Fixing accuracy problems

In this section, we will look at fixing performance problems through two strategies. The first one involves issues that can be addressed by changing data, and the second strategy involves issues that require restructuring the application. Generally, changing the data is easier, and it is a better strategy if it is important to keep the structure of the application the same – that is, we don’t want to remove classes or introduce new classes. We’ll start by discussing changing the data and then discuss restructuring the application.

Changing data

Changing data can greatly improve the performance of your system; however, you won’t always have this option. For example, you might not have control over the dataset if you work with a standard dataset that you intend to compare to other researchers’ work. You can’t change the data if you are in that situation because if you do, your system’s performance won’...
