Learning, Classification and Lines
 
   - Learning is both what makes people intelligent, and
       
 
   - the key to modern AI.
 
   - We know a lot about how people learn, but there is also
       a lot we don't know.
 
   - There are a lot of jobs in Big Data and Data Analytics, and this
       makes such extensive use of machine learning, that we can
       also call them machine learning. 
 
   - One simple class of AI systems classifies things; they're called
       classifiers. 
 
   - These classifiers can often be learned.
 
   - A simple version of these are binary classifiers.
 
   - Classifiers often separate the data based on a line.
