Freedonia and Asiana, although both are a sample model for LEAP.
To my understanding, the main difference between these two is that Freedonia is meant as training exercise for beginners as well as guiding/reference for all users.
Whereas, Asiana is specifically designed model that is required for LEAP-IBC. LEAP-IBC have specific set of requirements as well as in-built datasets, to run the model and give results.
