Builtin-Tuners
==============

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 configuration. Tuner sends the next hyper-parameter or architecture configuration to Trial.
