Is Anything Ever New? Considering Emergence
نویسنده
چکیده
This brief essay reviews an approach to defining and then detecting the emergence of complexity in nonlinear processes. It is, in fact, a synopsis of Reference [1] that leaves out the technical details in an attempt to clarify the motivations behind the approach. The central puzzle addressed is how we as scientists — or, for that matter, how adaptive agents evolving in populations — ever “discover” anything new in our worlds, when it appears that all we can describe is expressed in the language of our current understanding. One resolution — hierarchical machine reconstruction — is proposed. Along the way, complexity metrics for detecting structure and quantifying emergence, along with an analysis of the constraints on the dynamics of innovation, are outlined. The approach turns on a synthesis of tools from dynamical systems, computation, and inductive inference.

Security Constrained Unit Commitment in the Simultaneous Presence of Demand Response Sources and Electric Vehicles
Due to the ever-growing load, especially peak load, the increase in the capacity of plants is inevitable for the response to this growth. Peak load causes increases in customer costs and vast investments in generating and transmission parts. Therefore, restructuring in the electrical industry, competition in the electrical market and Demand Response Programs (DRPs) are of special importance in ...

Traditionally, conventional generation unit was used to provide ancillary services e.g. reactive power support, and spinning reserve. Nonetheless, with the emergence of highly penetrated distributed energy resources (DERs) systems and considering how beneficial they can be; it appears reasonable to use them as reactive power providers. Therefore, this paper introduces a new procedure for DERs t...

متن کاملAesthetics of Everyday Life
Aesthetics of everyday life is one of the branches of aesthetic knowledge. Until the 20th century, classical aesthetics focused on the subject of visual arts and paid less attention to the formation of fine arts in the context of human and nature’s daily life experience. During the last few decades, a movement emerged that, by avoiding that one-sided art-oriented approach, tried to create a clo...
متن کاملWhy AIED Needs Marriage Counselling by Cognitive Science (to Live Happily Ever After)
In this position paper, I reflect upon the question “Should AI stay married to Ed?”, specifically referring to how research in AI and Education should cross-fertilize to define AIED as an independent practice, beyond its composite fields. In my view, a mix of approaches, inspired by cognitive science, should serve to formulate characteristic research questions for the AIED community. Such quest...
