Machine Learning with Python

By: Oliver Theobald

Overview of this book

The course starts by setting the foundation with an introduction to machine learning, Python, and essential libraries, ensuring you grasp the basics before diving deeper. It then progresses through exploratory data analysis, data scrubbing, and pre-model algorithms, equipping you with the skills to understand and prepare your data for modeling. The journey continues with detailed walkthroughs on creating, evaluating, and optimizing machine learning models, covering key algorithms such as linear and logistic regression, support vector machines, k-nearest neighbors, and tree-based methods. Each section is designed to build upon the previous, reinforcing learning and application of concepts. Wrapping up, the course introduces the next steps, including an introduction to Python for newcomers, ensuring a comprehensive understanding of machine learning applications.

MODEL DESIGN

 

Before we explore specific supervised learning algorithms, it’s useful to pause and take a high-level look at the full procedure of building a machine learning model. This involves reviewing a number of steps examined in the preceding chapters as well as new methods including evaluate and predict. These 10 steps take place inside your development environment and follow a relatively fixed sequence. Once you are familiar with this framework, you will find it easy to design your own machine learning models from start to finish.

1) Import libraries

Given the Python interpreter works from top to bottom through your code, it’s vital to import libraries before calling any of their specific functions. If you attempt to create a heatmap or pairplot without first importing Seaborn and Matplolib, the Python interpreter won’t be able to process your request.

The libraries...
