You built a regression model and it's yielding a very low R-Squared value. What could be the reason and how would you improve it?

  • Data noise; Apply data cleaning
  • Incorrect model; Change the model
  • Poorly fitted; Improve the model fit
  • Too many features; Reduce features
A low R-Squared value might indicate that the model doesn't fit the data well. This could be due to an incorrect choice of model, underfitting, or other issues. Improving the model fit by selecting an appropriate algorithm, feature engineering, or hyperparameter tuning can address this problem.
