Evaluate & Swap Models in Java ML

О курсе

Evaluate & Swap Models in Java ML is a practical course that teaches you how to measure, compare, and confidently replace machine learning models in Java applications. You’ll learn why high accuracy can still lead to failure in real-world systems, and how metrics like precision, recall, F1-score, and AUC-ROC reveal the real impact of model decisions, especially with imbalanced datasets. Through hands-on benchmarking in Weka or Smile, you’ll compare multiple algorithms—Logistic Regression, Decision Trees, SVMs—and analyze trade-offs based on business consequences, not just leaderboard results. You will also redesign your ML architecture for flexibility, applying interface-driven development and the Strategy Pattern to make models swappable without touching the rest of the system. Finally, you’ll implement model lifecycle safeguards including versioning, re-evaluation triggers, and safe rollback paths so deployed models remain reliable as data evolves. This course is designed for learners with basic Java skills who want to confidently evaluate, compare, and upgrade machine-learning models in real-world applications. Learners should be familiar with basic Java programming skills and a general understanding of machine learning concepts and datasets. By the end, you’ll know how to select the right model for the job today—and upgrade it rapidly when tomorrow’s needs change.
