Conclusion for Deep Nets
   - Take Home Points
      
	- Deep Nets involve many layers of units.
 
	- There are a range of them, but Hinton's Deep Belief Net is an
            important early example.
 
	- They work on large data sets.
 
	- There are many algorithms used and many different models of
            units.
 
	- Using these, much less developing them, is very complex.
