Column Transformer in Machine Learning | How to use ColumnTransformer in Sklearn

[@ameerrace2284]

Why have you used fit_transform for test? Shouldn't it be only transform?

[@campusx-official]

Yes it's a mistake. Sorry about that

[@okonkwo.ify18]

Nope. U fit_transform the data that’s going to be fitted into d model.

[@GamerBoy-ii4jc]

or kch ni pta but Sir apki videos ny meri zindgi zroor mentos bna di. Thanks alot Sir! for this hard work.

why you stopped man come back and keep it going buddy

[@prashantmalik5333]

bro, your teaching skills are extra ordinary ... I'm in love with ML because of you... I wonder why your channel isn't on the top while suggesting ML videos .. I think the GOOGLE algorithm needs to improve 🤣 Once again thanks for your videos.

[@11aniketkumar]

Thank god, I came across this channel. This channel is a hidden gem. Thanks a lot sir.

[@kshitiztiwari9275]

Bhai you are good. Specially for we Indians... We know English But Hindi main its so Good and Your content is perfect. Just Perfect. Kudos.

Good part about your videos is that you not only show the solution but also focus on the pain areas which brings the necessity of a solution.

best content ever💯

[@nikcru]

Beautifully explained... Liked & Subscribed. :)

[@rohitmadke8407]

Very well explained... Best resource on youtube... but i have major doubt!! why dont you apply all transformation to data and then split it... why are you splitting it first and then performing transformation?

[@alkalinebase]

Thankyou so much. It was crystal clear and to the point for a beginner like me.

[@saurabhbarasiya4721]

great explanation .........

[@kunalpandya8468]

For Aam zindagi section, you used fit_transform for X_test also... It should be only transform na..

[@Enjoyurlife1789]

Yes he committed his mistake in above comments.

[@whitepanda95]

😅 Really can be more thankful, you are reason, I feel confident that, I will crack machine learning and also learn upto LLM else I would had drop my transition altogether, thank you very much for motivating me. Already bought course, hope all people also support you with same. 🎉

sir please make more videos on column transform with more categorial columns...💯👍🙏🙏

kudos to you man!!

[@jayshreedonga2833]

NICE LECTURES THANKS

[@deepanshudutta4443]

Sir one confusion,after using columntransformer we get numpy array,when we convert it into dataframe,we get column names like 0,1,2,....how we rename the column name? Because there are lots of column...

[@shubhamgosain4534]

Thank you sir

[@arjunsingh-dn2fo]

sir, can we apply this before train_test_split ?

[@motivationalfacts4964]

What if we have missing values in numeric column and other one has Categorical column? Could we use simple imputer for two times one as for using mean and other one for MODE for handling the categorical missing values?

[@eeshananand3773]

Sir their is a bit mistake you made in your code when i went through github, without using column transformer, when the algorithm were applied in each column, the fit_transform was used in both the training dataset as well as the testing dataset but this is wrong because out test datasets is based on the training dataset, so we cant impose fit_transform function on test dataset based on test dataset

[@calvinfernandez-hi6ij]

I have this question as well as to why are we doing fit_transform on testing data. Should'nt we just be doing transform

[@namirkhan8515]

Great Vid

[@yashjain6372]

bhai best

[@readbhagwatgeeta3810]

What is the difference in using np.hstack and using np.concatenate? 🤔

[@mdyounusahamed6668]

I would like to thank you for making such awesome videos. But here, you used the fit_transform() method with the test dataset. Isn't it transform()?

[@tejaskamble8731]

No he fit_transform only training data 14:57

[@AbdulRahman-zp5bp]

Thanks you 3000 🙂

[@tusarmundhra5560]

Sir, please make a complete tutorial on Machine Learning Algorithm

[@hassamkafeel]

resulting array from column transfer is not in same order as of dataframe, right? why?

I like the Mentos Zindegi😅

[@purushottammitra1258]

In 14:53 why not fit_transform is used with xtest??

[@campusx-official]

Because it is already fitted with the training data

sir can't we use label encoding in gender because we only have two types. male and females, just like you said email classification as spam and non spam? answer = NO, because label encoding is done on y axis and not on x i.e on output and not input

[@maza.tu.h]

Column names are not shown after column transformation. Any solution for this?

[@prathamsaboo]

Anyone getting concatenation error? all the input array dimensions except for the concatenation axis must match exactly, but along dimension 0, the array at index 0 has size 20 and the array at index 1 has size 80

[@ronylpatil]

Sir columns get shuffled when we do column transformer. Is there any impact of this?

[@MUHAMMADAHMAD-c7m]

What is logic behind multicollinearity, and you drop='first'

Bhaiya m is series ko complete to kr lunga but kya as a associate professional y mujhe help krega??

[@mahender2517]

just one small doubt, would be great if anyone can clear. Why to train test split first and then do column transform separately for both train and test sets.We can also first transform the sets and then split the set into train and test

[@rolitrivedi3190]

Simply because train test split should always be done before any transformation. Test data is something we should not see beforehand otherwise the result may not be right
