+A specialized model that detects faces
+
+Ultra-Light-Fast-Generic-Face-Detector Output Tensors:
+
+| Name          |shape             |
+|---            |---               |
+| [boxes]       |1 x COUNT x 4     |
+| [scores]      |1 x COUNT x 2     |
+
+Where COUNT is a value selected at training time.
+
+# Tensor Decoding Logic
+
+```
+Foreach i in count:
+    X = boxes_processed(i, 0)
+    Y = boxes_processed(i, 1)
+    W = boxes_processed(i, 2)
+    H = boxes_processed(i, 3)
+    S = scores[i][1]
+	If S > threshold:
+		detection_candidates[j++] = [X, Y, W, H, S]
+detections = non_max_suppression(detection_candidates)
+
+```
+
+Where X, Y, W and H are values between 0 and 1. The boxes have been processed
+from the anchors.
