Clipped Double Q-learning

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

Clipped Double Q-learning is a variant on Double Q-learning that upper-bounds the less biased Q estimate Q_(θ₂) by the biased estimate Q_(θ₁). This is equivalent to taking the minimum of the two estimates, resulting in the following target update:

y₁ = r + γmin_(i=1,2)Q_(θ′ᵢ)(s′, π_(ϕ₁)(s′))

The motivation for this extension is that vanilla double Q-learning is sometimes ineffective if the target and current networks are too similar, e.g. with a slow-changing policy in an actor-critic framework.

Papers per year the archive tags with this method, by the paper's archive date (122 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).
