Data analysis is the process of applying logical and analytical reasoning to study each component of data present in the system. Python is a multi-domain, high-level, programming language that offers a range of tools and libraries suitable for all purposes, it has slowly evolved as one of the primary languages for data science. Have you ever imagined becoming an expert at effectively approaching data analysis problems, solving them, and extracting all of the available information from your data? If yes, look no further, this is the course you need!In this course, we will get you started with Python data analysis by introducing the basics of data analysis and supported Python libraries such as matplotlib, NumPy, and pandas. Create visualizations by choosing color maps, different shapes, sizes, and palettes then delve into statistical data analysis using distribution algorithms and correlations. You’ll then find your way around different data and numerical problems, get to grips with Spark and HDFS, and set up migration scripts for web mining. You’ll be able to quickly and accurately perform hands-on sorting, reduction, and subsequent analysis, and fully appreciate how data analysis methods can support business decision-making. Finally, you will delve into advanced techniques such as performing regression, quantifying cause and effect using Bayesian methods, and discovering how to use Python’s tools for supervised machine learning.The course provides you with highly practical content explaining data analysis with Python, from the following Packt books:1. Getting Started with Python Data Analysis.2. Python Data Analysis Cookbook.3. Mastering Python Data Analysis.By the end of this course, you will have all the knowledge you need to analyze your data with varying complexity levels, and turn it into actionable insights.
Python i praca z danymi. Przetwarzanie, analiza, modelowanie i wizualizacja. Wydanie III
Avinash Navlani, Armando Fandango, Ivan Idris
Analiza danych sprawia, że dzięki ich dużym i mniejszym kolekcjom uzyskujemy wartościową wiedzę, która pozwala na podejmowanie najlepszych decyzji. Dzieje się to poprzez odkrywanie wzorców lub trendów. Obecnie Python udostępnia przeznaczone specjalnie do tego celu narzędzia i biblioteki. Możemy więc łatwo korzystać z wyrafinowanych technik wydobywania wiedzy z danych. Aby jednak osiągnąć zamierzone efekty, trzeba dobrze poznać zarówno metodologię analizy danych, jak i zasady pracy ze służącymi do tego narzędziami. Dzięki tej książce zdobędziesz wszystkie potrzebne informacje i umiejętności, aby skutecznie używać Pythona do analizy danych. Omówiono tu niezbędne podstawy statystyki i zasady analizy danych. Wyczerpująco przedstawiono zaawansowane zagadnienia dotyczące przygotowania, przetwarzania i modelowania danych, a także ich wizualizacji. W zrozumiały sposób wyjaśniono takie procesy jak inteligentne przetwarzanie i analizowanie danych za pomocą algorytmów uczenia maszynowego: regresji, klasyfikacji, analizy głównych składowych czy analizy skupień. Nie zabrakło praktycznych przykładów przetwarzania języka naturalnego i analizy obrazów. Ciekawym zagadnieniem jest również wykonywanie obliczeń równoległych za pomocą biblioteki Dask. W książce między innymi: podstawy analizy danych i korzystanie z bibliotek NumPy i pandas praca z danymi w różnych formatach interaktywna wizualizacja z bibliotekami Matplotlib, seaborn i Bokeh inżynieria cech, analiza szeregów czasowych i przetwarzanie sygnałów zaawansowana analiza danych tekstowych i obrazów Python: wydobywaj z danych wiedzę o wielkiej wartości!
