Table 2 Summary of dimensions for the output layer

size{p(m)}

p(m) = z^i-1(m)⇒ size{p(m)} = S^i-1× 1

size{W(m)}

L × S^i-1

size{v(m)}

L × 1

size{z(m)}

$\mathit{z}\left(m\right)=\widehat{\mathit{x}}\left(m\right)\Rightarrow \mathsf{\text{size}}\left\{\mathit{z}\left(m\right)\right\}=L\times 1$

size{e(m)}

$\tilde{L}\times 1$

size{r(m)}

size{D _a } = 2U × L⇒size{r(m)} = 2U × 1

and size{Ω} = 2U × 2U

size{δ(m)}

L × 1
