I am new and since my old account was blocked be cause of "offense language" in the username by Gingko100, really guys is h**l such a bad word?

$$  s(x)   =   \frac{1}{1 + e^{-x}} $$

$$    x <^{d} y   \equiv   s(\frac{y - x}{\delta}) $$

$$    if*(p, x, y) \equiv px + (1 - p)y $$

$$ T_o \begin{bmatrix} x \\ y \end{bmatrix} = \begin{bmatrix} -8 \\ -11 \end{bmatrix} $$ $$ T_o \begin{bmatrix} x \\ y \end{bmatrix} = \begin{bmatrix} 2 & -1 \\ 1 & 3 \end{bmatrix} \begin{bmatrix} x \\ y \end{bmatrix} = \begin{bmatrix} 2x -y\\ x + 3y \end{bmatrix} = \begin{bmatrix} -8 \\ -11 \end{bmatrix} $$

$$ \begin{bmatrix} x \\ y \end{bmatrix} $$

$$ \begin{bmatrix} x \\ y \end{bmatrix} = \begin{bmatrix} - \frac{24}{7} & - \frac{8}{7} \\ \frac{11}{7} & - \frac{22}{7} \end{bmatrix}

$$

$$

\begin{bmatrix} x \\ y \end{bmatrix} = \begin{bmatrix} - \frac{24}{7} - \frac{11}{7} \\ \frac{8}{7} - \frac{22}{7} \end{bmatrix} = \begin{bmatrix} -5 \\ -2 \end{bmatrix} $$

$$ T_1 T_2 = \begin{bmatrix} -1 & 0 \\ 0 & 1 \end{bmatrix} \begin{bmatrix} 0 & 1 \\ -1 & 0 \end{bmatrix} = \begin{bmatrix} 0 & -1 \\ -1 & 0 \end{bmatrix} $$

$$ OABC = \begin{bmatrix} 0 & 1 & 1 & 0\\ 0 & 0 & 1 & 1 \end{bmatrix} $$

$$ T_2 T_1*OABC = \begin{bmatrix} 0 & 1 \\ 1 & 0 \end{bmatrix} \begin{bmatrix} 0 & 1 & 1 & 0\\ 0 & 0 & 1 & 1 \end{bmatrix} $$ $$ = \begin{bmatrix} (0*0) + (1*0) & (0*1) + (1*0) & (0*1) + (1*1) & (0*0) + (1*1) \\ (1*0) + (0*0) & (1*1) + (0*0) & (1*1) + (0*1) & (1*0) + (0*1) \end{bmatrix} $$

$$ = O_{21}A_{21}B_{21}C_{21} = \begin{bmatrix} 0 & 0 & 1 & 1 \\ 0 & 1 & 1 & 0 \end{bmatrix} $$
