LUIS Train - microsoft-campus-community/workshop-shopping-list-bot GitHub Wiki
Prerequisite: This page assumes that you have a LUIS Application created. If you do not have one yet, follow the steps to build a LUIS application first.
You have defined Intents and Entities by giving LUIS example sentences of them. Now it is time to make LUIS learn from them. By training LUIS, it will classify intents and entities of sentences we have not provided to it directly.
You need to retrain LUIS every time you make changes to the intents or entities.
You start training LUIS by clicking on the 'Train' button in the upper right corner. 
Wait until you see the 'Train completed' notification. 
Good! Now LUIS is trained on recognizing our intents and entities even if we give it sentences that it does not know.
