Introduced by Ilya Loshchilov et al. in Decoupled Weight Decay Regularization

archive 2025-07-28 Description, source and code snippet are the archive's method entry.

AdamW is a stochastic optimization method that modifies the typical implementation of weight decay in Adam, by decoupling weight decay from the gradient update. To see this, L₂ regularization in Adam is usually implemented with the below modification where wₜ is the rate of the weight decay at time t:

gₜ = ∇f(θₜ) + wₜθₜ

while AdamW adjusts the weight decay term to appear in the gradient update:

θ_(t+1, i) = θ_(t, i) - η(1/(√(v̂ₜ + ϵ))·m̂ₜ + w_(t, i)θ_(t, i)), ∀t

Papers per year the archive tags with this method, by the paper's archive date (206 dated). Bars are counts, not a trend claim.

Components: the archive holds no method-to-method composition, so PwC's Components table cannot be rebuilt; the Papers list carries no Results column for the same reason (the archive does not join its leaderboard rows to method tags).
