• 
Keep the
efficiency and simplicity of using a



gradient method
for adjusting the weights, but use


it for modeling
the structure of the sensory input.




– 
Adjust
the weights to maximize the probability



that
a generative model would have produced



the
sensory input.




– 
Learn
p(image) not p(label  image)

If
you want to do computer vision, first learn



computer
graphics



• 
What kind of
generative model should we learn?
