Читать книгу Becoming a Data Head - Alex J. Gutman - Страница 28

This book will help you construct a mental model of data science, statistics, and machine learning. What is a mental model? It's “a simplified representation of the most important parts of some problem domain that is good enough to enable problem solving.”⁶ Think of it as a new storage room in your brain where you can put information.

Some books and articles start with a list of definitions: “Machine Learning is …”, “Deep Learning is …”, etc. Seeing a list of technical definitions without a mental model to fit the information into would be like someone dropping off boxes of clothes when you don't have a place to store them. Sooner or later, it's all going to end up in the garbage.

But with a newly constructed mental model, you will learn how to think, speak, and understand data. You'll become a Data Head.

Specifically, by reading this book, you will be able to:

 Think statistically and understand the role variation plays in your life and decision making.

 Become data literate—speak intelligently and ask the right questions about the statistics and results you encounter in the workplace.

 Understand what's really going on with machine learning, text analytics, deep learning, and artificial intelligence.

 Avoid common pitfalls when working with and interpreting data.
