In this section, we will try a couple of things to see whether we can improve the performance of our models. As we have said previously, there are cases where a small improvement in performance could translate to a large impact in the domain of application of the predictive analytics model.
Improving performance
Improving our diamond price predictions
Although we have found the best value of K for a KNN regression model, a neural network still seems a more promising model. To improve the accuracy of our diamond prices predictions, we will do two things:
- Fit a neural network
- Transform the target
