Episode 10 — ML 101: Supervised Learning in Plain Language
This episode explains supervised learning, one of the most fundamental approaches in machine learning and a cornerstone for certification exams. Supervised learning relies on labeled datasets where each input is paired with a correct output. The model learns to map inputs to outputs through examples, producing predictions for new, unseen cases. Key concepts include training, testing, generalization, and error measurement. Supervised learning underpins many widely used applications such as spam detection, fraud monitoring, and medical diagnosis, making it essential knowledge for both exams and real-world use.
To deepen understanding, we review common supervised learning tasks: classification, where categories are predicted, and regression, where continuous values are estimated. Examples include classifying emails as spam or not, and predicting housing prices based on features like location and size. Troubleshooting issues include overfitting, underfitting, and imbalanced classes, all of which may appear in test scenarios. Best practices include using diverse datasets, cross-validation, and monitoring metrics beyond accuracy, such as precision and recall. By the end of this episode, learners will have a clear, practical grasp of supervised learning fundamentals that will support future topics in the series.
