NNI (Neural Network Intelligence) is a toolkit to help users run automated machine learning (AutoML) experiments. The tool dispatches and runs trial jobs generated by tuning algorithms to search the best neural architecture and/or hyper-parameters in different environments like local machine, remote servers and cloud.
Those who want to try different AutoML algorithms in their training code (model) at their local machine.
Those who want to run AutoML trial jobs in different environments to speed up search (e.g. remote servers and cloud).
Researchers and data scientists who want to implement their own AutoML algorithms and compare it with other algorithms.
ML Platform owners who want to support AutoML in their platform.
