Introduction With artiﬁcial neural networks (ANNs) becoming more and more powerful and with the slowdown of complementary metal–oxide–semiconductor (CMOS) scaling, the Von Neumann Viewed 1k times 3 $\begingroup$ I am following an academic lecture on coding theory. Binary multiplication is actually much simpler to calculate than decimal multiplication. They just spelled out all of the details. Authors: CNP Slagle, Lance Fortnow. It's as A.Sh says, being a binary matrix means that the elements are in $\mathbb F_2$ and thus $1=-1$. As stated on the figure, I do not understand how such a simplification (indicated by the red arrow) can be done. @Qwertylicious: If the question you're asking is how do you get $$v_0 + u_0 + u_2 + u_3 = 0$$ that's because $$v_0 = u_0 + u_2 + u_3$$ so $$v_0 + u_0 + u_2 + u_3 = (u_0 + u_2 + u_3) + u_0 + u_2 + u_3$$ which simplifies to zero, since the coefficients get reduced, mod 2. Binary matrix multiplication: finding the number of ones.
