Скачать или смотреть Evaluating Models Class 10 AI (Code 417) | Accuracy, Precision, Recall & F1 Score Explained

Evaluating Models Class 10 AI Code 417 made crystal clear—learn how AI models are tested, trusted, and improved using accuracy, precision, recall & F1 score in one powerful session.

This lecture takes you inside Evaluating Models – Unit 3 (Part B, 10 Marks) of CBSE Class 10 Artificial Intelligence (AI 417), where models stop guessing and start proving themselves. If you’ve ever wondered how we decide whether an AI model is good or dangerous, this is where the truth lives.

Using board-aligned language, real-life analogies, and step-by-step activities, you’ll learn why accuracy alone can mislead, how confusion matrices expose model behaviour, and when precision, recall, or F1 score becomes the right choice—especially for unbalanced datasets like medical diagnosis or fraud detection.

This is not decorative theory. This is exam-ready clarity, grounded in CBSE expectations and extended toward real-world AI thinking—perfect for Class 9–12 students, competitive learners, and anyone stepping into BCA, MCA, BTech, or MTech foundations.
