Why isn’t this formula used at all?
$$ w_{n+1} = w_n - \alpha \frac{f \nabla f}{||\nabla f||^2} $$
It calculates where the line that’s in the same direction as gradient and has $f$’s slope in that direction becomes zero.
In one dimensio …

Why doesn’t this optimization method work?
My idea is simple, for a loss function $L$, learning rate $\alpha$ and weights $W_n$ define the function $u_n(\alpha)$ as:
$$u_n(\alpha) = L(W_n - \alpha \nabla_n L)$$
If we find the minimum of $u_n$, …
