AI and C programming
I was having a chat with a friend of mine who have been working in software projects in Europe for a while now. Currently, he has been handling projects that make use of AI. As part of AI programming, one would require to write scripts. My friend informed me that most of these scripts (as well as other recent programming languages) uses concepts and structures borrowed from C language. So there, folks, never underestimate the importance of learning C language in your programming class. The profound impact Dennis Ritchie has had on modern computer science have been greatly undervalued till now, what do you think? ….

AI QUIZ 2
Q1. Which subjects have influenced developments in ArtificiaI Intelligence?
Some of the influences in AI came from diverse fields such as
(ii) Pattern Recognition
(iv) Cognitive Science
(vi) Building Fast computers
(vii) Mathematics, Probability and Statistics
(x) Control Theory
(xii) Data mining
(xiii) Data warehousing
(xiv) Advances in data acquisition devices and technologies (wearable computing etc.)
(xv) Internet (web data)
(xvi) Swarm Intelligence
(xvii) Bio Inspired Computation
(xviii) Data Structures
Q2. How do we know whether a system is intelligent or not?
The answer to the question is to be found in the famous Turing Test named after the great Computer Scientist Alan Turing. Turing devised a mechanism in which a human interrogator is kept in a separate adjacent room from a person and a computer. The walls of separation wouldn’t enable the interrogator to peep inside the other room housing the person and the machine. If the computer manages to converse/answer intelligently fooling the interrogator making him unable to vouch convincingly whether the replies has come from the computer or the person, then we can say that the computer has passed the Turing Test, and that it qualifies as an Intelligent system.
Q3. What is an agent? Explain with an example
An agent is something that can perceive the environment by sensors and act upon it through actuators e.g., a vacuum cleaner agent – as soon as it senses dirt in the environment, it performs the cleaning action by sucking through its pump (actuators).
Q4. What is searching? Why are searching techniques required? Explain with an example
Searching means to find the required item/data from a store of data containing relevant and irrelevant data… searching techniques are the techniques used by us to search the same. Searching techniques are needed to make the searching process efficient and time saving due to large amount of availability of data. Searching techniques are of two types:
(i) Uninformed or blind search – Breadth First Search, Depth First Search …
(ii) Informed Search – (Heuristic based ) Best First Search, AO* …
Q5. What is meant by Natural Language Processing? Give an example of an NLP system
Natural language processing means that the computer is able to understand, analyze and act upon the environment passed to it through human speech, text or video in normal human languages such as English e.g., a robotic waiter that is able to understand orders given to it by the customer in different human languages.
On the other hand, the goal of AI is to make a machine behave like a human, even incorporating human traits of ineptitude (like taking sufficient time like a human for solving mathematical calculations involving big numbers). KBS has no such restrictions of human like behavior, it draws upon human expert knowledge and builds upon it for better performance in real-life problem solving. In a sense, KBS may be viewed as an application area of AI.
Some definitions/pioneering thoughts on Artificial Intelligence
In Computer Science, work termed “AI” has traditionally focused on the high-level problem; on imparting high-level abilities to “use language, form abstractions and concepts” and to “solve kinds of problems now reserved for humans” (McCarthy et al. 1955)
AI is the science of making computers do things that require intelligence like humans (Minsky)
The automation of activities that we associate with human thinking, activities such as decision making, problem solving, learning … (Bellman, 1978)
Physicists ask what kind of place this Universe is and seek to characterize its behavior systematically. Biologists ask what it means for a physical system to be living. We (in AI) wonder what kind of information processing system can ask such questions – Avron Barr and Edward Feigenbaum (1981)
The fundamental goal of this research is not merely to mimic intelligence or produce some clever fake. “AI” wants the genuine article; machines with minds – John Haugeland (1985)
AI is the study of mental faculties through the use of computational models – Eugene Charnaik and Drew McDermott (1985)
We call programs ‘intelligent’ if they exhibit behaviors that would be regarded intelligent if they were exhibited by human beings – Herbert Simon
AI is the study of techniques for solving exponentially hard problems in polynomial time by exploiting knowledge about the problem domain – Elaine Rich
The art of creating machines that perform functions that require intelligence when performed by people (Kurzweil, 1990)
The study of the computation that make it possible to perceive, reason and act (Winston, 1992)
AI … is concerned with intelligent behavior in artifacts (Nilsson, 1998)
Computational Intelligence is the study of the design of intelligent agents (Poole et al., 1998)
AI is a branch of computer science concerned with the study and creation of computer systems that exhibit some form of intelligence: systems that learn new concepts and tasks, systems that can reason and draw useful conclusions about the world around us, systems that can understand a natural language or perceive and comprehend a visual scene, and systems that perform other types of feats that require human types of intelligence (Dan W. Patterson)
