ELU: negative-saturating exponential neural activation

Contribution grade

Neural-network activation functions · Human-designed research method or resource

Reference score120,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Combined positive identity responses with a negative saturating exponential branch to study activation centering, bias-shift effects and deep-network optimization.

Scientific scope

Combined positive identity responses with a negative saturating exponential branch to study activation centering, bias-shift effects and deep-network optimization. General image-learning method despite author institute name; not a biological result. Inherits rectifiers, leaky/PReLU and centering/natural-gradient ideas. Conditional bias-shift analysis and empirical classification gains do not prove that all gradients avoid vanishing or every task benefits; exact zero means are not guaranteed.

Evidence
