Excellent tutorial. But, regarding embedded method.. (as per my understanding) the algorithm itself filter the unimportant feature. The best example is regularization. Ridge and Lasso regularization in liner regression remove or vanish the unimportant feature coefficient (As their coefficient is already low and after applying regularization it will become zero).

Very nice explanation..short and compact..i love the way u make us understand...I am so happy after watching your video that I subscribed your channel to learn more from you
Yes, Now you can find my videos in english as well, Only on 5 Minutes Engineering English UA-cam Channel. This is a new youtube channel and I am trying my best to provide Computer Science topics in english but It may take some time to cover all CS topics.
Sir Nyce explaination...But recersive feature,does that take reverse also...for eg SAY ABC THEN AB,AC,AD...BUT WILL IT TAKE REV ALSO LIKE IF AB THEN BA ALSO,IF AC THEN CA ALSO,IF DA THEN DA ALSO AND SO ON..OR TAKE 3 LIKE ABC THEN ACB,BAC,BCA,CAB,CBA AND SON ON DEPENDING ON THE ROW LENGTH...PLS ANSWER ASAP
Hello, Thanks for the explanation. I have one question. My question is, Does using best features helps to reduce the training data sets. Say I do not have a large datasets, but I can make independent variable that is highly corelated with the dependent variable, will it help me reduce my traning data sets. Your response will be highly valuable.
what is the difference between PCA and Feature selection? because both serve the purpose of selecting useful information or getting rid off the overfitting problem, isn't it?
sir your videos r really good... i get the best results to the topics here.. but I want to request more videos... there r a lot more topics in ML which u haven't completed... so just help me there... i am from RTU kota. my university have some unexpected works on this course... i mean the topics r not sequential and all.. in some bad way only.. help me please...
Sir in practical i have 80000 fratures for each image. Say Such 500 images are there. So the dimension is 80000*500. Now i have to apply pca for dimensionality reduction. But nowhere i find the technique. Please help me.
Sir variable selection methods multiple regression me Jo h us par video banwaye I.e forward, backward and stepwise selection method in multiple linear regression Jo h
Sir but i do bigmart sales prediction model In this model if i take only revelant attribute and if i take all the attribute then i found more number number of attribute gives more accurate prediction .please help me out

aree sir ji thanks i will comment after todays paper >>>>>>>>>
Watching this video before exam , its very much helpful
Excellent.. one.. this is first video ... i saw.. and it 100% give me understandings...
Watching lecture before exact 13 min of exam😅😅
Same condition 😂
Make a video on Feature Extraction Method with Examples
Watching from Pakistan
Sir your explanation giving deep learning of ML Thankuuuuuuu
Your explanation is very easy to understand...
Excellent tutorial
bhaiji please 10th march tak machine learning cover krlo...sirf numericals bhi chalenge
Really amazing dear...
Thanks a lot for your dedication...
Really it is appreciable!!!
Bhaiya me ek hi like kr sakta hu baki apke sab video k 100 likes bante h, obviously me mere groups me share kruga
bhai you deserve more subscribers
Please let me know can we use any of these techniques in an unsupervised learning Clustering problem where there is no target variable
dude you have make it so interesting hats off

Sir plz upload the video of 2-3 unit of machine Learning.... exam he sir plzzz
very good way for understanding a topic
Very nice explanation.. In a very easy manner..
What an explanation... Hats off
Sir just once do AES and DES encryption
Ple explain this topic :
Matlab method
Neural network toolbox and fuzzy logic toolbox
Unsupervised learning neural network
Simple implementation. Of artificial neural network and fuzzy logic
Please upload video on Data scaling and Normalization.
But decision tree is a classic example of overfitting model. So how can you say that embedded is better wrapper method in terms of overfitting?
Awesome explanation!
PCA is use for dimension reduction so why we use other techniques for future selection. Please clear my doubt
Great explain sir 😃😄,
Finally got good resource to me for learne ML in simple and easy way 😊
Sir Thanks a lot for your help.. i have watched, shared and liked every video.. :)
please upload more videos of Machine Learning...

ultimate bhai.very nice explanation, n method to teach
Superb teaching
Thank you sir thanks a lot you helped lot of people like me thank you very much
sir chi square nd Ig jo yha hei aap bol re teach kiya plz link share krdo
Sir Fantastic....Sir aap please python bhi lo sir...
what is the difference between PCA and Feature selection?
because both serve the purpose of selecting useful information or getting rid off the overfitting problem, isn't it?
i think in pca u dont remove the features , you simply project them into lesser no of dimensions while maintaining 85% variance atleast.
In which case we shud use filter methods...
U give best concept, but explained with numerical problem so that concept applied
very useful
Wow good explanation
Is feature selection problem correlated with regression...?
sir your videos r really good... i get the best results to the topics here.. but I want to request more videos... there r a lot more topics in ML which u haven't completed... so just help me there... i am from RTU kota. my university have some unexpected works on this course... i mean the topics r not sequential and all.. in some bad way only.. help me please...
please arrange playlist video in some sequene..
Sir Aap excellent ho. Sir aap python pay machine learning sikhaye please please
