2007 NIPS Tutorial on: Deep Belief Nets
<>1 vihj i j i j t = 0 t = 1 "=(<>0!<>1) wij#vihj vihj Start with a training vector on the visible units. Update all the hidden units in parallel Update the all the visible units in parallel to get a “reconstruction”. Update the hidden units again. This is not following the gradient of the log likelihood. But it works well.

Kernel Descriptors for Visual Recognition
rse-lab.cs.washington.eduThe hard binning underlying Eq. 1 is only for ease of presentation. To get a kernel view of soft binning [13], we only need to replace the delta function in Eq. 1 by the following, soft –(¢) function: –i(z) = max(cos(µ(z)¡ai)9;0) (4) where a(i) is the center of the i¡th bin. In addition, one can easily include soft spatial binning by
