Competitive Kaisers

Digitalisierung in Lehre und Lernen: des Kaisers neue Kleider?!

In den vergangenen Jahren konnten zahlreiche Initiativen und Konzepte für die Erprobung digital unterstützten Lehren und Lernens wahrgenommen werden und Begriffe wie E-Learning oder Blended Learning waren in aller Munde. Gegenwärtig redet man an vielen Punkten von Digitalisierung, weshalb man folgende Fragen stellen kann: Ist Digitalisierung das neue Kleid des E-Learnings? Ist E-Learning „tot“?...

6 Competitive Networks and Competitive Learning

Competitive neural networks belong to a class of recurrent networks, and-they are based on algorithms of unsupervised learning, such as the competitive algorithm explained in this section. In competitive learning, the output neurons of a neural network compete among themselves to become active (to be "fired"). Whereas in multiplayer perceptrons several output neurons may be active simultaneousl...

Complex competitive systems and competitive thermodynamics.

This publication reviews the framework of abstract competition, which is aimed at studying complex systems with competition in their generic form. Although the concept of abstract competition has been derived from a specific field--modelling of mixing in turbulent reacting flows--this concept is, generally, not attached to a specific phenomenon or application. Two classes of competition rules, ...

Competitive Framing∗

I present a simple framework for modeling two-firm market competition, where each firm chooses a market alternative as well as a costless “marketing message”. Consumers follow a frame-dependent choice function, where the frame is a probabilistic function of the firms’ marketing messages. This framework embeds several recent models in the literature on markets with boundedly rational consumers. ...
