Artificial Intelligence
(CBR): they use cases to evaluate each input uniquely. Each case would be matched to what a human expert would do in a specific case. Additionally this system knows no right answers, just those that were used in former cases to match. A case library is set up and each decision is stored. The input question is characterized to appropriate features that are recognizable and is matched to a similar past problem and its solution is then applied.
Use of each technology:
Neural networks to predict what stocks are considered to be undervalued given all of the information about the stock at that moment in time (P/E Ratio, Historical Fluctuations, Sector Performance, etc). Neural networks need to be trained on the data before it can predict or learn
Fuzzy logic has many applications that hit close to home. Home appliances win most of the ground with AI enhanced washing machines, vacuum cleaners, and air-conditioners. Hitachi and Matsushita manufacture washing machines that automatically adjust for load size and how dirty the articles are. This machine washes until clean, not just for ten minutes. Matsushita also manufactures vacuum cleaners that adjust the suction power according to the volume of dust and the nature of the floor. Lastly, Mitsubishi uses fuzzy logic to slow air-conditioners gradually to the desired temperature. The power consumption is reduced
Chaos theory it is mainly used in the medical field because of its ability to distinguish between natural and non-natural patterns.
Expert systems are prevalent all over the world. This proven technology has made its way into almost everywhere that human experts live. This can include law, chemistry, biology, engineering, manufacturing, aerospace, military operations, finance, banking, meteorology, geology, and more. Expert systems even can show an employee how to be an expert in a particular occupation. Expert systems have also been applied in medical facilities, diagnosis of mechanical devices, planning scientific experiments, military operations, and teaching students specialized tasks.
Knowledge-based systems and case-based reasoning (CBR) will be on the rise for a long time to come. KBS is finding its home at help desks by working with telephone operators to direct calls. CBR will have close ties to law with its ability to use past precedents to determine a sentence and prison term. KBS is already being used by the Tennessee Department of Corrections for determining which inmates are eligible for parole.
Other fields in which AI is used are:
Genetic programming: it can duplicate human invention by reengineering new solutions to solve
the same problems addressed by state-of-the-art patents.
Image recognition
Describes the state-of-the-art in recognizing images from video. Soon, AI police agents will be able to monitor large crowds.
Logistic planning: America invaded Iraq in operation ‘desert storm’ during which they claimed that they saved more money by using AI logistic planner.
Evaluators
In 1997, Deep Blue an IBM supercomputer defeated world chess champion Garry Kasparov in six games. It was the first time a computer had won a chess match against a current world champion under tournament conditions.
Autonomous agents
In 1999, a NASA AI agent ran a satellite beyond Mars for [next page]
