1 00:00:00,633 --> 00:00:01,633 Hello and welcome back. 2 00:00:01,633 --> 00:00:04,200 Today we are talking about the machine learning process. 3 00:00:04,200 --> 00:00:07,566 As you will see from the practical tutorials of this course, 4 00:00:07,766 --> 00:00:12,133 there's a specific step by step process that we typically always follow 5 00:00:12,233 --> 00:00:14,066 when building machine learning models. 6 00:00:14,066 --> 00:00:16,800 So let's have a look at what this process entails. 7 00:00:16,800 --> 00:00:18,833 This process has three main steps. 8 00:00:18,833 --> 00:00:21,500 The first one is called data preprocessing. 9 00:00:21,500 --> 00:00:23,366 And here we import the data. 10 00:00:23,366 --> 00:00:27,966 We clean the data and we split the data into training and test sets. 11 00:00:28,400 --> 00:00:32,033 A quick note is that in this course, we won't be focusing a lot 12 00:00:32,033 --> 00:00:33,133 on cleaning the data. 13 00:00:33,133 --> 00:00:37,200 That's because our data is pre cleaned so that we can really hone 14 00:00:37,200 --> 00:00:41,966 in our other skills related to machine learning, but bear in mind 15 00:00:41,966 --> 00:00:45,566 that in real world situations, clean the data is quite an important step. 16 00:00:45,800 --> 00:00:49,500 Next, we move on to modeling where we first build the model. 17 00:00:49,500 --> 00:00:52,500 Then we train the model and we make the prediction. 18 00:00:52,633 --> 00:00:54,533 So this is the fun part of machine learning. 19 00:00:54,533 --> 00:00:58,200 And in this course you'll get a great exposure to several different models. 20 00:00:58,200 --> 00:01:01,100 And you'll be able to practice your skills there. 21 00:01:01,100 --> 00:01:03,966 And finally we move on to evaluations. 22 00:01:03,966 --> 00:01:08,666 We will calculate some performance metrics and make a verdict about our model, 23 00:01:08,666 --> 00:01:13,033 whether it's a good fitting model and if it works for our data or not. 24 00:01:13,033 --> 00:01:16,366 And this is a very important step to make sure that the models 25 00:01:16,366 --> 00:01:19,366 we built really serve the purpose that they're designed for. 26 00:01:19,666 --> 00:01:20,333 So there we go. 27 00:01:20,333 --> 00:01:21,633 That's the machine learning process. 28 00:01:21,633 --> 00:01:24,866 And in this course, you'll definitely have lots of opportunities to get 29 00:01:24,866 --> 00:01:27,866 some great hands on experience with it. 30 00:01:27,966 --> 00:01:29,200 And I look forward to seeing you next time. 31 00:01:29,200 --> 00:01:30,900 Until then, enjoy machine learning.
