# Computation about Gaussian and Dirac Delta Function

 P: 692 As far as I can tell from the paper, it seems like either they goofed or the rendering in the pdf file had a problem. I could be wrong, but it seems to me that the two "delta" equations on the fourth page should read: $$p(s|\mathbf{x,w}) = \delta(s - \mathbf{w^T x}).$$ and $$p(y|t)= \delta(y - sign(t)).$$ These interpretations seem consistent with the words that precede each equation. jason
