Deploy a model
After you create, train, and evaluate a model, you can deploy it. Although it is possible to score a model without deploying it, a model has to be deployed before it can be scored from the Watson Machine Learning APIs. Also, a model can only have a single deployment. For a trial account, a user can have only one deployed model at a time.
When you deploy a model you save it to the model repository that is associated with your Watson Machine Learning service. Then, you can use your deployed model to score data and build an application.
