4.8. Feature extraction of Text data using Tfidf Vectorizer | Data Preprocessing | Machine Learning

[@srushtimotghare2169]

Why we had not taken title for feature extraction and used title and author?

Just one question, you have posted these vedios before projects..I mean in playlist all vedio till 4.10 lec contains projects stuffs like in this lec also first half part was theory but when it came to implementation you just read code of your project..so why this? Couldn't you have keep projects first, or these vedios later ?

[@sachinvithubone4278]

It's very easy to understand.. thanks

[@Siddhardhan]

Glad to hear that😇

[@Tony-vo9ok]

amazing!!!!!!!

[@ianmuriuki-i8j]

You should have done it separately from the whole spam detection project. Also the dataset provided gives a UnicodeDecode Error when I try to load the csv to the dataframe.

Sir can you please post a video based on feature selection using PSO,bat, algorithm implemented in a tabular dataset with classifier and accuracy.

[@abhilashreddy8028]

what is the diff bw countvectorizer and Tfif Vectorizer

[@Siddhardhan]

refer the following article: medium.com/@wenxuan0923/feature-extraction-from-text-using-countvectorizer-tfidfvectorizer-9f74f38f86cc

[@guided_path56]

this is throwing lower not found error.. why?

[@universal4334]

Bro how to give input ? Do we need to give such values to model as input for prediction ?

[@Siddhardhan]

hi! we can give the texts as input. check out my "Fake News Prediction Project video". you can get more informations on this.... and refer other project videos like diabetes prediction, to understand how to make a predictive system

[@durva2874]

can you plz give smaller dataset so that it becomes easy for downloading

Bro I am stuck on how to set the target label and I don't know which function I have to use and what will be the purpose of this function and what parameters i have to write in that function I still confused brother,i am following your channel from beginning and today I have finished this module but these are the confusion in my mind

[@Siddhardhan]

hi! watch the label Encoding video. it would be useful for you.

[@Greatpretender11c]

Good

[@Siddhardhan]

Thanks

[@pratikpatil956]

we are doing label encoding for converting the output to numerical values.....how we can differentiate between label encoding and feature extraction.

[@vaishalilangote3951]

from where can i get this code?

[@Siddhardhan]

hi! refer the Colab file link given in video description.
