Title
Wolfram Language erkennt Bilder
Source
Year
2015
Abstract
Wolfram Research hat seine Cloud-basierte Programmiersprache Wolfram Language um eine Funktion zur Bilderkennung erweitert. Der Hersteller des Computeralgebrasystems Mathematica und Betreiber der Wissens-Suchmaschine Wolfram Alpha hat seinem System die Erkennung von Bildern beigebracht. Mit der Funktion ImageIdentify bekommt man in Wolfram Language jetzt zu einem Bild eine symbolische Beschreibung des Inhalts, die sich in der Sprache danach sogar weiterverarbeiten lässt. Als Demo dieser Funktion dient die Website The Wolfram Language Image Identification Project: Dort kann man ein beliebiges Bild hochladen und sich das Ergebnis anschauen. Die Website speichert einen Thumbnail des hochgeladenen Bildes, sodass man einen Link zu der Ergebnisseite weitergeben kann. Wie so oft bei künstlicher Intelligenz sind die Ergebnisse manchmal lustig daneben, oft aber auch überraschend gut. Die Funktion arbeitet mit einem neuronalen Netz, das mit einigen -zig Millionen Bildern trainiert wurde und etwa 10.000 Objekte identifizieren kann.

Eine ausführlichere Erklärung der Funktionsweise und Hintergründe findet sich in Stephen Wolframs Blog-Eintrag: "Wolfram Language Artificial Intelligence: The Image Identification Project" unter: http://blog.stephenwolfram.com/2015/05/wolfram-language-artificial-intelligence-the-image-identification-project/.
