Diabetes classification submission score

I submitted diabetes classification challenge but my submission score is only 77 %, can u please give me the reason.

Hey,
77 accuracy is kinda good for KNN model, Since this model is the simplest in Machine learning it is also used as a baseline algorithm…
you can try to change the values of K for a better result, it won’t give you very high jump in accuracy.

You will learn about more powerful classification algorithms…

I hope I’ve cleared your doubt. I ask you to please rate your experience here
