- Gelenter describes the consciousness as the term "QUALIA"
- According to Gelenter, "One person or a thing to be conscious is to have Qualia"
- Gelenter divides AI theories into two camps i.e. Cognitivists & Anti-Cognitivists
- Cognitivist believes if human beings have Qualia, than a robot that behaves like human must have Qualia
- There is no any objective way to tell that whether some entity have Qualia or not
- It distinguishes three level of explanation for any computational mechanism designed to perform an information processing task
- Primary Objective is to make the study the information processing rigorous and give computational theories in AI solid foundations thus eliminating ad-hoc programming solutions and heuristics when building mechanism to perform certain information tasks
Marr's Three Levels of Information Processing :
1) Level - 1 (Computational Level) :
- In this level, It defines What system do and why does it do those things
- It also describes the goal of computation such as why is it appropirate logic of the strategy by which it can be carried out.
2) Level - 2 (Algorithm or Representational level) :
- in this level, it is described how the computation is performed
- It also describes what are the representation for input and output, what is the algorithm for transformation, how these objects and concepts represented, how much space and memory time is required for learning algorithm
3) Level - 3 (Implementation / Physical Level) :
- In this level, it represents how a system can represent the algorith physically
- The type of hardware or machines in which algorith is physically embodied
