Artificial intelligence ppt

  1. 1. ARTIFICIAL INTELLIGENCE
  2. 2. INDEX • ACKNOWLEDGEMENT • History of Artificial Intelligence • Comparisons b/w Human and Computer Intelligence • Categories of Artificial Intelligence • Applications of Artificial Intelligence • Positive and Negative imagination effects of Artificial Intelligence
  3. 3. ACKNOWLEDGEMENT This is to acknowledgement that I, Manik Sharma of class 9th, have made this PowerPoint presentation on the topic “Artificial Intelligence”, which also helped me in doing a lot of Research and I came to know about so many new things.
  4. 4. The modern history of AI can be traced back to the year 1956 when John McCarthy proposed the term as the topic for a conference held at Dartmouth College.
  5. 5. Comparisons b/w Human and Computer Intelligence Normal humans have the same intellectual mechanisms and that differences in intelligence are related to “quantitative biochemical and physiological conditions’, but computer programs have plenty of speed and memory but their abilities correspond to the intellectual mechanisms that program designers understand well enough to put in programs. Whenever people do better than computers on some task or computers use a lot of computation to do as well as people, this demonstrates that the program designers lack understanding of the intellectual mechanisms required to do the task efficiently.
  6. 6. Categories of AI ARTIFICIAL NARROW INTELLIEGENCE (weak AI) ARTIFICIAL GENERAL INTELLIEGENCE (strong AI) ARTIFICIAL SUPER INTELLIGENCE
  7. 7. Applications of AI • Expert systems. • Natural Language Processing (NLP). • Speech recognition. • Computer vision. • Robotics. • Automatic Programming.
  8. 8. Expert systems An Expert System is a computer program designed to act as an expert in a particular domain (area of expertise4). Domain of E.S. Knowledge base Facts Heuristics Phrases in Expert System. Expert systems, not to replace them, They have been used in medical diagnosis, chemical analysis, geological explorations etc. Natural Language Processing (NLP) The goal of NLP is to enable people and computers to LP communicate in a natural (humanly) language (such as, English rather than in a computer language.
  9. 9. Speech recognition The primary interactive method of communication used by humans is not reading and writing, it is speech. The goal of speech recognition research is to allow computers to understand human speech, So that they can hear our voices and recognize the words we are speaking. It simplifies the process of interactive communication between people and computers, thus it advances the goal of NLP. Computer vision People generally use vision as their primary means of sensing their environment, we generally see more than we hear, feel or smell or taste. The goal of computer vision research is to give computers this same powerful facility for understanding their surrounding. Here A.I. helps computer to understand what they see through attached cameras.
  10. 10. Robotics A Robot is a electro- mechanical device that can by programmed to perform manual tasks or a reprogrammable multi functional manipulator designed to move materials, parts, tools, or specialized devices through variable programmed motions for performance of variety of tasks. An “Intelligent” robot includes some kind of sensory apparatus that allows it to respond to change in it’s environment. Automatic Programming Automatic programming is the generation of programs by computer, usually based on specifications that are higher-level and easier for humans to specify than ordinary programming languages. It’s one of the most important part of A.I.
  11. 11. Positive Imagination Maybe, the day is not far when we will just sit back in our cozy little beds and just command our personal Robot’s to entirely do our ruts. He will be a perfect companion for us. Just enjoy the Technology.
  12. 12. Negative Imagination It may end in other way too. Some day there will be a knock at our door. As we open it, we’ll see large number of Robots marching into our house destroying everything we own and looting you. This is because ever since there is an advantage in the Technology, it attracts antisocial elements. This is true for Robots too. Because now they will have full power to think as human, even as of antisocial elements. So we should think trice before giving them power of Cognition.
