  • Artificial Intelligence in Today's Challenging World
    International Journal of Advance Research, Ideas and Innovations in Technology ISSN: 2454-132X Impact Factor: 6.078 (Volume 7, Issue 3 - V7I3-1809) Available online at: https://www.ijariit.com Artificial intelligence in today’s challenging world Abhishek Negi Mohit Semwal [email protected] [email protected] Uttaranchal Institute of Management, Uttaranchal Institute of Management, Dehradun, Uttarakhand Dehradun, Uttarakhand ABSTRACT Artificial Intelligence refers to any machine that shows feature similar to human mind just like learning and problem solving. AI can take actions that have best chance of solving specific issues in an efficient way. Machine learning is a subset of Artificial Intelligence and refers to the idea of automatically learn and adapt new facts without getting any help from humans. Artificial Intelligence is developing day by day and performing Multitasking and making human work easy and helping human in a fast and efficient ways and gives better solution for complex problems. This paper will describe how AI is helping today’s world and also see what problem is also creating by AI in today’s world. This paper also describe the AI technologies uses in different areas in today world. We also discuss about how AI is useful in many fields but also damaging our environment and the damage is hard to fix and we also get the humans are the main problem. We have to change us to fix a problem. Keywords: Artificial Intelligence, Machine Learning, Humans, Database, Expert System. 1. AI HELPING HUMAN AI assisted robotic surgery is the best example for AI in health sector. It gives positive results are indeed promising.

  • Lisp: Final Thoughts
    20 Lisp: Final Thoughts Both Lisp and Prolog are based on formal mathematical models of computation: Prolog on logic and theorem proving, Lisp on the theory of recursive functions. This sets these languages apart from more traditional languages whose architecture is just an abstraction across the architecture of the underlying computing (von Neumann) hardware. By deriving their syntax and semantics from mathematical notations, Lisp and Prolog inherit both expressive power and clarity. Although Prolog, the newer of the two languages, has remained close to its theoretical roots, Lisp has been extended until it is no longer a purely functional programming language. The primary culprit for this diaspora was the Lisp community itself. The pure lisp core of the language is primarily an assembly language for building more complex data structures and search algorithms. Thus it was natural that each group of researchers or developers would “assemble” the Lisp environment that best suited their needs. After several decades of this the various dialects of Lisp were basically incompatible. The 1980s saw the desire to replace these multiple dialects with a core Common Lisp, which also included an object system, CLOS. Common Lisp is the Lisp language used in Part III. But the primary power of Lisp is the fact, as pointed out many times in Part III, that the data and commands of this language have a uniform structure. This supports the building of what we call meta-interpreters, or similarly, the use of meta-linguistic abstraction. This, simply put, is the ability of the program designer to build interpreters within Lisp (or Prolog) to interpret other suitably designed structures in the language.

E-mail: [email protected] Abstract According to World Health Organization, Cardiovascular diseases are the number one cause of death worldwide. Diagnosing the disease in the right time could lower the danger that it may cause. This paper presents an expert system to assist the General Practitioners (GP) to diagnose any kind of coronary artery diseases. The system supplies the experts with the diagnosing strategies that could be used and suggests the drugs and/or other required operations to be taken alongside with the explanation about the given decision. The design of the system depends on ontology knowledge about the patient’s symptoms to build the knowledge base and then it utilizes Semantic Web Rule Language (SWRL) to deduce the suitable medicine and the required operation for the patient. The system was tested by several GPs using 16 instances to test the validation and the evaluation of the system. Recall and precision factors were calculated 0.83 and 0.87 respectively which considered being reasonable values. 1. Introduction Although medical expert systems are challenging due to huge amount of knowledge and its complexity, the use of these systems witnesses a fast growing in recent years.

    Expert Systems 1 FUNDAMENTALS OF EXPERT SYSTEMS # Bruce G. Buchanan & Reid Q. Smith 1. INTRODUCTION Expert systems are one of the most exciting applications of computers to emerge in the last decade. They allow a computer program to use expertise to assist in a variety of problems, such as diagnosing equipment failures and designing new equipment. They have built on many years of work in artificial intelligence (Al) on problem solving, and have become a' commercially successful demonstration of the power of Al. Correspondingly, by testing current Al methods in applied contexts, expert systems provide important feedback to the science on the strengths and limitations of those methods. In this review, we present the fundamental considerations in constructing an expert system and assess the state of the art. Our discussion focuses on the computer science issues, as opposed to the management or applications issues. 1.1. Characterization and Desiderata Expert systems are distinguished from conventional programs in several important respects. While no single one of the following characteristics is missing entirely from " other well-designed software, all of them together provide a characterization of a distinct class of programs. Suffice it to say that there is not uniform agreement in the literature about any characterization and that few expert systems exhibit all of these characteristics to the same degree. However, the following five characteristics provide a set of desiderata within which we can cluster expert systems. An expert system is a computer program that: a) reasons with knowledge that is symbolic as well as mathematical, b) uses methods that are heuristic (plausible) as well as algorithmic (certain) , c) performs as well as specialists in its problem area, d) makes understandable what it knows and the reasons for its answers, c) retains flexibility.

The expert system is a computer system that emulates the decision-making ability of a human expert, which aims to solve complex problems by reasoning knowledge. It is an important branch of artificial intelligence. In this paper, firstly, we briefly introduce the development and basic structure of the expert system. Then, from the perspective of the enabling technology, we classify the current expert systems and elaborate four expert systems: The Rule- Based Expert System, the Framework-Based Expert System, the Fuzzy Logic-Based Expert System and the Expert System Based on Neural Network. 1.

In the past, in trying to find solutions to problems, AI researchers tended to rely on search techniques or computational logic. These techniques were successfully used to solve elementary or toy problems or very well structured problems such as games. However, real complex problems are prone to have the characteristic that their search space tends to expand exponentially with the number of parameters involved.
