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).

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...
Yes, Now you can find my videos in english as well, Only on 5 Minutes Engineering English CZcams 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.
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.
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
That line "Aaj ka video bahut hi kamal ka hone wala hai"..😄
Sir aapka har video kamal ka hota hai..😀
Watched you when I did my Bachelor's, watching you now when I'm doing my Master's!

The best channel i have found so far for my data mining course. 100/100
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
Sir ji itne dino se kaha the aap ab to Engineering bhi khatam hone wali h ,,, pahle hi mil jate 👍👍
Aik dam baraber bhaiyya, Aik dam baraber.
jabardast bhai...thanks to teach in interacive way....kamaaal ka enthusiasm he apka
Your explanation delivery is too good... people connect with u ... Good stuff mate.
Excellent tutorial
aree sir ji thanks i will comment after todays paper >>>>>>>>>
Sir Thanks a lot for your help.. i have watched, shared and liked every video.. :)
please upload more videos of Machine Learning...
Watching this video before exam , its very much helpful
I think out of 3.80 lakh subscribers,3.70 lakh subscribers are the ones who study one day before the exam😂😂😂.You are a genius.Thank you .
Excellent.. one.. this is first video ... i saw.. and it 100% give me understandings...
Sir just once do AES and DES encryption
Make a video on Feature Extraction Method with Examples
dude you have make it so interesting hats off
Great explain sir 😃😄,
Finally got good resource to me for learne ML in simple and easy way 😊
Really amazing dear...
Thanks a lot for your dedication...
Really it is appreciable!!!
Sir plz upload the video of 2-3 unit of machine Learning.... exam he sir plzzz

Thanks a lot sir❤❤
Wow good explanation
Sir,Plz upload ur videos on OPEN ELECTIVE subject BUSINESS INTELLIGENCE
ultimate bhai.very nice explanation, n method to teach
Dear need video about Feature selection methods using pyspark. kindly make it.
Nice
Please let me know can we use any of these techniques in an unsupervised learning Clustering problem where there is no target variable
U give best concept, but explained with numerical problem so that concept applied
Thank you
Well explained!! Please make some videos for hands on practice using tools.
Thank you sir
vai, so good you are.......
good explanation
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?
Good job
Great explanation!!
Sir, kindly produce a video on hypothesis space and inductive bias .
Bhai humko tho subject nahi hyy...Exam ke purspose 😋😋😋...just for gaining knowledge....
Thanks
Sir make vedios on nlp plz we are in need of it
❤❤❤ Thanks anna
Sir Fantastic....Sir aap please python bhi lo sir...
Sir ur teaching style is very good ...but can u please teach the content in English so a normal people can also understand 😊
Sir Aap excellent ho. Sir aap python pay machine learning sikhaye please please
Please sir PCA Ka video banaea.

Sir please make video of Scikit Learn Datasets
well explained sir
Super..
sir chi square nd Ig jo yha hei aap bol re teach kiya plz link share krdo
sir please Machine Learnig playlist sort your playlist beacause it create confusion many videos are there in different different places
AES AND DES plz
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
PCA is use for dimension reduction so why we use other techniques for future selection. Please clear my doubt
sir what is Hybrid filter-wrapper feature selection .... please espe v ek bana do video
Thank you so much sir.. For clear explanation of every concept of ml.. Your videos helps a lot in insem exam of be
Could you please make videos on coding too using all the technique i,e EDA, model buliding and all the steps
Very Nice ....!
You're super enthusiastic.
I liked it
