Conclusion
   - Take Home Points:
     
       - Binary classifiers are important.  
 
       - Many classifiers  can be implemented by lines or hyper-planes.
 
       - These can be learned.  
 
       - You can test your learning algorithm wtih an N-Fold test.  
 
     
    
   - Reading:  For this lecture you can look at the 
       
       Binary Classification wiki , and the
       
       Linear Classifier wiki .
       
 
   - Reading for next week:  read Russell and Norvig 18.1 through 18.3 (pp 704 - 718)
