Practical Data Science Cookbook - Second Edition oleh Abhijit Dasgupta

Key FeaturesTackle every step in the data science pipeline and use it to acquire, clean, analyze, and visualize your dataGet beyond the theory and implement real-world projects in data science using R and PythonEasy-to-follow recipes will help you understand and implement the numerical computing conceptsBook DescriptionAs increasing amounts of data are generated each year, the need to analyze and create value out of it is more important than ever. Companies that know what to do with their data and how to do it well will have a competitive advantage over companies that dont. Because of this, there will be an increasing demand for people that possess both the analytical and technical abilities to extract valuable insights from data and create valuable solutions that put those insights to use.Starting with the basics, this book covers how to set up your numerical programming environment, introduces you to the data science pipeline, and guides you through several data projects in a step-by-step format. By sequentially working through the steps in each chapter, you will quickly familiarize yourself with the process and learn how to apply it to a variety of situations with examples using the two most popular programming languages for data analysis—R and Python.What you will learnLearn and understand the installation procedure and environment required for R and Python on various platformsPrepare data for analysis by implement various data science concepts such as acquisition, cleaning and munging through R and PythonBuild a predictive model and an exploratory modelAnalyze the results of your model and create reports on the acquired dataBuild various tree-based methods and Build random forestAbout the AuthorPrabhanjan Tattar has 9 years of experience as a statistical analyst. His main thurst has been to explain statistical and machine learning techniques through elegant programming which will clear the nuances of the underlying mathematics. Survival analysis and statistical inference are his main areas of research/interest, and he has published several research papers in peer-reviewed journals and also has authored two books on R: R Statistical Application Development by Example, Packt Publishing, and A Course in Statistics with R, Wiley. He also maintains the R packages gpk, RSADBE, and ACSWR.Tony Ojeda is an accomplished data scientist and entrepreneur, with expertise in business process optimization and over a decade of experience creating and implementing innovative data products and solutions.
