Need help on excersie 4 of c3w2 assignment

[benvuong]

I am stuck on the 4th exercise of the c3w2 assignment where we would prepossess the text and labels using the map and lambda functions. I tried to following the other exercises and just can’t seem to get it.

When using dataset.map, it’s okay to return a tuple of type (processed text, processed label). Use the label encoder just the way you use the text vectorizer to create the mapped dataset.

Hi @benvuong

see that if this explanation helps

C3W2 Expected output

In the preprocess data, basically there are 3 call arguments already assigned for this grade cell. one is dataset for you to preprocess next text_vectorizer which is function recall to convert your text data into vector and lastly label_encoder which you recalled in the previous grade cell will be used to encode data labels here in this cell, preparing your preprocess data to be model trained. You need to define this in single code line using map keys( ) to the argument dataset. Hope this r…

make sure while you create the lambda text, don’t forget to tuple the text and labels when using their respective function call.
