The Role of Decision Tree in Data Mining
Branches of possibilities and outcomes
We all make decisions in life depending upon the possibilities and possible outcomes. The track of all these possibilities and outcomes take the form of a tree metaphorically. The role of Decision Tree in Data Mining is tremendous. Read a brief account of this important current topic in data science.
What is decision Tree?
To decide on a process execution one goes through various possibilities of decisions, this leads to the formation of decision tree. The possibilities are “Yes(Y)”, “No(N)” or “either/or”. For example on a cross road there are two possibilities either left or right road. If left road taken then what will be the result and if right road is taken what will be the result. The decision making may change the outcomes. One can also predict the decision making process of that passenger if he has been following passenger for long through his decisioning analysis.
One can then make a visual map of all decisions taken by explicitly representing all moves. Visual map is a tree like representation of decision model
