Gini index based Decision Tree
How does a Decision Tree Work? A Decision Tree recursively splits training data into subsets based on the value of a single attribute. Splitting stops when every subset is pure (all elements belong to a single class) and OMG wow! I'm SHOCKED how easy it was .. No wonder others going crazy sharing this??? Share it with your other friends too! Code for visualising a decision tree - https://github.com/bhattbhavesh91/visualize_decision_tree Please Subscribe!

Decision Tree 3: which attribute to split on?
Full lecture: http://bit.ly/D-Tree Which attribute do we select at each step of the ID3 algorithm? The attribute that results in the most pure subsets. We can measure purity of a subset as the entropy (degree of uncertainty) about the class within the subset.

Let’s Write a Decision Tree Classifier from Scratch - Machine Learning Recipes #8
Hey everyone! Glad to be back! Decision Tree classifiers are intuitive, interpretable, and one of my favorite supervised learning algorithms. In this episode, I’ll walk you through writing a Decision Tree classifier from scratch, in pure Python. I’ll introduce concepts including Decision Tree Learning, Gini Impurity, and Information Gain. Then, we’ll code it all up. Understanding how to accomplish this was helpful to me when I studied Machine Learning for the first time, and I hope it will prove useful to you as well.

Decision Tree - Splitting Criterion & Entropy Calculation | Part-3
The challenge in the decision tree implementation is to identify which attributes do we need to consider as the root node and each level. Attributes selection is important here. We have different attributes selection measures to identify an attribute which can be considered as the root note at each level. Learn the importance of a good splitting criterion and attribute selection measure – entropy. Entropy calculation is explained in detail in the video. Entropy characterizes the purity/impurity of a variable. It’s an indicator of how messy your data is.

Decision Tree Building based on Impurity for KDD or Machine Learning
In this video, I create a decision tree using Gini Impurity to determine the splitting attributes. I originally created this video (and the others in my series) to be used with a specific KDD class which is taught at my home university. I first encountered this algorithm in class there. If you would like to look into this topic in more detail, or read a bit about some similar algorithms, I am including the link to one of the presentations that I used as a reference. coitweb.uncc.edu/~ras/KBS-Class/1-Decision-Trees.ppt Thank you for watching!

Splitting stops when every subset is pure (all elements belong to a single class) -- this can always be achieved, unless there are duplicate training examples with different classes.

How to calculate Gini's co-efficient by Sanjib Mandal  | SanGeotics
The Gini coefficient is a measure of inequality of a distribution. It is defined as a ratio with values between 0 and 1: the numerator is the area between the Lorenz curve of the distribution and the uniform distribution line; the denominator is the area under the uniform distribution line. It was developed by the Italian statistician Corrado Gini and published in his 1912 paper "Variabilità e mutabilità" ("Variability and Mutability"). The Gini index is the Gini coefficient expressed as a percentage, and is equal to the Gini coefficient multiplied by 100. (The Gini coefficient is equal to half of the relative mean difference.)
