fu, fn: Factor vectors for u and n. The dot product of these vectors is intended to describe the “ideological agreement” between a user and a note. These vectors are currently one dimensional, though the algorithm is in principle agnostic to the number of dimensions.
It took me a few minutes to figure out that “one dimensional” appears to mean “the vector contains one number”.

Thanks for pointing that out. I’ve added some clarification.
