## Review of Data Science from Scratch

The following is a review of the book Data Science from Scratch: First Principles with Python by Joel Grus.

**Data Science from scratch** is one of the top books out there for getting started with Data Science. It’s second edition has recently been published, upgrading and improving the content of the first one. Lets see what this awesome book offers.

We will begin by clarifying who this book is for: it is for people with at least some sort of programming knowledge in Python, and some basic algebra and statistics knowledge. If you are not there yet, take a look at our awesome recommended Python Programming books, and our Statistics and probability courses. If you meet the above pre-requisites, and want to learn Data Science from a basic level then you will love this book.

The author does a great job explaining the topics and introducing little pinches of humor every now and then to keep the reading entertaining, even in the most complex topics. If you are considering going into Machine Learning and Data Science, this book is a great first step.

It will teach you the most fundamental data science concepts, encouraging you to write simple functions of code so that you really learn what is happening under the hood of the most popular Python Data Science libraries like Numpy, Pandas and Scikit Learn.

In our opinion this a great way of learning, as it gives you a through practical understanding of how these libraries work instead of just teaching you to use the most common functions. You will have a very strong foundation, that will allow you to learn easier and progress with more confidence than what you can adquiere from other resources.

It is a really pedagogical book, and a great read to develop an strong understanding of the fundamental concepts necessary to understand data science and machine learning.

## Book Description and Contents

To really learn data science, you should not only master the tools—data science libraries, frameworks, modules, and toolkits—but also understand the ideas and principles underlying them. Updated for Python 3.6, this second edition of Data Science from Scratch shows you how these tools and algorithms work by implementing them from scratch.

If you have an aptitude for mathematics and some programming skills, author Joel Grus will help you get comfortable with the math and statistics at the core of data science, and with the hacking skills you need to get started as a data scientist. Packed with New material on deep learning, statistics, and natural language processing, this updated book shows you how to find the gems in today’s messy glut of data.

- Get a crash course in Python
- Learn the basics of linear algebra, statistics, and probability—and how and when they’re used in data science
- Collect, explore, clean, munge, and manipulate data
- Dive into the fundamentals of machine learning
- Implement models such as k-nearest neighbors, Naïve Bayes, linear and logistic regression, decision trees, neural networks, and clustering
- Explore recommender systems, natural language processing, network analysis, MapReduce, and databases.
