# Creating Models

A model in Blue Locate and Blue Read is a group of features that appears following a certain pattern. This pattern can be geometrical position (Node Model) or the number of character features that appear glued to each other (String Model in Blue Read). For example, a node model can be a group of 5 features, which form a star formation in terms of their relative geometrical positions. Models are just like labels, so you can consider them a "group label." By creating a model, you define a label consisting of multiple features that appear following a specific pattern in views. Like individual feature labels, the model should be defined and created (labeled) on each view. But the model in Blue Locate and Blue Read is not a neural network and it is not trainable. The model can/cannot be correctly found on each view after processing, and so there can be matched/mismatched models in views.
