Now imagine teaching your little sibling to recognize a dog. You just don't hand them a biology textbook that has all the details about the features of a dog. Instead, you show them pictures, right? That's exactly what machine learning does too. It uses a whole lot of data, runs it through various algorithms, trains a model, and then starts making predictions. So, the more data you feed it, the better it gets.
So, "Where's the cool part?" you may ask. ML fills a major part of artificial intelligence, but don't get caught up in all the complex lingos and terms. Just know that when your phone recognizes your face and voice and filters your spam by itself, it is ML doing the job in the background.
Why Machine Learning Matters Today
Do you still think machine learning is only something used by coders and people involved in tech? That's where things get a little different. It's already something you're using every day. From what you listen to on your 'specially curated playlists,' your 'For You' social media sections, and even your grocery reminders. Everything runs on machine learning models.
