Employee attrition is one of the biggest challenges organizations face today. Companies invest heavily in hiring and training employees, but when employees leave unexpectedly, it creates financial loss and operational challenges. Predicting employee attrition using data-driven approaches helps organizations take proactive measures to retain talent.

In this hands-on project-based course, you will learn how to build a complete Employee Attrition Prediction system using Apache Spark and Spark MLlib. This course is designed for data engineers, data scientists, and ML enthusiasts who want to gain real-world experience with Spark Machine Learning by solving a business-critical HR analytics problem.

We will begin with Apache Spark basics — setting up the environment, provisioning a cluster, and working with notebooks in both Zeppelin and Databricks. You will learn how to explore, clean, and transform HR datasets with Spark DataFrames. Then, we’ll dive deep into feature engineering, model training, and evaluation using Spark MLlib.

By the end of this course, you will not only have built a fully working attrition prediction model but also understand how to apply Spark ML workflows to other real-world business scenarios.

This is a practical, project-driven course — no boring theory, just step-by-step implementation with real datasets, clear explanations, and guidance to help you become confident in applying Spark MLlib for predictive analytics.

Key highlights of the course:

• Understand the business problem of employee attrition and why it matters.

• Learn to set up Apache Spark locally and on Databricks (free account).

• Work with Spark DataFrames for data manipulation.

• Explore and understand the HR dataset used for attrition analysis.

• Perform data preprocessing and handle categorical variables.

• Build feature vectors using StringIndexer and VectorAssembler.

• Train a classification model in Spark MLlib to predict employee attrition.

• Evaluate the model with classification metrics like Accuracy, Precision, Recall, and F1-score.

• Optimize your ML pipeline and improve prediction performance.

• Deploy and interpret results for business decision-making.

• Gain experience with both on-premise Zeppelin and cloud-based Databricks workflows.

Whether you are a student, professional, or aspiring data engineer/scientist, this course will equip you with the skills and hands-on practice you need to work on real Spark ML projects.
