Скачать или смотреть Beyond 99.9% Accuracy: What AI's Numbers Really Mean (Don't Be Fooled!)

Imagine an AI that's 99.9% accurate – sounds perfect, right? Think again. That tiny 0.1% can hide catastrophic errors, putting projects, and even lives, at risk. In this eye-opening video, we pull back the curtain on AI's report card, revealing why "accuracy" alone is the most misleading number in data science.

We'll expose how a "highly accurate" AI can be utterly useless, even dangerous, by missing the very cases it's designed to find. Learn the critical questions you must ask beyond simple accuracy to truly understand an AI's performance. Discover the "Confusion Matrix" and why not all errors are created equal, breaking down the crucial difference between a "False Positive" (a false alarm) and a "False Negative" (a missed problem) – and which one could cost you everything.

Master the concepts of Sensitivity and Specificity, and understand the fundamental trade-off that defines every AI model. We'll also dive into the hidden power of "Confidence Scores" and how to tell if an AI is truly "calibrated." Finally, you'll learn to interpret the powerful "ROC Curve," allowing you to see an AI's true capabilities at a glance.

Stop being fooled by big numbers. This video equips you with the toolkit to critically evaluate any AI, ensuring you make informed decisions and build trustworthy systems.
