+## Usage
+
+```javascript
+var resolve = require( '@stdlib/ml/base/sgd-classification/loss-function-resolve-str' );
+```
+
+#### resolve( value )
+
+Returns the loss function string associated with a supported SGD classification loss function value.
+
+```javascript
+var str2enum = require( '@stdlib/ml/base/sgd-classification/loss-function-str2enum' );
+
+var v = resolve( 'hinge' );
+// returns 'hinge'
+
+v = resolve( str2enum( 'hinge' ) );
+// returns 'hinge'
+```
+
+If unable to resolve an SGD classification loss function string, the function returns `null`.
+
+```javascript
+var v = resolve( 'beep' );
+// returns null
