Cognitive Science and AI

  1. 1. Cognitive (Science & AI) Saboor Ahmed Awan Batch# 2011-12
  2. 2. Interest development • Masters in Cognitive Artificial intelligence • Hot research area • Utilizing a multi-million dollar investment in technology and science to understand and solve different dimensions of the human side of your most critical problems 
  3. 3. Topic coverage • Artificial intelligence • Cognitive • Cognitive theory • Cognitive science • Cognitive neuroscience
  4. 4. Cognitive and AI as Umbrella • It utilizes our prior knowledge of followings topics for cognitive & AI • Knowledge base • Expert system • Image processing • Data mining • Human behaviors • Robotics • Multiprocessing, multitasking, etc
  5. 5. Cognitive theory • It means thinking and awareness • Cognition is the process by which the sensory input is transformed, reduced, elaborated, stored, recovered, and used. In science, cognition is the mental processing that includes the attention of working memory, comprehending and producing language, calculating,  reasoning, problem solving, and decision making. Various disciplines, such as psychology, philosophy and linguistics all study cognition.
  6. 6. Cognitive science • Cognitive science is the interdisciplinary scientific study of the mind and its processes. It examines what cognition is, what it does and how it works. It includes research on intelligence and behavior, especially focusing on how information is represented, processed, and transformed • The term "cognitive" in "cognitive science" is "used for any kind of mental operation or structure that can be studied in precise terms" (Lakoff and Johnson, 1999). This conceptualization is very broad, and should not be confused with how "cognitive" is used in some traditions of analytic philosophy, where "cognitive" has to do only with formal rules and truth conditional semantics. • focusing on how information is represented, processed, and transformed (in faculties such as perception, language, memory, reasoning, and emotion) within nervous systems (human or other animal) and machines
  7. 7. Cognitive science • “... One major contribution of AI and cognitive science to psychology has been the information processing model of human thinking in which the metaphor of brain-as-computer is taken quite literally. ." AAAI Web pages.
  8. 8. Cognitive neuroscience •  Cognitive neuroscience is an academic field concerned with the scientific study of biological mechanisms underlying cognition, with a specific focus on the neural substrates of mental processes and their biological manifestations. This field addresses the question of how psychological/cognitive functions are produced by the neural circuitry. Artificial Intelligence is defined as the the study of intelligent agents, which is a system that perceives its environment and takes action which maximize its chances of success.
  9. 9. Relationship b/w cognitive and AI • AI can have two purposes. One is to use the power of computers to augment human thinking, just as we use motors to augment human or horse power. Robotics and expert systems are major branches of that. The other is to use a computer's artificial intelligence to understand how humans think. In a humanoid way. If you test your programs not merely by what they can accomplish, but how they accomplish it, then you're really doing cognitive science; you're using AI to understand the human mind • - Herbert Simon: Thinking Machines, from Doug Stewart's Interview, June 1994, Omni Magazin
  10. 10. Applications • Reboots • Drones to deliver goods (amazon use to deliver books via drones) • Wearable devices • Wrist bangles to control crimes in West • Natural language processing • Siri (iPhone app) • Cortana (Microsoft Siri) • Answering machine in call centers, first level support
