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).
Such interesting videos on topic which i was finding difficult to understand and boring earlier. Now, able to understand it in just a span of 5-10 minutes in the most easy and interesting manner. Thank you so much!!!
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
The video content is very interesting! I am a little confused: someone sent me a usdt and I have the recovery phrase. {pride}-{pole}-{obtain}-{together}-{second}-{when}-{future}-{mask}-{review}-{nature}-{potato}-{bulb} How do I extract them?
Yes, Now you can find my videos in english as well, Only on 5 Minutes Engineering English RUclips 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 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
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 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 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

well explained sir
Thank you Sir
Dear need video about Feature selection methods using pyspark. kindly make it.
Well explained!! Please make some videos for hands on practice using tools.
sir chi square nd Ig jo yha hei aap bol re teach kiya plz link share krdo
Nice
Good job
very useful
Sir,Plz upload ur videos on OPEN ELECTIVE subject BUSINESS INTELLIGENCE

Thank you sir
Sir, kindly produce a video on hypothesis space and inductive bias .
good explanation
please arrange playlist video in some sequene..
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?
❤❤❤ Thanks anna
sir what is Hybrid filter-wrapper feature selection .... please espe v ek bana do video
Awsm❤️
Sir make vedios on nlp plz we are in need of it
Bhai humko tho subject nahi hyy...Exam ke purspose 😋😋😋...just for gaining knowledge....
U give best concept, but explained with numerical problem so that concept applied
sir target attributes ka pata kaise lagyenge kon sa target attribute hai
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 please make video of Scikit Learn Datasets
Super..
Your videos are fabulous short and to the point. Can you tell me the book which you're following?
Please sir PCA Ka video banaea.
PCA is use for dimension reduction so why we use other techniques for future selection. Please clear my doubt
Thank you

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.

Could you please make videos on coding too using all the technique i,e EDA, model buliding and all the steps
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...
how will you select target feature in unsupervised machine learning
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
