Transcript

  • 1. A Life
    Artificial Life Overview
    Created for Models of Learning and Instruction taught by Dr. Cafolla
    Group Members: David Manset and Jaclyn Clark
  • 2. What Is A Life?
    Artificial Life: “is a field of study and an associated art form which examine systems related to life, its processes, and its evolution through simulations using computer models, robotics, and biochemistry.”
    Spectrum of Artificial Life
  • 3. Definition
    “Artificial Life is the name given to a new discipline that studies ‘natural’ life by attempting to recreate biological phenomena from scratch within computers and other ‘artificial’ media. A life complements the traditional analytic approach of traditional biology with a synthetic approach in which, rather than studying biological phenomena by taking apart living organisms to see how they work, one attempts to put together systems that behave like living organisms.- Chris G. Langton
    Artificial Life has initiated unprecedented alterations to society and science with aspects of living organisms that cannot be categorized as quite human.
  • 4. Developers seek to…
    create real, carbon-based living organisms and behaviors such as:
    Growth
    Adaptation
    Reproduction or Self replication
    Socialization
    Learning
    Death
    But artificial life still seeks to:
    survive without the input complicated proteins, or other large molecules, or life sustaining elements
    evolve and adapt over time through a natural selection process
  • 5. Three types
  • 6. Wet: Biochemistry
    This area is an attempt to stimulate origin of life with self-replicating and self-producing efforts.
    In Vitro method is when and experiment is given in a controlled environment outside of a living organism
    Example
    Chemical Substrates: molecules to which an enzyme acts
  • 7. Real Examples
  • 8. Second Life-One Example of Artificial Life
    Second Life® is a 3-D virtual world created by its Residents. Since opening to the public in 2003, it has grown explosively and today is inhabited by millions of Residents from around the globe.” (from http://secondlife.com/whatis/)
  • 9. Early Contributors of Artificial Life
    John McCarthy
    coined Artificial Intelligence
    "the science and engineering of making intelligent machines.”
    Craig Reynolds
    In 1987 created familiar flocking behavior in groups of computer-designed "boids" like birds
    Used these rules for behvaior
    separation: steer correctly to prevent crowding
    alignment: steer in direction of other flockmates
    cohesion: steer to move toward the approximate position of local flockmates
    Provided a forerunner to computer animation
    Many scientists, mathematicians, professors, researchers, and intellectuals contributed to development of artificial life forms before computers even existed. Adjacent are a few men and their significant contributions.
  • 10. Contributors
    Alan M. Turing
    Artificial Intelligence Pioneer
    Wrote “The Chemical Basis of Morphogenesis” in 1951
    Machine intelligence: technology could be installed with intelligence the same way routine tasks were programmed
  • 11. More Contributors
    John Von Neumann
    Termed “automaton" as any machine which behaved logically by joining environmental information with the machine’s own programming
    Claimed machines would self-replicating
    Machines would be logical and not necessarily requiring physical bodies
  • 12. Practical Uses
    Social Networking
    Provides links to connect people with similar interests
    Interacting with gamers at the same skill level
    Education
    Allow study of living creatures vs. technology created life
    Use of computer for analytical thinking
    Many games replicate the movement pattern of organism groups in an interactive way for students
    Simulators provide first hand experience over description of a process
    Art
    3 dimensional life like and enhanced images
    Fantasy and highly detailed images created and saved in computer storage (RAM)
