# webui

NNI is a research platform for metalearning. It provides easy-to-use interface so that you could perform neural architecture search, hyperparameter optimization and optimizer design for your own problems and models.
Web UI allows user to monitor the status of the NNI system using a graphical interface.

## Deployment

### To start the webui

> $ yarn
> $ yarn start

## Usage
