Machine Learning Evaluation Metrics: Assess AI Model Performance

Building a machine learning model is only half the battle; knowing how to accurately measure its success is what separates great models from failed deployments. This text-based course demystifies the mathematical and practical concepts behind AI performance evaluation. You will transition from guessing how well your models perform to confidently choosing and calculating the exact metrics needed for regression, classification, and modern generative AI tasks. What you'll learn: - Understand the foundational concepts of model evaluation, including overfitting, underfitting, and the bias-variance tradeoff. - Calculate and interpret key classification metrics such as precision, recall, F1-score, and the confusion matrix. - Apply regression metrics like MAE, RMSE, and R-squared to continuous data predictions. - Analyze ROC curves and AUC to optimize classification thresholds for imbalanced datasets. - Explore modern evaluation paradigms, including basic metrics for assessing large language models and generative outputs. Starting with essential terminology, you will progress through structured text lessons and written exercises designed to solidify your understanding of statistical evaluation. You will learn to match the right metric to the right business problem without relying on automated black-box tools. This course is designed for beginner data scientists, analysts, and software engineers looking to build a strong theoretical and practical foundation in AI model assessment, with no advanced mathematical background required.
