You will define artificial intelligence (AI) differently, depending on whether you're interested in the realities of AI, or dramatization in movies and novels. AI technology is capable of many amazing things, and is a major part of our everyday lives, but has no emotion or internal motivation.
Fiction and AI
Fictional accounts of artificial intelligence and robotics tend to lend human characteristics, such as fear or anger, to the computer running the AI algorithm. In reality, however, an algorithm is just a set of instructions for solving a problem.
The confused and conflicted computers that are so interesting on television and at the movies are not realistic, or even likely, given the limitations of today's technology. When a computer processor runs an AI algorithm, it simply goes through the instruction set, and follows the commands to reach the desired result - there are no emotions involved in the process.
Artificial Intelligence Terms
Discussions of technology, such as AI, is typically sprinkled liberally with jargon, or high-tech terms that are unintelligible for anyone who isn't already an expert in the topic. Here are a few common terms that you need to understand, in order to get familiar with AI.
- Artificial Intelligence -- Computer programs that can simulate or replace human thought, including decision-making abilities, are considered artificially intelligent.
- Machine Learning -- The process by which an algorithm improves its ability to function through learning by example, through direction, or by trial-and-error.
- Neural Networks -- Computing systems that increase their processing power by networking huge numbers of small processors together to mimic the human brain's neural networking.
- Fuzzy Logic -- A simulated version of human common sense, using if-then statements to tell the computer what to do, and when to do it. A simple example of fuzzy logic: A thermostat is set to maintain a steady temperature of 78 degrees Fahrenheit. When the temperature gets too hot, it turns the air conditioner on to cool the room. When the room is sufficiently cooled, it turns the air conditioner back off.
- Semantic Web -- The ability of search engines to use algorithms to "understand" the actual meaning of a string of words, through the use of context and other clues.
Define Artificial Intelligence
AI is a complex technology, but understanding the terms used to explain the uses of AI can help you acquire basic knowledge of the various applications, without the confusion that comes along with the excessive use of jargon.
