TensorFlow Hub hosts models for a variety of tasks. Models for the same task are encouraged to implement a common API so that model consumers can easily exchange them without modifying the code that uses them, even if they come from different publishers.
The goal is to make exchanging different models for the same task as simple as switching a string-valued hyperparameter. With that, model consumers can easily find the best one for their problem.
This directory collects specifications of common signatures for modules in the TF1 Hub format.
