Performance optimization tips and best practices

Improving model performance can involve different strategies. Here, we will discuss two main strategies. One strategy is to make changes to the model architecture and observe the results to get any useful insights or indications of improvement. Another strategy could involve exploring the transformation of the target variable. In this section, we will try a combination of both of these strategies.

Log transformation on the output variable

To overcome the issue of significant underestimation of the target variable at higher values, let's try log transformation on the target variable and see whether or not this helps us to further improve the model. Our next model has some...
