Connectionist networks

Last updated Dec 25, 2021 Edit Source

• Seed

• architecture
  • large number of units which are connected to others (connectionism) and the connections have different strengths (weights)
  • units are arranged in layers
  • computation happens in parallel
• like in a classical machine, representations are assigned to connectionist networks by the people who build them
• two types of connectionist representation
  • localist → each unit is assigned a feature as a whole that represents
  • distributed → state of the network as a whole represents something
    • often claimed to be one of the distinctive features of connectionism
    • connectionist networks is sometimes called parallel distributed processing (PDP)
• can be trained to learn
• resemble the structure of the brain much more closely than any classical computer
  • really good at pattern recognition
