Neuronale Netze sind Schlüsselelemente des Deep Learning und der Künstlichen Intelligenz, die heute zu Erstaunlichem in der Lage sind. Sie sind Grundlage vieler Anwendungen im Alltag wie beispielsweise Spracherkennung, Gesichtserkennung auf Fotos oder die Umwandlung von Sprache in Text. Dennoch verstehen nur wenige, wie neuronale Netze tatsächlich funktionieren. Dieses Buch nimmt Sie mit auf eine unterhaltsame Reise, die mit ganz einfachen Ideen beginnt und Ihnen Schritt für Schritt zeigt, wie neuronale Netze arbeiten: - Zunächst lernen Sie die mathematischen Konzepte kennen, die den neuronalen Netzen zugrunde liegen. Dafür brauchen Sie keine tieferen Mathematikkenntnisse, denn alle mathematischen Ideen werden behutsam und mit vielen Illustrationen und Beispielen erläutert. Eine Kurzeinführung in die Analysis unterstützt Sie dabei. - Dann geht es in die Praxis: Nach einer Einführung in die populäre und leicht zu lernende Programmiersprache Python bauen Sie allmählich Ihr eigenes neuronales Netz mit Python auf. Sie bringen ihm bei, handgeschriebene Zahlen zu erkennen, bis es eine Performance wie ein professionell entwickeltes Netz erreicht. - Im nächsten Schritt tunen Sie die Leistung Ihres neuronalen Netzes so weit, dass es eine Zahlenerkennung von 98 % erreicht – nur mit einfachen Ideen und simplem Code. Sie testen das Netz mit Ihrer eigenen Handschrift und werfen noch einen Blick in das mysteriöse Innere eines neuronalen Netzes. - Zum Schluss lassen Sie das neuronale Netz auf einem Raspberry Pi Zero laufen. Tariq Rashid erklärt diese schwierige Materie außergewöhnlich klar und verständlich, dadurch werden neuronale Netze für jeden Interessierten zugänglich und praktisch nachvollziehbar.

Was lernen Sie in diesem Buch? Haben Sie sich schon einmal gewünscht, Sie könnten mit nur einem Buch Python richtig lernen? Mit Python von Kopf bis Fuß schaffen Sie es! Durch die ausgefeilte Von-Kopf-bis-Fuß-Didaktik, die viel mehr als die bloße Syntax und typische How-to-Erklärungen bietet, wird es sogar zum Vergnügen. Python-Grundlagen wie Datenstrukturen und Funktionen verstehen Sie hier schnell, und dann geht es auch schon weiter: Sie programmieren Ihre eigene Web-App, erkunden Datenbank-Management, Ausnahmebehandlung und die Verarbeitung von Daten. Da Python häufig im Data-Science-Umfeld eingesetzt wird, haben in der 2. Auflage diejenigen Techniken ein stärkeres Gewicht bekommen, die in der Welt der Big Data genutzt werden. Wieso sieht dieses Buch so anders aus? In diesem Buch sind die neuesten Erkenntnisse der Kognitionswissenschaft und der Lerntheorie eingeflossen, um Ihnen das Lernen so einfach wie möglich zu machen. Statt einschläfernder Bleiwüsten verwendet dieses Buch eine Vielzahl von Abbildungen und Textstilen, die Ihnen das Wissen direkt ins Hirn spielen – und zwar so, dass es sitzt.
