality that is present to a greater or lesser extent in all regions of the world. Disability, like poverty, is also a reality in the society in which we live. Disability is not only a reality, but an inescapable truth, as at some point in life all people will be vulnerable and will exhibit some form of disability. When combined, poverty and disability immerse a person in more serious circumstances. Within the concept of poverty, disability means greater poverty. Based on a correct conceptualization of what poverty and disability are, this paper aims at proposing an innovative model of accompaniment, one which starts from a complete and multidimensional vision of reali…
