Anyone here know how this can be transformed into a telescoping series? c^(k) is a counter that goes from 1 to K, w(k) is a vector of weights initialized as <0,0,..0>, x is a vector of inputs with same length as w(k) and b is a bias scalar.

Does this have something to do with the sign operator being -1 during updates?

>c^(k) is a counter that goes from 1 to K
you mean c(k) = k?

yes, that's exactly it.
