Learning Objectives: 
  • Define a homomorphism as a mathematical property
  • Evaluate existing systems to determine whether they are adequate representations
  • Assess the data quality needed for a new application to be successful
  • Recognize the advantages and disadvantages of using models to study and manage the world as opposed to experimenting in the world directly
  • Describe the ways in which an existing model faithfully represents reality and the ways in which it does not
