Python Artificial Intelligence Projects for Beginners

Yes
, then the passenger
most likely did not survive. If the answer is 
No
, then it will raise another question: 
Is the
passenger a sibling?
 The following diagram will give you a brief explanation:
Understanding the decision trees does not require you to be an expert in the decision tree
learning process. As seen in the previous diagram, the process makes understanding data
very simple. Not all machine learning models are as easy to understand as decision trees.

Let us now dive deep into decision tree by knowing more about decision tree learning
process. Considering the same titanic dataset we used earlier, we will find the best attribute
to split on according to information gain, which is also known as 
entropy
:
Information gain is highest only when the outcome is more predictable after knowing the
value in a certain column. In other words, if we know whether the passenger is
