Machine Learning with Python

This course explores a range of techniques for building machine learning pipelines with Python. You'll learn how to carry out preprocessing techniques with the Python library scikit-learn and then build a machine learning model from it. We'll also cover PyTorch, another machine learning library in Python, and you'll understand how to create tensors and datasets, as well as how to use the autograd module and backpropagation.

You'll then put your newly acquired skills to the test with two lab challenges that focus on the data preprocessing, fitting, and evaluation of both a classification model and a regression model.

Learning Objectives

• Learn how to carry out the different preprocessing methods in scikit-learn
• Understand the pros and cons of transforming original data into a machine learning pipeline
• Deal with categorical variables inside a pipeline
• Manage the imputation of missing values
• Explore supervised-learning techniques used to train a model in scikit-learn by using a simple regression model
• Understand the concept of the bias-variance trade-off and regularized ML models
• Explore linear models for classification and how to evaluate them 
• Create a tensor in PyTorch
• Understand when to use the autograd attribute
• Create a dataset in PyTorch
• Understand what backpropagation is and why it is important

Intended Audience

This course is intended for anyone interested in machine learning, and especially for data scientists and data engineers.

Prerequisites

To get the most out of this course, you should be familiar with Python, as well as with the basics of machine learning. It's recommended that you take our Introduction to Machine Learning Concepts course before taking this one. To follow along with the PyTorch 101 course, you should have PyTorch version 1.5 or later.
