Big data
Korporacyjne jezioro danych. Wykorzystaj potencjał big data w swojej organizacji
Alex Gorelik
Koncepcja big data, nauka o danych i analityka danych wspomagają dziś procesy decyzyjne w przedsiębiorstwach w niespotykanym wcześniej zakresie. Zwiększają poziom efektywności pracy w wielu różnych branżach. Korporacje zaczęły więc eksperymenty z wykorzystaniem big data i technologii chmury, aby budować jeziora danych oraz tworzyć oparte na nich systemy podejmowania decyzji. Niejeden z tych projektów się nie powiódł, gdyż nie został dostosowany do kultury i potrzeb przedsiębiorstwa. Najwyraźniej zabrakło wiedzy, w jaki sposób skutecznie przeprowadzać tak radykalną transformację. Ta książka jest praktycznym przewodnikiem, który ułatwia wdrażanie architektury jeziora danych (ang. data lake) w przedsiębiorstwie. Omówiono tu różne podejścia do jej uruchamiania i rozwijania, w tym kałuże danych (analityczne piaskownice) i stawy danych (hurtownie danych), a także budowanie jezior danych od podstaw. Opisano konfigurowanie różnych stref, co pozwala na odpowiednie rozmieszczenie zarówno surowych, jak i starannie zarządzanych i przetworzonych danych. Wyjaśniono znaczenie zarządzania dostępem do stref. Zawarto tu również wskazówki umożliwiające zachowanie zgodności z regułami zarządzania danymi przedsiębiorstwa. W tej książce: wprowadzenie do hurtowni danych, big data i nauki o danych praktyczne techniki budowania jezior danych najlepsze praktyki dostarczania analitykom dostępu do danych projektowanie architektury jeziora danych oraz różne techniki implementacji zalety i wady różnych podejść do budowania magazynów danych i zarządzania nimi Jeziora danych i big data - ocean możliwości!

Large Python machine learning projects involve new problems associated with specialized machine learning architectures and designs that many data scientists have yet to tackle. But finding algorithms and designing and building platforms that deal with large sets of data is a growing need. Data scientists have to manage and maintain increasingly complex data projects, and with the rise of big data comes an increasing demand for computational and algorithmic efficiency. Large Scale Machine Learning with Python uncovers a new wave of machine learning algorithms that meet scalability demands together with a high predictive accuracy. Dive into scalable machine learning and the three forms of scalability. Speed up algorithms that can be used on a desktop computer with tips on parallelization and memory allocation. Get to grips with new algorithms that are specifically designed for large projects and can handle bigger files, and learn about machine learning in big data environments. We will also cover the most effective machine learning techniques on a map reduce framework in Hadoop and Spark in Python.
