What's the significance of feature "boat" in data for this challenge

#1

Hi
I want to know what’s this feature “boat”, is this life saving boat’s number/tag/name through which passengers got out of ship to save themselves ? I did not know about it’s significance therefore I did not removed “boat” column while performing data pre-processing. Although I got 96% accuracy after submission but I want to know about boat feature significance.
And following is the list of features I removed in data pre-processing [‘name’,‘ticket’,‘cabin’,‘embarked’,‘body’,‘home.dest’] , are there any other unnecessary feature which can be removed to increase accuracy and features which I have removed are right/fine ???

hey @pasta ,
Just by human intelligence you might find that boat feature doesn’t have any significance on this dataset. But might be there be an internal relation of this feature with others or may be with target column.
So for that you need to work highly upon feature engineering techniques as they will help you understand better the data and also find out of there are any relations between features or target and features.

If you are achieving a 96% score , then might be these features are good to be removed. But may be , without removing them you can extract features by combining some features which may help you increase you score.
So it totally depends upon how you experiment on this data. The more you experiment , the more you learn and the more you improve your performance.

I hope this helps you.
