Clipped gaussian distribution

WebFor example, [16, 18] have noted that the dot-products of (1) tend to have a symmetric, non-sparse distribution, that is close to Gaussian. Taking into account the fact that ReLU is a half-wave rectifier, this suggests the use of the half-wave Gaussian quantizer (HWGQ), ... the clipped ReLU is a better match for the HWGQ than the vanilla ReLU.

This occurs when w (z) has increased to √2 w 0. Using Equation 4, the Rayleigh range (z R) can be expressed as: (5)zR = πw2 0 λ z R = π w 0 2 λ. This allows w (z) to also be related to z R:
