What is the main function of the Cache folder in the DU framework?

The Cache folder in the DU (Data Unification) framework serves an important role in managing the test results within the system. Its main function is to save expected results for tests, which allows the framework to compare actual outcomes against these expected results during testing processes. This capability is crucial for validating the performance and accuracy of machine learning models, ensuring that any deviations from the expected outcomes are correctly identified and addressed.

The correct answer highlights the significance of maintaining a repository of anticipated results, which facilitates thorough testing and iteration on models. By storing these benchmarks, the Cache folder enhances the efficiency of the development and testing workflows in the DU framework.
