Course OVERVIEW

Description

CPE Credits: 2 Field of Study: Information Technology
Delivery Method: QAS Self Study

Knowledge on various machine learning algorithms is essential for machine learning enthusiasts and specialists. This course focuses on a specific type of classifier – the Naïve Bayes one. It is famous for being a quick learner and a real-time problem solver. Not only will you learn the theoretical foundations behind the Bayesian approach, but you will also get the chance to solve a real-life problem using scikit-learn’s Naïve Bayes algorithms.

Prerequisites

Python (version 3.8 or later), Streamlit library, OpenAI API key, and a code editor or IDE (e.g., VS Code or Jupyter Notebook)
Intermediate Python skills are required.
Familiarity with basic statistics and linear algebra is helpful but not mandatory.

1. Bayes' Theorem

27 Min

This section serves as a theoretical introduction to the Bayesian approach which will later help us understand the Naïve Bayes machine learning classification algorithm. We start with an intuitive example which Thomas Bayes himself introduced. Then, we dive into the mathematics behind his approach and derive Bayes’ theorem. Finally, we apply this theorem to classify an e-mail message as a spam or not-spam (also known as a ham).

3. Naïve Bayes Algorithm - Practical Example

40 Min

This is the practical section of the course where we roll our sleeves up and build our very own classification model. We use a dataset containing YouTube comments – some well-intended and others harmful. Our task is to train a model that could later serve as a spam comment detector. To do this, we make use of Python’s scikit-learn library, where a Naïve Bayes algorithm is implemented. Throughout this section, we will study the inner workings of the algorithm and learn how to interpret performance metrics such as accuracy, precision, recall, and F1 score.

When I first discovered data science, I had no background in math or analytics and felt it was out of reach. I spent nearly a year learning from free resources but struggled to make progress. 365 Data Science changed everything. The structured courses and supportive instructors helped me grasp complex topics like statistics with ease. Today, I proudly call myself a data scientist, contribute to data communities, and volunteer with Data for Good—thanks to the solid foundation 365 gave me.

As a Data Science student, I feared graduating without the practical skills to succeed. 365 Data Science gave me exactly what I needed—projects, career tracks, and in-depth courses in Python, R, SQL, Excel, Power BI, Tableau, and more. I applied these skills to university projects, built advanced solutions like chatbots, and understood the big picture. The structured learning, real-world applications, and interview preparation boosted my confidence, helping me become the top student in my class and ready for the industry.

My journey in data started during the pandemic, when I joined 365 Data Science. The well-organized roadmap took me from basic topics like SQL to advanced concepts, helping me transition from a beginner to a professional data engineer. I built strong foundations in Python and SQL, which launched my career in data analysis and engineering. Even now, 365 continues to boost my skills and career growth, thanks to its engaging and well-structured courses.
