Introduced by G. Zhang et al. in Effectiveness of Scaled Exponentially-Regularized Linear Units (SERLUs)
archive 2025-07-28 Description, source and code snippet are the archive's method entry.
SERLU, or Scaled Exponentially-Regularized Linear Unit, is a type of activation function. The new function introduces a bump-shaped function in the region of negative input. The bump-shaped function has approximately zero response to large negative input while being able to push the output of SERLU towards zero mean statistically.
SERLU(x)) = λₛₑᵣₗᵤx if x ≥0 SERLU(x)) = λₛₑᵣₗᵤαₛₑᵣₗᵤxeˣ if x < 0
where the two parameters λₛₑᵣₗᵤ > 0 and αₛₑᵣₗᵤ > 0 remain to be specified.

Usage over time archive 2025-07-28
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).
