Classification Models and Decision Criteria in Machine Learning

Understanding how predictive models categorize information is a cornerstone of modern machine learning. This comprehensive text-based course breaks down the core concepts behind classification algorithms and teaches you how to establish optimal decision boundaries for reliable predictions. You will develop a firm foundation in supervised classification, learning how models estimate probabilities, balance trade-offs, and turn data into categorical outcomes. What you'll learn: - Understand essential terminology, classification concepts, and probability estimation basics - Build fundamental classification models including logistic regression and decision trees - Evaluate performance using confusion matrices, precision, recall, F1-scores, and ROC-AUC metrics - Apply decision threshold tuning to align model behavior with practical requirements - Address real-world challenges such as class imbalance and feature scaling - Practice structured evaluation workflows to compare and select the most effective model for your data. The course begins with core terminology and foundational mathematical concepts before guiding you through model training, metric analysis, and threshold calibration using clear written explanations and code examples. Designed for beginners in data science, aspiring developers, and analytical thinkers, no prior machine learning experience is required.
