There are many methods to create an Expert System. These include IF-THENELSE rules, knowledge bases, IF-THENELSE rules and an interactive user interface. This article will cover the different parts of an Expert Systems. We'll also discuss how a Knowledge Engineer works to develop the Expert System. The knowledge engineer collects and manipulates data. He monitors the development of the Expert System and resolves conflicting rules.
Knowledge base
An expert system is able to interpret input and predict the result. These systems can answer queries by interpreting input and predicting the outcome. They are more reliable than human experts. Experts' output is free from errors because they take into account all information. This is unlike human experts who can make mistakes due to emotional charges. An expert system's knowledge base must be maintained to maintain its optimal performance. Expert systems can be used even in potentially hazardous situations.
IF-THEN-ELSE rules
IF-THENELSE rules are used frequently in expert systems, which are computer programs that interpret input and perform an action. The expert system model's base is based on one expert's knowledge, which is mapped into the computer program using IF-THENELSE rules. Ng and Abramson proposed a medical system with multiple experts within a single system. The "Pathfinder” system was based upon multiple experts who could pool their expertise into one system when needed.
Interactive user interface
An expert system's user interface could look very similar to the machine's controls. This allows the user to both operate the machine and gather status information for the expert system. This kind of interface can be used to help a person in difficult situations. In this article, we will discuss the advantages and disadvantages of an expert system. Further, we will explore the use of a human-computer interface.
Knowledge base storage
An expert system relies on a knowledge database to solve a problem. A knowledge base for an expert system contains facts and rules collected by human experts. The performance of an expert system will improve if there is more information. Besides solving problems, expert systems can advise human beings on a particular topic and solve many complex tasks. Expert systems can assist humans with solving complex problems even when a human expert cannot be reached.
Knowledge engine
A knowledge engine, an AI expert system, is a repository of rules and information that has been provided by human experts. The more information you provide, the better your results will be. A knowledge engine is similar to a search engine. It is great in helping to identify and solve common problems. Human experts, on the other hand, have limited memory and are unable to retain large amounts of information. They also have many skills and knowledge, making it hard to combine all the data into one answer.
FAQ
What does AI mean today?
Artificial intelligence (AI), a general term, refers to machine learning, natural languages processing, robots, neural networks and expert systems. It's also called smart machines.
Alan Turing wrote the first computer programs in 1950. He was fascinated by computers being able to think. He proposed an artificial intelligence test in his paper, "Computing Machinery and Intelligence." The test asks whether a computer program is capable of having a conversation between a human and a computer.
John McCarthy, in 1956, introduced artificial intelligence. In his article "Artificial Intelligence", he coined the expression "artificial Intelligence".
Many AI-based technologies exist today. Some are easy to use and others more complicated. They can range from voice recognition software to self driving cars.
There are two main categories of AI: rule-based and statistical. Rule-based AI uses logic to make decisions. To calculate a bank account balance, one could use rules such that if there are $10 or more, withdraw $5, and if not, deposit $1. Statistical uses statistics to make decisions. A weather forecast may look at historical data in order predict the future.
Is Alexa an Artificial Intelligence?
Yes. But not quite yet.
Amazon has developed Alexa, a cloud-based voice system. It allows users to interact with devices using their voice.
The technology behind Alexa was first released as part of the Echo smart speaker. Other companies have since used similar technologies to create their own versions.
Some examples include Google Home (Apple's Siri), and Microsoft's Cortana.
What are some examples AI applications?
AI is being used in many different areas, such as finance, healthcare management, manufacturing and transportation. Here are just a few examples:
-
Finance - AI has already helped banks detect fraud. AI can scan millions upon millions of transactions per day to flag suspicious activity.
-
Healthcare - AI can be used to spot cancerous cells and diagnose diseases.
-
Manufacturing – Artificial Intelligence is used in factories for efficiency improvements and cost reductions.
-
Transportation - Self Driving Cars have been successfully demonstrated in California. They are now being trialed across the world.
-
Utilities are using AI to monitor power consumption patterns.
-
Education - AI is being used for educational purposes. For example, students can interact with robots via their smartphones.
-
Government - AI is being used within governments to help track terrorists, criminals, and missing people.
-
Law Enforcement - AI is used in police investigations. Search databases that contain thousands of hours worth of CCTV footage can be searched by detectives.
-
Defense - AI can both be used offensively and defensively. It is possible to hack into enemy computers using AI systems. For defense purposes, AI systems can be used for cyber security to protect military bases.
What is AI and why is it important?
It is predicted that we will have trillions connected to the internet within 30 year. These devices include everything from cars and fridges. The Internet of Things is made up of billions of connected devices and the internet. IoT devices are expected to communicate with each others and share data. They will also have the ability to make their own decisions. For example, a fridge might decide whether to order more milk based on past consumption patterns.
It is anticipated that by 2025, there will have been 50 billion IoT device. This is a tremendous opportunity for businesses. However, it also raises many concerns about security and privacy.
How will governments regulate AI?
While governments are already responsible for AI regulation, they must do so better. They need to ensure that people have control over what data is used. Companies shouldn't use AI to obstruct their rights.
They should also make sure we aren't creating an unfair playing ground between different types businesses. A small business owner might want to use AI in order to manage their business. However, they should not have to restrict other large businesses.
What can you do with AI?
Two main purposes for AI are:
* Prediction – AI systems can make predictions about future events. For example, a self-driving car can use AI to identify traffic lights and stop at red ones.
* Decision making-AI systems can make our decisions. So, for example, your phone can identify faces and suggest friends calls.
Who was the first to create AI?
Alan Turing
Turing was born in 1912. His father, a clergyman, was his mother, a nurse. He excelled in mathematics at school but was depressed when he was rejected by Cambridge University. He took up chess and won several tournaments. After World War II, he was employed at Bletchley Park in Britain, where he cracked German codes.
He died in 1954.
John McCarthy
McCarthy was born on January 28, 1928. He studied maths at Princeton University before joining MIT. He created the LISP programming system. In 1957, he had established the foundations of modern AI.
He died in 2011.
Statistics
- In 2019, AI adoption among large companies increased by 47% compared to 2018, according to the latest Artificial IntelligenceIndex report. (marsner.com)
- More than 70 percent of users claim they book trips on their phones, review travel tips, and research local landmarks and restaurants. (builtin.com)
- A 2021 Pew Research survey revealed that 37 percent of respondents who are more concerned than excited about AI had concerns including job loss, privacy, and AI's potential to “surpass human skills.” (builtin.com)
- While all of it is still what seems like a far way off, the future of this technology presents a Catch-22, able to solve the world's problems and likely to power all the A.I. systems on earth, but also incredibly dangerous in the wrong hands. (forbes.com)
