After this, you will move on to a data analytics specialization-predictive analytics. Social media and IOT have resulted in an avalanche of data. You will get started with predictive analytics using Python. You will see how to create predictive models from data. You will get balanced information on statistical and mathematical concepts, and implement them in Python using libraries such as Pandas, scikit-learn, and NumPy. You'll learn more about the best predictive modeling algorithms such as Linear Regression, Decision Tree, and Logistic Regression. Finally, you will master best practices in predictive modeling. After this, you will get all the practical guidance you need to help you on the journey to effective data visualization. Starting with a chapter on data frameworks, which explains the transformation of data into information and eventually knowledge, this path subsequently cover the complete visualization process using the most popular Python libraries with working examples This Learning Path combines some of the best that Packt has to offer in one complete, curated package. It includes content from the following Packt products: ? Getting Started with Python Data Analysis, Phuong Vo.T.H &Martin Czygan ? Learning Predictive Analytics with Python, Ashish Kumar ? Mastering Python Data Visualization, Kirthi Raman Style and approach The course acts as a step-by-step guide to get you familiar with data analysis and the libraries supported by Python with the help of real-world examples and datasets. It also helps you gain practical insights into predictive modeling by implementing predictive-analytics algorithms on public datasets with Python. The course offers a wealth of practical guidance to help you on this journey to data visualization

Learn to use powerful Python libraries for effective data processing and analysis About This Book * Learn the basic processing steps in data analysis and how to use Python in this area through supported packages, especially Numpy, Pandas, and Matplotlib * Create, manipulate, and analyze your data to extract useful information to optimize your system * A hands-on guide to help you learn data analysis using Python Who This Book Is For If you are a Python developer who wants to get started with data analysis and you need a quick introductory guide to the python data analysis libraries, then this book is for you. What You Will Learn * Understand the importance of data analysis and get familiar with its processing steps * Get acquainted with Numpy to use with arrays and array-oriented computing in data analysis * Create effective visualizations to present your data using Matplotlib * Process and analyze data using the time series capabilities of Pandas * Interact with different kind of database systems, such as file, disk format, Mongo, and Redis * Apply the supported Python package to data analysis applications through examples * Explore predictive analytics and machine learning algorithms using Scikit-learn, a Python library In Detail Data analysis is the process of applying logical and analytical reasoning to study each component of data. Python is a multi-domain, high-level, programming language. It's often used as a scripting language because of its forgiving syntax and operability with a wide variety of different eco-systems. Python has powerful standard libraries or toolkits such as Pylearn2 and Hebel, which offers a fast, reliable, cross-platform environment for data analysis. With this book, we will get you started with Python data analysis and show you what its advantages are. The book starts by introducing the principles of data analysis and supported libraries, along with NumPy basics for statistic and data processing. Next it provides an overview of the Pandas package and uses its powerful features to solve data processing problems. Moving on, the book takes you through a brief overview of the Matplotlib API and some common plotting functions for DataFrame such as plot. Next, it will teach you to manipulate the time and data structure, and load and store data in a file or database using Python packages. The book will also teach you how to apply powerful packages in Python to process raw data into pure and helpful data using examples. Finally, the book gives you a brief overview of machine learning algorithms, that is, applying data analysis results to make decisions or build helpful products, such as recommendations and predictions using scikit-learn. Style and approach This is an easy-to-follow, step-by-step guide to get you familiar with data analysis and the libraries supported by Python. Topics are explained with real-world examples wherever required.

Studienarbeit aus dem Jahr 2005 im Fachbereich Informatik - Software, einseitig bedruckt, Note: 1, Universit t Leipzig (Institut f r angewandte Telematik), Veranstaltung: Wegweisende Arbeiten in der Softwaretechnik II. WS 2004/2005., Sprache: Deutsch, Abstract: Die vorliegende Ausarbeitung stellt das Konzept der Assertions vor. Assertions stellen eine Umsetzung des Design-by-Contract-Prinzips dar und erm glichen eine berwachung von Code zur Laufzeit. Im folgenden sollen, ausgehend von David S. Rosenblums Paper "Toward a Method of Programming with Assertions" sowohl das Konzept der Assertions, als auch das Prinzip von Design-By-Contract vorgestellt werden. (Erg nzt wird dieser Text durch eine weitere Ausarbeitung im Rahmen des o.g. Seminars. Titel: Assertions in Java )
