Influence of Artificial Intelligence on Communication Systems

Influence of Artificial Intelligence on Communication Systems

An invited talk at Snow & Avalanche Study Establishment Research & Development Center (SASE RDC), Chandigarh, on April 16, 2008, by R C Chakraborty, Visiting Prof. JIET, Guna & Former Dir. DTRL & ISSA (DRDO). The Highlights of my talk :

(a) Timeline of Telecommunication related technology – Telegraph, Morse code, Telephone Exchange, Wireless telegraphy, Iconoscope, Television system, Radio networks;

(b) Timeline of Artificial Intelligence related technology – Roman Abacus, Pascaline, Diff. Engine, Boolean algebra, Turing machines, Von Neumann architecture, ENIAC;

(c) Timeline of AI events – Turing test, intelligent behavior, Logic Theorist, Birth of AI, General Problem Solver, LISP language, DoD’s Advanced Research projects, Micro-world program SHRDLU, Expert systems, Computer vision, Prolog ;

(d) Modern digital communications – geosynchronous communication satellites, packet switching theory, wide-area computer network, Optical fiber, Internet era, ARPANET, Birth of login – ‘log’ ‘in’, Protocol – TCP/IP, Internet;

(e) AI vocabulary – Intelligence, Intelligent behavior, knowledge is collection of facts, Learning is what facts or behaviors represent, Knowledge Model – a degree of connectedness & understanding that increase, we progress from data to information to knowledge and to wisdom;

(f) Building Intelligent Communication Systems – Seamless global network, Intelligent mobile platform, Voice-recognition across Mobile-phone, and Knowledge base Networking;

(g) Conclusion – We live in an era of rapid change, moving from information to knowledge based seamless global intelligent network of society.  The creation of intelligence in machine has been a long cherished desire to replicate the functionality of the human mind. Intelligent information and communications technology (IICT), emulates and employ some aspect of human intelligence in performing a task. The IICT based systems, include sensors, computers, knowledge-based software, human-machine interfaces and other devices. Today, intelligent systems applications exists virtually in all sectors where they deliver social as well as economic benefits.

Artificial Intelligence – Knowledge Representation – issues, predicate logic, rules

Artificial Intelligence – Knowledge Representation, Issues, Predicate Logic, Rules

This is part of the courseware on Artificial Intelligence, by R C Chakraborty, at JUET. It consists eight hours of lectures. The topics are :

Knowledge Representation (KR) – introduction, knowledge progression, model, category, typology map, relationship, mapping, representation, schemes, relational, inheritable, inferential, declarative, procedural, attributes, relationship, granularity.

KR using Logic – predicate logic, propositional logic, statements, variables, symbols, connective, truth value, contingencies, tautologies, contradictions, antecedent, consequent, argument, expressions, quantifiers, formula, representing “IsA” and “Instance” relationships.

KR using Rules – declarative, procedural, meta rules, procedural verses declarative knowledge & language, logic programming characteristics, statement, language, syntax & terminology, data components, simple & structured data objects, program components clause, predicate, sentence, subject, queries, programming paradigms, model, computation, imperative model, functional model, logic model, reasoning, forward and backward chaining, conflict resolution, and control knowledge.
