Don't we use In-Time validation and Out-Of-Time validation to avoid this ??

Hi Aman, kindly make end to end project video with same train test split in initial state and then performing encoding, handling missing value, outlier basically all feature engineering and selection technique.

How to handle this process when you have text data?
There might be chance of few words present in train and not test.
I faced this problem earlier

Hi Aman

One doubt here did u meant we need to split it beginning itself

Like once we read the dataset we need to split it to train and test even before handling missing values ?
