Reasons for using technology

There are lots of different technology out there today and our reasons for using them differ from technology to technology. But the most common reason for us to use these technologies is for convenience. Since time is moving so fast today we tend to use technology to save time and energy. Another thing is the need. Most technologies today has become standard for everyday lives thus we are forced to learn and use them. Another reason for using technology is for entertainment. Technologies today are not just made to answer are needs but also to entertain us. The last reason maybe is to blend with society and stay updated with the technological developments that happens on a very fast pace.

Introduction

What is Artificial Intelligence?

Defined as the part of computer science concerned with designing systems that exhibit the characteristics associated with human intelligence.

Ultimate goal of Artificial Intelligence research

The ultimate aim is to make computer programs that are capable of solving problems and achieving goals in the world as well as humans.

A.I Today (Where are we now?)

Symbolic A.I systems today are only as smart as the programmer who created it.

Are designed and programmed rather than trained or evolved.

Function under rules and rarely proving effective outside of their assigned domain.

Present Capabilities

Signal processing uses electronic circuitry to detect and convert signals (such as X-ray, ultrasonic, infra-red) into images or sound to aid in signal interpretation. Subtypes include digital signal processing, analogue, audio, speech and video, and signals from arrayed sensors.

Pattern recognition is a branch of artificial intelligence that can assist in recognizing an obscure property from raw input data. A machine capable of pattern recognition can be trained to extract certain features - such as car licence plate numbers - and guide an automated system into making intelligent decisions.

Surveillance systems involve the collection and analysis of data by electronic circuits. The data may enable timely action to be taken with regard to security, border control or the control of a disease.

Decision support systems involve software applications that help analyze data contained within a customized database to support decision-making. This computer technology is used in the management of real estate portfolios, healthcare, cost accounting and budgeting.

Threat and risk analysis applications are electronic-based methods for defining and analyzing threats and vulnerabilities associated with a set of assets or capabilities and supply management with information to develop corrective measures.

System diagnostics use unique signal processing method in a number of industries including metal cutting, machine grinding and materials-handling industries.

A.I Applications

Some AI applications today are as ff.:

Game Playing

Speech Recognition

Understanding Natural Language

Computer Vision

Expert Systems

Heuristic Classifications

Research and Development

Scientist are beginning to look much more on at the mechanisms of the brain an the way it learns, evolves and develops intelligence from a sense of being conscious (Aleksander, 2002).

Trying to develop Artificial Neural Networks (ANN’s). These computational-cognitive-models are designed to exhibit some form of learning and ‘common-sense’ by drawing links between meanings (Hsiung, 2002)

Using Genetic Algorithms in making wise decisions
