1 00:00:00,000 --> 00:00:04,491 [MUSIC] 2 00:00:04,491 --> 00:00:07,590 Classifiers have really changed the world. 3 00:00:07,590 --> 00:00:09,080 Today we take classifiers for 4 00:00:09,080 --> 00:00:13,330 granted but they're at the core of every piece of technology that we enjoy. 5 00:00:13,330 --> 00:00:17,960 Be it the spam filters we talked about, dealing with our email, what happens 6 00:00:17,960 --> 00:00:22,240 when you type on the web search and get a particular set of answers back, 7 00:00:22,240 --> 00:00:27,250 what odds get shown to you, what products get recommended and 8 00:00:28,630 --> 00:00:32,150 how we classify somebody's medical conditions and more. 9 00:00:32,150 --> 00:00:36,190 And we see that all over the world, happening everyday. 10 00:00:36,190 --> 00:00:39,160 And interesting thing about classifiers, is that the fundamental techniques that 11 00:00:39,160 --> 00:00:42,990 you need to build a classifier, are very similar to those that you need to build 12 00:00:42,990 --> 00:00:46,100 all other sorts of machine leaning that models. 13 00:00:46,100 --> 00:00:51,090 And so, if you really understand classifiers in depth, you'll be able to do 14 00:00:51,090 --> 00:00:55,600 basically all kinds of machine learning, what's called supervised learning. 15 00:00:55,600 --> 00:01:00,117 And that's in the core of most real world applications of machine learning today. 16 00:01:00,117 --> 00:01:04,809 [MUSIC]
