    Artificial intelligence Artificial intelligence Presentation Transcript

    • Artificial intelligence
      Presented by Bharath. P
      Information science
      Sapthagiri college of engineering
      Bangalore.
      Creativity corporation
    • What is AI ?
      Branch of computer science that deals
      with intelligent behavior, Learning and
      adaptation in machines.
      John McCarthy

    • Creativity corporation
      Research fields in AI
      • Deduction, reasoning and problem solving
      • Knowledge representation
      • Planning
      • Learning
      • Natural language processing
      • Motion and manipulation
      • Perception
      • Social intelligence
    • Deduction, Reasoning and Problem solving
      Implementing the problem solving technique which
      we all use naturally, How does our brain solve problems ,
      what is the procedure it follows to Solve it.
      Example: Let there be a picture puzzle i.e. re arranging
      pieces of a picture Now , how does our brain know that this
      piece comes in this place only, How does it solve this.

      Knowledge representation
      Knowledge can be considered as huge database of all things present in this world, environment(our surroundings). Each and every action requires knowledge.
      We call this knowledge as common sense, which we all use it all the time.
      There is an obstacle in front of u while walking , u walk carefully avoiding it. Its common sense, how do u implement all these in a machine.
    • Creativity corporation
      Planning
      Machines must visualize future and must be able to predict about how their actions will change surroundings. They must have a representation of the world in them.
    • Creativity corporation
      Learning
      Machines will be made to learn and get their knowledge. Learning can be done in 2 ways
      • Supervised learning: learning process will be under the control of developer of machine.
      • Unsupervised learning: learning process is a continuous one in the lifetime of machines.
    • Creativity corporation
      Natural language processing
      This gives machine ability to read and understand the languages that human speak. They can take the input of natural language either by reading or listening to what humans speak and also can respond in same language.
    • Creativity corporation
      Motion and Manipulation
      Robotics is very closely related to AI. This field i.e. motion
      and manipulation is used in robotics, intelligence is required
      to handle tasks such as object manipulation and navigation.
      Robots move around and also displace objects.
    • ASIMO
      It is a humanoid robot created by Honda. Standing at 130 centimeters (4 feet 3 inches) and weighing 54 kilograms (114 pounds), the robot resembles a small astronaut wearing a backpack and can walk or run on two feet at speeds up to 6 km/h (4.3 mph)

    • Creativity corporation
      Perception
      It is the ability to use input from sensors
      (cameras, microphones, SONAR etc)
      This field also includes
      • speech recognition
      • Facial recognition
      • object recognition
    • Creativity corporation
      Social intelligence
      Machines showing emotions and behaving socially
      like us is social intelligence. It must react politely and
      be sensitive to humans.
    • Creativity corporation
      General intelligence
      Combination of all the skills told till now matching
      human abilities or even exceeding it is
      called general intelligence. A perfect artificial human
      being.
    • Creativity corporation
      Approaches to AI
      Methods and ways used to solve these AI problems
      • cybernetics
      • cognitive simulation
      • logic based
      • anti logic or scruffy
      • knowledge based
      • sub symbolic
      • statistical
    • Creativity corporation
      Cybernetics
      It is the study of control and communication in the animal
      and machine. Simulation human brain
    • Creativity corporation
      Cognitive simulation
      Psychology was the base of this approach to AI.
      Human psychology was simulated
    • Creativity corporation
      Logic based
      This approach uses formal logic to solve a wide variety
      of problems, Including knowledge representation, planning
      and learning. programming language used is PROLOG
    • Creativity corporation
      Knowledge based
      Expert systems were developed keeping knowledge as the base,
      these systems could behave like an human expert and
      answer or provide solutions to any questions related to that field
      to which it is intended.
    • Creativity corporation
      Sub symbolic approach
      This included solving difficult problems in vision and natural
      language processing, methods used here were not simple
      principles like logic.
      • neural networks
      • fuzzy systems
      • evolutionary computation
      are some of the fields involved in sub symbolic approach.
    • Creativity corporation
      Statistical
      This used sophisticated mathematical tools to solve specific
      sub problems. Measurable and verifiable results were obtained
      from this approach.
      operations research (OR) field is included here.
    • Creativity corporation
      Tools
      Tools used for AI to the approaches mentioned are
      • Search and Optimization
      • Logic
      • Probability methods of uncertain reasoning
      • neural networks
      Neural networks
    • Creativity corporation
      Applications
      • Finance : banks can use AI to organize operations , invest in stocks and
      manage properties
      • Medicine : AI technique is employed to generate a sequence of operations
      understandable by the control system of a robot
      which is to perform a semi-automatic surgical task
      • Heavy industry : Robots can do jobs which are dangerous to humans.
      It can be used to do very repetitive jobs which may lead to
      mistakes or accidents due to lapse in concentration.
      • Transportation : Cars have automatic gearboxes, its doing job of a human
      its also considered to be part of AI , fuzzy logic controllers
      are used to develop it.
      • Toys and games :Robot pets , super toys etc.
      • Military : spy robots , unmanned bombers , advanced aircrafts …
    • Creativity corporation
      Care-providing robot friend
      The care-providingrobot FRIEND uses sensors like cameras and intelligent
      algorithms to control the manipulator in order to support disabled and
      elderly people in their daily life activities.
    • Kismet
      A Robot designed to assist research into social interactions between robots and humans
      Creativity corporation
    • TOPIO
      This robot can play table tennis
      Creativity corporation
    • Creativity corporation
      Future - Andriods
      A complete bio-mechanical human is possible.
      Humans can themselves be implemented with micro chips
      And/or genetically altered as to be just as high as robots.
