Researchers Isolate Why the Muon Optimizer Reaches Grokking Faster Than AdamW
A new analysis separates spectral-norm constraints from orthogonalized momentum to identify the mechanism actually responsible.
A paper on arXiv, titled "The Active Ingredient in Muon's Grokking," revisits an observation that the Muon optimizer reaches the grokking threshold on modular arithmetic faster than AdamW, meaning the model transitions from memorization to…
