Practical Graph Analytics with Apache Giraph helps you build data mining and machine learning applications using the Apache Foundation’s Giraph framework for graph processing. This is the same framework as used by Facebook, Google, and other social media analytics operations to derive business value from vast amounts of interconnected data points. Graphs arise in a wealth of data scenarios and describe the connections that are naturally formed in both digital and real worlds. Examples of such connections abound in online social networks such as Facebook and Twitter, among users who rate movies from services like Netflix and Amazon Prime, and are useful even in the context of biological networks for scientific research. Whether in the context of business or science, viewing data as connected adds value by increasing the amount of information available to be drawn from that data and put to use in generating new revenue or scientific opportunities. Apache Giraph offers a simple yet flexible programming model targeted to graph algorithms and designed to scale easily to accommodate massive amounts of data. Originally developed at Yahoo!, Giraph is now a top top-level project at the Apache Foundation, and it enlists contributors from companies such as Facebook, LinkedIn, and Twitter. Practical Graph Analytics with Apache Giraph brings the power of Apache Giraph to you, showing how to harness the power of graph processing for your own data by building sophisticated graph analytics applications using the very same framework that is relied upon by some of the largest players in the industry today.

Was wäre, wenn deine große Liebe nach langen Jahren wieder auftaucht? Darfst du alles riskieren für einen Traum? Für das ganz große Glück? Keiner schreibt so unnachahmlich über Männer und Gefühle wie ›Das Rosie-Projekt‹-Autor Simsion. Adam Sharp gefällt sein Leben: er lebt mit Claire zusammen, arbeitet als IT-Berater in London und gewinnt beim Pub-Quiz alle Musikfragen. Aber ab und zu überkommt ihn die Erinnerung an Angelina Brown. Vor über 20 Jahren, im sonnigen Melbourne, erlebte er mit ihr, was es bedeutet, wenn man die Liebe findet – und sie verliert. Wie wäre sein Leben verlaufen, wenn er sie damals nicht hätte gehen lassen? Völlig überraschend meldet sich Angelina bei ihm. Was will sie? Haben die Songs doch recht, die von der ewigen Liebe erzählen? Sie lädt ihn in ihr Landhaus nach Frankreich ein. Adam muss sich fragen: wieviel Risiko darf man eingehen, wenn Träume auf einmal wahr werden könnten? Der große Roman über die Mitte des Lebens und das Gefühl, noch jung zu sein, übers Begegnen und Auseinanderleben, und eigentlich darüber, ob in der Liebe gestern und heute zusammenpassen. Der neue Roman vom Autor des Weltbestsellers ›Das Rosie-Projekt‹, Graeme Simsion.

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.
