Describe the role of bottom-up and top-down processing in developing statistical patterns and using simulation.

Question 2

State two reasons why neural nets have a greater scope than amodal systems.
 
  What will be an ideal response?

Answer to Question 1

Answer: Bottom-up processing of sensory information leads to statistical patterns representations. These representations can later be used in a simulation process to generate mental images and remember past events. Simulation is a top-down process.

Answer to Question 2

Answer: First, statistical patterns can be viewed as neurons or as populations of neurons. Second, an amodal symbol typically represents one category but multiple patterns of a neural net can represent the same category.
