Post your queries Here!!
Hello, everyone. I have a few issues regarding project#2. Any help will be greatly appreciated. Here goes:
Q1) A section of the assignment says :
  • Set poverty level of the members and the head of the house within a family."
What does this mean? From my understanding the target variable is the poverty level which can take values 1 to 4. What exactly are we to set therefore?

Q2) Why does the question say to : "
  • Remove null value rows of the target variable", when there are none?

Q3) My Random Forest Classifier gives me an accuracy of around 92% upon cross validation. It does give 99% on the test set so there is slight overfitting. Is this classifier acceptable for this kind of dataset?

Thank you in advance.
