Course Description

Bayesian Thinking Course Overview

Bayesian methods give us an alternative way to think about probability, with applications in business decision-making.

While traditional statistics requires us to observe a meaningful sample to inform decisions, Bayesian methods allow a "best guess" approach based on the information available. These approaches also allow us to include other information such as beliefs and outside knowledge.

This course will take you on a step-by-step journey, from traditional statistical approaches, through conditional probability and Bayes Theorem. These concepts will form a foundation to help you understand two basic Machine-Learning examples introduced in the course. In the end, you'll produce a real-world classification model using Python.

Bayesian Thinking Objectives

Upon completing this course, you will be able to:

  • Describe, compare, and contrast the three main approaches to probability

  • Understand the fundamentals of the Bayesian approach—such as conditional probability, priors, and updating beliefs

  • Apply Bayesian methods such as Bayes theorem and contingency tables to simple problems

  • Describe two Bayesian machine learning methods—multinomial and gaussian Bayes classifiers

  • Recognize the benefits of using these machine learning methods for modeling complex scenarios

  • Evaluate the results of the machine learning tests against business goals in Python
