@dgm.america: Nobody taught your spam filter what spam is. It learned. That's machine learning: a computer learns the rules from examples, instead of a person writing them. How it learns: guess → check the real answer → nudge its settings → repeat, millions of times. That's training. The result is a model. 3 ways to train: 1. With answers (photos labelled cat / dog) 2. Without answers (it finds groups on its own) 3. Trial and error (points for every win) The one thing that decides how good it gets: the examples. In one famous test, every wolf photo had snow in it. So the model learned "snow = wolf" and called a husky in snow a wolf. Save this for the next time someone says machine learning. 🔖 #machinelearning #AI #learnAI #AIexplained #techexplained
