Highest accuracy using NB is 87?

#1

Hi,

I have implemented the code as in the videos in the above section. I have received only 87% accuracy. Can i achieve a higher accuracy for the same?

hey @A18ML0031 ,
I guess with NB 88-90% is the max you can achieve. Though , i guess this max score is achieved by bernoulli NB. So just try that once.
Though to achieve more , you need to work on with different other models , feature engineering techniques , etc.

I hope this helps.

Okay, Thankyou for the same

Hi, I tried the Bernoulli NB and my accuracy reduced to 86%. Do i have to first clean the data. For eg. there are reviews which have a link in them and they have some labels along with them as well. Do we have to remove some of the entries from the train dataset?

I can’t guarantee that it would help to increase your accuracy.
But from an experience in such tasks point of view , cleaning is important. For model to understand the data properly.
But we most times work using the pre trained embeddings , so cleaning works a lot in that but in this case, i dont know.
You can try and experiment on it.
