Machine Learning with Python Cookbook Practical Solutions from Preprocessing to Deep Learning

What you’ll learn

Over the last few years machine learning has become embedded in a wide variety of day-to-day business, nonprofit, and government operations. As the popularity of machine learning increased, a cottage industry of high-quality literature that taught applied machine learning to practitioners developed. This literature has been highly successful in training an entire generation of data scientists and machine learning engineers. This literature also approached the topic of machine learning from the perspective of providing a learning resource to teach an individual what machine learning is and how it works. However, while fruitful, this approach left out a different perspective on the topic: the nuts and bolts of doing machine learning day to day. That is the motivation of this book—not as a tome of machine learning knowledge for the student but as a wrench for the professional, to sit with dog-eared pages on desks ready to solve the practical day-to-day problems of a machine learning practitioner

More specifically, the book takes a task-based approach to machine learning, with almost 200 self-contained solutions (you can copy and paste the code and it’ll run) for the most common tasks a data scientist or machine learning engineer building a model will run into.

The ultimate goal is for the book to be a reference for people building real machine learning systems. For example, imagine a reader has a JSON file containing 1,000 categorical and numerical features with missing data and categorical target vectors with imbalanced classes, and wants an interpretable model. The motivation for this book is to provide recipes to help the reader learn processes such as:

  • 2.5 Loading a JSON file
  • 4.2 Standardizing a Feature
  • 5.3 Encoding Dictionaries of Features
  • 5.4 Imputing Missing Class Values
  • 9.1 Reducing Features Using Principal Components
  • 12.2 Selecting Best Models Using Randomized Search
  • 14.4 Training a Random Forest Classifier
  • 14.7 Selecting Random Features in Random Forests

The goal is for the reader to be able to:

1. Copy/paste the code and gain confidence that it actually works with the included toy datasets.

2. Read the discussion to gain an understanding of the theory behind the technique the code is executing and learn which parameters are important to consider.

3. Insert/combine/adapt the code from the recipes to construct the actual application.

Who This Book Is For

This book is not an introduction to machine learning. If you are not comfortable with the basic concepts of machine learning or have never spent time learning machine learning, do not buy this book. Instead, this book is for the machine learning practitioner who, while comfortable with the theory and concepts of machine learning, would benefit from a quick reference containing code to solve challenges he runs into working on machine learning on an everyday basis.

This book assumes the reader is comfortable with the Python programming language and package management.

  Who This Book Is Not For

As stated previously, this book is not an introduction to machine learning. This book should not be your first. If you are unfamiliar with concepts like cross-validation, random forest, and gradient descent, you will likely not benefit from this book as much as one of the many high-quality texts specifically designed to introduce you to the topic. I recommend reading one of those books and then coming back to this book to learn working, practical solutions for machine learning.

Terminology Used in This Book

Machine learning draws upon techniques from a wide range of fields, including computer science, statistics, and mathematics. For this reason, there is significant variation in the terminology used in the discussions of machine learning:

Signal processing problems, solved in MATLAB and in Python

Applications-oriented instruction on signal processing and digital signal processing (DSP) using MATLAB and Python codes

What you’ll learn

  • Understand commonly used signal processing tools
  • Design, evaluate, and apply digital filters
  • Clean and denoise data
  • Know what to look for when something isn’t right with the data or the code
  • Improve MATLAB or Python programming skills
  • Know how to generate test signals for signal processing methods
  • *Fully manually corrected English captions!

Requirements

  • Basic programming experience in MATLAB or Python
  • High-school mathn

Description

Why you need to learn digital signal processing.

Nature is mysterious, beautiful, and complex. Trying to understand nature is deeply rewarding, but also deeply challenging. One of the big challenges in studying nature is data analysis. Nature likes to mix many sources of signals and many sources of noise into the same recordings, and this makes your job difficult.

Therefore, one of the most important goals of time series analysis and signal processing is to denoise: to separate the signals and noises that are mixed into the same data channels.

The big idea of DSP (digital signal processing) is to discover the mysteries that are hidden inside time series data, and this course will teach you the most commonly used discovery strategies.

What’s special about this course?

The main focus of this course is on implementing signal processing techniques in MATLAB and in Python. Some theory and equations are shown, but I’m guessing you are reading this because you want to implement DSP techniques on real signals, not just brush up on abstract theory.

The course comes with over 10,000 lines of MATLAB and Python code, plus sample data sets, which you can use to learn from and to adapt to your own coursework or applications.

In this course, you will also learn how to simulate signals in order to test and learn more about your signal processing and analysis methods.

Are there prerequisites?

You need some programming experience. I go through the videos in MATLAB, and you can also follow along using Octave (a free, cross-platform program that emulates MATLAB). I provide corresponding Python code if you prefer Python. You can use any other language, but you would need to do the translation yourself.

I recommend taking my Fourier Transform course before or alongside this course. However, this is not a requirement, and you can succeed in this course without taking the Fourier transform course.

What should you do now?

Watch the sample videos, and check out the reviews of my other courses — many of them are “best-seller” or “top-rated” and have lots of positive reviews. If you are unsure whether this course is right for you, then feel free to send me a message. I hope you to see you in class!

Who this course is for:

  • Students in a signal processing or digital signal processing (DSP) course
  • Scientific or industry researchers who analyze data
  • Developers who work with time series data
  • Someone who wants to refresh their knowledge about filtering
  • Engineers who learned the math of DSP and want to learn about implementations in software

PYTHON 3 FOR ABSOLUTE BEGINNERS

So, you want to learn programming. Welcome to one of the great adventures of the twenty-first century. Programming requires little in the way of specialized equipment; the software tools can all be downloaded for free off the Internet, and it can be practiced in the safety and comfort of your own home, without having to ask anyone’s permission.

This will ease you in gently by introducing you to the software you will need to create your programs: a command-line interface, which allows you to use Python in interactive mode, and a text editor for writing scripts—nothing more complicated than that.

I will also show you where to go to find help and documentation, so you can decode the sometimes-impenetrable jargon that seems to surround this, the geekiest of all technical disciplines.

To begin with, you will need to make sure that you have a decently recent version of Python installed on your machine or follow the steps later in this chapter to install it (see “Choosing the Right Python Version” for a definition of decently recent).

This chapter explains how to make sure that you have everything set up correctly and that you have suitable references at hand before you start your journey.
