Top 5 advantages and disadvantages of Decision Tree Algorithm
Decision Tree is a very popular machine learning algorithm. Decision Tree solves the problem of machine learning by transforming the data into a tree representation. Each internal node of the tree representation denotes an attribute and each leaf node denotes a class label.
A decision tree algorithm can be used to solve both regression and classification problems.

Advantages:
- Compared to other algorithms decision trees requires less effort for data preparation during pre-processing.
- A decision tree does not require normalization of data.
- A decision tree does not require scaling of data as well.
- Missing values in the data also do NOT affect the process of building a decision tree to any considerable extent.
- A Decision tree model is very intuitive and easy to explain to technical teams as well as stakeholders.
Disadvantage:
- A small change in the data can cause a large change in the structure of the decision tree causing instability.
