CreateML 训练了什么样的 ObjectDetector Network？

Question

I used CreateML do train a new custom ObjectDector. Everything worked well so far.

Now I am just wondering, what kind of Network is trained in the background? Is it something like YOLO or Mobilenet?

I did not found anything on the official documentation:

Answer 1

There are two options:

1. TinyYOLOv2
2. Using transfer learning. This uses a built-in feature extractor model (VisionFeaturePrint.Objects). This is available with Create ML in Xcode 12.
