8. Building Price Models > Optimizing the Scale

Optimizing the Scale

In this case, it’s not difficult to choose good parameters for scaling because you know in advance which variables are important. However, most of the time you’ll be working with datasets that you didn’t build yourself, and you won’t necessarily know which variables are unimportant and which ones have a significant impact.

In theory, you could try out a lot of numbers in different combinations until you found one that worked well enough, but there might be hundreds of variables to consider and it would be very tedious. Fortunately, if you worked through Chapter 5, you already know how to automatically find a good solution when there are many input variables to consider—by using optimization.
