 Loss Functions Objects take 2 forms of inputs:
 
-1. $y\hat$ and $y$ where $y\hat$ is the predicted output and $y$ is the target output.
-2. `model`, `ps`, `st`, `(x, y)` where `model` is the model, `ps` are the parameters,
-   `st` are the states and `(x, y)` are the input and target pair. Then it returns the
-   loss, updated states, and an empty named tuple. This makes them compatible with the
-   [Experimental Training API](@ref Training-API).
