Tech, Data, Travel and Life. Love travelling with my camper van and writing about mentioned topics.

Die Tage werden kürzer, die Temperaturen sinken und die Blätter an den Weinreben und Bäumen färben sich von grün in ein Meer aus Gelb- und Rottönen. Das letzte Quartal dieses Jahres ist angebrochen.

Für unser Smart Data Radar heißt das:

Was hat sich in den letzen Monaten geändert? Welche Technologien kamen neu dazu und wie ordnen wir sie ein?

Mit einer Analyse der Vergangenheit, dem Verhalten der Nutzer und ein paar KI-Zaubereien passgenaue Empfehlungen für weiteren Inhalt, Artikel oder was-auch-immer finden. So oder so ähnlich werden Recommender Systeme — auf Deutsch: Empfehlungssysteme — überspitzt definiert.
