You need to create a custom AI Builder model. 
What model types can you use to create a custom model?

Answer options:

A.Prediction
B.Object detection
C.Key phrase extraction
D.Category classification
E.Sentiment analysis

Correct Answers: A, B and D 
AI Builder provides prebuilt and custom models in three categories: Text, Prediction, and Vision. 
You can train the following model types: Text category: Category classification and Entity extraction
Prediction category: Prediction
Vision category: Form Processing, Object Detection
Three of these types don’t have prebuilt models: Prediction, Form Processing, Object Detection. The other two, Category classification and Entity Extraction, have both model types — prebuilt and custom. 
Several models have only the prebuilt type, such as Key phrase extraction, Sentiment Analysis, Business card reader, and others. Options C and E are incorrect because Key phrase extraction and Sentiment Analysis are prebuilt models only.
