*ANSWER* HW5-Q5: E(u,v) derivatives

[IsidroHidalgo]

My iterations go extremely slowly, so I suspect having an error in my derivatives. Can someone take a look to them and see if all is ok? Thank you:

u = u - learning.rate*2*(u*exp(v)-2*v*exp(-u))*(exp(v)+2*v*exp(-u))
v = v - learning.rate*2*(u*exp(v)-2*v*exp(-u))*(u*exp(v)-2*exp(-u))

The derivatives are correct. Please check your code again.

Got it: I was calculating v with the updated u. It's vital to update both in one step...
