1 00:00:01,070 --> 00:00:07,930 They see injuries for regression and classification have a number of advantages over the classical approaches, 2 00:00:08,000 --> 00:00:12,700 such as linear regression, logistic regression or linear discriminant analysis. 3 00:00:14,870 --> 00:00:17,750 Here are some of the advantages of the Henries. 4 00:00:20,160 --> 00:00:22,920 Foster's trees are very easy to explain to people. 5 00:00:23,310 --> 00:00:27,540 In fact, they are even easier to explain than linear regression. 6 00:00:29,140 --> 00:00:35,890 Secondly, some people believe that this country's more closely mirror human decision making, then 7 00:00:36,010 --> 00:00:40,900 regression or classification approaches based on linear regression or logistic regression. 8 00:00:42,910 --> 00:00:49,840 Thirdly, trees can be displayed graphically and are very easily interpreted even by a non expert. 9 00:00:51,340 --> 00:00:58,210 And lastly, trees can easily handle qualitative predictors without the need to create dummy variables. 10 00:00:59,410 --> 00:01:05,350 As for the disadvantages, that is one major disadvantage of a simple importunity entry. 11 00:01:07,150 --> 00:01:14,400 A simple entry generally does not have the same level of predictive accuracy as some of the other regulation 12 00:01:14,400 --> 00:01:15,810 or classification approaches. 13 00:01:17,020 --> 00:01:20,470 But by aggregating many decision trees. 14 00:01:21,440 --> 00:01:27,980 Or what we call as creating ensembles, we can significantly improve the performance of visionary's. 15 00:01:29,360 --> 00:01:32,840 We'll be looking at on sampling techniques in the coming videos.
