Sir In this challenge when i apply my output it throws error. i am put the output in comma separated format also it throws error please check it.

I guess you would be reading the file using pandas pd.read_csv() function. You need to use sep=’;’, because the values are semicolon separated.

that’s part solve sir but when i will going to upload the output in your solution checker then it throws error

Hello Everyone, sorry for the delay in response and our apologies for the inconvenience caused. We made a few changes to the target variable. Basically, we converted it from string to binary outcome (integer). Request you to re-submit again after making the above changes and it should work normally now.
Target variable:
subscribed: we check whether the client has subscribed to the term deposit or not?

  • 0 implies NOT subscribed
  • 1 implies subscribed

Also, we changed the data from semi-colon separated to comma separated.

Cheers & happy learning!

Even if I am submitting the answer in 0 and 1 format it is giving error as wrong answer. My rows are same as test data rows.

We can see you on the leaderboard now. We hope your issue is sorted

sir again also not submit the file it shows evlaerror as my rows same as your test data row i.e 4509. please solve this sir

Hello sir, I have question regarding to this challenge, in the first try, I tried to implement Standardization for data preparation in order to get the same scala for all of the independent atributes. But, the accuracy is lower than when I didn’t apply it. I am just confused what’s the reason, Sir? Because from what I’ve read, Standardization can increase the performance… Thank you

Hi @nabilah
It depends on the context of data. You cannot apply standardization on any data.

Please go through this thread and a doc given below:
