NNI provides an easy way to adopt an approach to set up parameter tuning algorithms, we call them **Tuner**.
Tuner receives metrics from `Trial` to evaluate the performance of a specific parameters/architecture configures. And tuner sends next hyper-parameter or architecture configure to Trial.
In NNI, we support two approaches to set the tuner: first is directly use builtin tuner provided by nni sdk, second is customize a tuner file by yourself. We also have Advisor that combines the functinality of Tuner & Assessor.
