424 B
- Randomly
- Gaussian noise with mean = 0
- Small network
- Fixed sigma is fine
- 0.01
- E.g. 8 layers
- AlexNet
- Fixed sigma is fine
- Too large
- Wont converge
- Too small
- Gradient wont propagate back many layers
Xavier System
\sigma=\frac 1 {n_{in}+n_{out}}or
\sigma=\sqrt{2/n}- Where
n=\text{filter size}\times n_{out} - And
n_{in}andn_{out}refer to number of image channels in and out of the layer
