 * ## Notes
 *
-* -   Downstream consumers of this mapping should **not** rely on specific integer values (e.g., `HINGE == 0`). Instead, the object should be used in an opaque manner.
+* -   Downstream consumers of this mapping should **not** rely on specific integer values (e.g., `EPSILON_INSENSITIVE == 0`). Instead, the object should be used in an opaque manner.
 * -   The main purpose of this function is JavaScript and C inter-operation.

 * @returns {Object} object mapping supported loss functions to integer values
