## How do you create a decision tree for classification?

Basic Divide-and-Conquer Algorithm:

1. Select a test for root node. Create branch for each possible outcome of the test.
2. Split instances into subsets.
3. Repeat recursively for each branch, using only instances that reach the branch.
4. Stop recursion for a branch if all its instances have the same class.

## What does an entropy of 1 mean?

Entropy is measured between 0 and 1. (Depending on the number of classes in your dataset, entropy can be greater than 1 but it means the same thing, a very high level of disorder.

## What is decision tree explain with diagram?

A decision tree is a flowchart-like diagram that shows the various outcomes from a series of decisions. It can be used as a decision-making tool, for research analysis, or for planning strategy. A primary advantage for using a decision tree is that it is easy to follow and understand.

## What is simple decision tree?

A Simple Example Decision trees are made up of decision nodes and leaf nodes. In the decision tree below we start with the top-most box which represents the root of the tree (a decision node). After splitting the data by width (X1) less than 5.3 we get two leaf nodes with 5 items in each node.

## What is decision tree and its types?

Decision trees are used for handling non-linear data sets effectively. The decision tree tool is used in real life in many areas, such as engineering, civil planning, law, and business. Decision trees can be divided into two types; categorical variable and continuous variable decision trees.

## What is the difference between a classification tree and a decision tree?

The primary difference between classification and regression decision trees is that, the classification decision trees are built with unordered values with dependent variables. The regression decision trees take ordered values with continuous values.

## How do we classify trees?

The starting point for most people when identifying trees species is the leaves. There are three basic leaf types: needles, scales and broadleaf. Most evergreens have needles or scales, while most broadleaf trees are deciduous, meaning they drop their leaves when dormant. However, there are exceptions.
