Decision Trees: How to Make Predictions using Decision Trees
Decision trees are a type of supervised learning algorithm used for both
classification and regression tasks. They work by recursively splitting the data
into subsets based on the most significant attributes until a stopping criterion
is met. Here's how to make predictions using decision trees:
Data Preparation
.
Prepare the dataset by cleaning, transforming, and normalizing
the data.
Split the dataset into training and testing sets.
.
Feature Selection
.
Choose the features that will be used to split the data.
Measure the quality of a split using metrics such as information
gain or Gini impurity.
.
Tree Growth
.
Grow the tree by recursively splitting the data until a stopping
criterion is met.
