@origin.tech.docs: Duolingo doesn’t just track what you get wrong. It predicts when you’re about to forget. Its Half-Life Regression model estimates how likely you are to remember a word over time, helping decide when that word should show up again. That’s why two people learning the same language can end up with completely different practice queues. Your lessons aren’t just following a course. They’re adapting to your memory. #Duolingo #MachineLearning #AI #TechTok #HowItWorks #EdTech #ArtificialIntelligence #TechExplained
