I'm looking at the answers & I guess it makes sense, but I can't see how I could have arrived at that.

Hi Thrice, yes I got the solution, it took me a while.

My solution is equivalent, basically I update phi(x^(i+1))'theta^(i)

Where ^ is used to denote the index obviously, not "raised to the power of".

If you think about it, the RHS will be computable too.

Just try to get everything into a computable form, ie. get thetas and phis always as part as inner products between themselves.

Let me know if that was helpful, I'll be happy to help more if necessary.
