I have a complex math problem that needs solving in my research project
that I don’t have the time to solve.
It will need calculus and differentiation skills.
Let me know if you are interested.
For:
$f(w, b) = \frac{1}{m}\sum_{i = 1}^{m}\frac{\lvert
w^{2}x^{(i)}-w(y^{(i)}-b)\rvert}{cos(tan^{-1}(\frac{y_o^{(i)}}{x_o^{(i)}}))}$
And:
$\frac{y_o^{(i)}}{x_o^{(i)}} = \frac{2w^{2}b -wx^{(i)}+ y^{(i)} +
b}{w^2x^{(i)} - w(y^{(i)} - b)}$
Solve $\frac{\partial{f(w, b)}}{\partial w \partial b} = 0$
For the variables w and b.
$x^{(i)} \text{ and } y^{(i)}$ are each values from one of two different
sets of $m$ real numbers from $i = 1 \text{ to } i = m$.
