© 2015 Elsevier B.V. This study provides a new, more comprehensive measurement of technological novelty. Integrating insights from the existing economics and management literature, we characterize inventions ex ante along two dimensions of technological novelty: Novelty in Recombination and Novelty in Knowledge Origins. For the latter dimension we distinguish between Novel Technological and Novel Scientific Origins. For each dimension we propose ...

This PhD dissertation investigates the sources of novel technologies and of their value. Novel technologies satisfy human needs in unprecedented ways (often involving new principles, applications and/or combinations of components). They hold great promise but also high risk; the vast majority are worthless, while a select few have a rather disproportionate value and impact on subsequent technological development. Given their substantial—though ...

One-class classification is the standard procedure for novelty detection. Novelty detection aims to identify observations that deviate from a determined normal behaviour. Only instances of one class are known, whereas so called novelties are unlabelled. Traditional novelty detection applies methods from the field of outlier detection. These standard one-class classification approaches have limited performance in many real business cases. The ...

© Springer Nature Switzerland AG 2019. The purpose of this paper is to develop a methodology that utilises the order-frequency spectral coherence to detect novel (i.e. unobserved) second-order cyclostationary components. In the novelty detection methodology, a probabilistic model of the healthy data is utilised to detect, localise and trend novelties in the form of damage that manifest as second-order cyclostationary components in vibration ...

Background: The long-standing observation that the novelty-seeking personality trait is a predictor of drug use and other reinforcable risky behaviors raises the question as to how novelty and reward processing functionally interact in mesolimbic dopaminergic circuitry and how this interaction is modulated by the novelty-seeking personality trait. Methods: Functional magnetic resonance imaging (fMRI) hemodynamic responses to novelty and reward ...
