+
+This criterion decorates a `criterion` by allowing the `input` and `target` to be
+fed through an optional `inputModule` and `targetModule` before being passed to the
+`criterion`. The `inputModule` must not contain parameters as these would not be updated.
+
+When `castTarget = true` (the default), the `targetModule` is cast along with the `inputModule` and
+`criterion`. Otherwise, the `targetModule` isn't.
