EDGE FDE
IntermediateFrom the metal to the model
Start at Metal shaders. Walk the clothing-classifier stack backwards until you return to the original pipeline lesson.
For people who finished, or quickly looked through, PyTorch to Core AI in Xcode.
Lessons
Key concepts
- This course walks backwards from Metal and Apple silicon up to the original pipeline.
- The contract is
clothing.aimodel, functionmain,image[1, 1, 28, 28]float32 0-1,logits[1, 10]. - Core AI can run on CPU, GPU, or Neural Engine. Metal is how the GPU runs work.
- Each layer above must give the layer below shapes, types, supported ops, and prepare once.
Takeaways
- You can read the clothing classifier from the chip up, not only from training down.
- When something breaks, ask which lower-layer requirement failed before you blame the UI.
- You can reopen the original pipeline and read every forward arrow as a requirement for the layer below.
