About this video:
A Decision Tree recursively splits training data into subsets based on the value of a single attribute. Each split corresponds to a node in the. Splitting stops when every subset is pure (all elements belong to a single class) -- this can always be achieved, unless there are duplicate training examples with different classes.
About Unfold Data science: This channel is to help people understand basics of data science through simple examples in easy way. Anybody without having prior knowledge of computer programming or statistics or machine learning and artificial intelligence can get an understanding of data science at high level through this channel. The videos uploaded will not be very technical in nature and hence it can be easily grasped by viewers from different background as well.

Hi Aman, In the last scenario, where Loan Amount = 200, it traverses the left branch. For Id > 2, in the right branch we have 2 records. Here at 6:34, you say both the ID have "Load Status" as Good, so based on Majority voting Good is predicted. What if here Good and Bad are present? How can we predict in this case? Thanks in advance

Really good material, but I think would be even better if you create some more playlists, or a giant ordered playlist. Definitely will make it easier for people to follow the string of videos. :)

@@UnfoldDataScience yes, I'm using those playlists but I can see that many of your amazing videos might not be there, e.g. the ones for logistic regression and decision trees. If I missed them then please let me know.

4:35 What is the reason for taking ID>2? Then at 4:53, you said that we only have 1 ID greater than 2 which is 4 while 3 is also greater than 2. how can you say we only have 1 id greater than 2?

Id doesn’t make sense in this example, should have added a colume like “income” instead

Yes correct, id does not make much sense. Just to keep data set simple I used Id. Thanks for feedback, happy learning!
