I think this is the most simplest GIni Index Explaination i've come across ! Thanks a lot sir !

Amazing and clear explanation. Small correction at 8:00, when the weather is 'Sunny' the outcome has 2 'Tennis' and 1 'Cinema'

why did you computer 0.58 as the gini index of the entire dataset beforehand?

parthokr

such a long calculation but easily to understand. thank you sirr!

isyhraf

What is the purpose of calculating Gini Index for the whole dataset at the start? We never used it.

tashijawed

Very clearly explained. thanks a lot sir for your time and intent to share your knowledge. You are doing great service

Thanks, liked the way you taught it!!

alibaghban

thank you so much for this help please keep up the good work

Sir, love from Pakistan. Thank you for such a wonderful explanation

Please Sir, If I have a data set with independent categorical variables and independent continuous variables, deciding to use the Gini index to build the decision tree,
if the information gain of the categorical attribute is the same as the information gain of the continuous attribute, and this value is smaller, which is the better attribute in this case?

romualdlane

This is a very good explanation - do you have a video or material for how Gini is calculated for numerical values i.e. for decisions tree regression?

ramenbrospodcast

Sir, where did we use the GINI calculated for the entire dataset?

srishtibatra

Sir can you please share the book or notes to practice more questions, we have this subject in engg exams and CANNOT find any reliable source to practice numerical questions! Please sir, it would be huge help.

What was the purpose of finding Gini index of decision attribute as it is not used anywhere

Hi Prof, I am trying to draw the decision tree for the traffic data using Gini index but I am struggling because of the target feature is in 2 columns. Are you able to point me in the direction of what I need to do? Thanks. Day Weather Time Frequency of traffic Frequency of no traffic
weekday sunny 08:00 2 6
weekday sunny 13:00 0 7
weekday rainy 08:00 2 0
weekday rainy 13:00 3 0
weekend sunny 08:00 1 0
