Overview of this book

Python, a multi-paradigm programming language, has become the language of choice for data scientists for data analysis, visualization, and machine learning. Ever imagined how to become an expert at effectively approaching data analysis problems, solving them, and extracting all of the available information from your data? Well, look no further, this is the book you want! Through this comprehensive guide, you will explore data and present results and conclusions from statistical analysis in a meaningful way. You’ll be able to quickly and accurately perform the hands-on sorting, reduction, and subsequent analysis, and fully appreciate how data analysis methods can support business decision-making. You’ll start off by learning about the tools available for data analysis in Python and will then explore the statistical models that are used to identify patterns in data. Gradually, you’ll move on to review statistical inference using Python, Pandas, and SciPy. After that, we’ll focus on performing regression using computational tools and you’ll get to understand the problem of identifying clusters in data in an algorithmic way. Finally, we delve into advanced techniques to quantify cause and effect using Bayesian methods and you’ll discover how to use Python’s tools for supervised machine learning.

Introduction to machine learning


There are three main categories of machine learning: supervised, unsupervised, and reinforced. Given a simple dataset with input x and output y, supervised learning is when both x and y have known labels. The algorithm maps x to y and after training, it can predict y values with x as input. Contrary to this, unsupervised learning is when only x is labeled and the algorithm finds a label for y itself. Reinforced learning is when the computer learns without the need to map the input to an outcome and instead responds to the input. This is how algorithms that play chess or other games work.

They try to predict how to react to input without a clearly quantifiable outcome, instead seeking reinforcement; one example being to play the game continuously until it ends without making a mistake (that is, win). One feature-rich and popular package for machine learning in Python is Scikit-learn.
