You can develop an Expert system in many ways. These methods include IF_THEN_ELSE rules (knowledge base), IF_THEN_ELSE Rules (interactive user interface), and knowledge base. In this article, we will discuss the various parts of an Expert System. We will also discuss the work of a Knowledge Engineer to create the Expert System. The knowledge engineer collects and manipulates data. He is responsible for ensuring the Expert System's development and resolving conflicts.
Knowledge base
Expert systems can interpret input and predict the outcome to answer questions. 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. To ensure maximum performance, however, experts must keep their knowledge base current. An expert system can also work in dangerous environments.
IF-THEN-ELSE rules
IF-THEN-ELSE rules are commonly used in an expert system, which is a computer program that interprets input in a given condition and then performs an action. The basic expert system model is based on the knowledge of a single expert, which is mapped to IF-THEN-ELSE rules in the computer program. Ng and Abramson proposed a medical system with multiple experts within a single system. The "Pathfinder system" was built upon multiple experts who could share their knowledge in a single system, when necessary.
Interactive user interface
The interface of an expert system may look similar to the controls and displays on a machine. This gives the user a dual purpose: to use the machine and to provide status information to the expert. This type of interface can help someone in difficult situations. This article will explore the benefits and drawbacks associated with an expert system. The human-computer interaction will also be discussed.
Knowledge base storage
An expert system uses a knowledge base to solve a problem. Expert systems' knowledge bases are populated by facts and rules created by humans. Adding more knowledge to the base will improve the performance of the expert system. Expert systems can not only solve problems but also provide advice and solutions to complex problems. Expert systems can also be used to solve human problems when a human expert has been unavailable.
Knowledge engine
A knowledge engine in AI expert system is a repository of information and rules provided by human experts. The quality of the information will determine the quality of the results. A knowledge engine could be compared with a search engine. It can help you identify common problems and solve them. Human experts however have limited memory and can't remember large amounts of information. A variety of skills and knowledge are available to them, which can make it difficult for them to put all this information together into one answer.
FAQ
Who are the leaders in today's AI market?
Artificial Intelligence (AI), is a field of computer science that seeks to create intelligent machines capable in performing tasks that would normally require human intelligence. These include speech recognition, translations, visual perception, reasoning and learning.
There are many types of artificial intelligence technologies available today, including machine learning and neural networks, expert system, evolutionary computing and genetic algorithms, as well as rule-based systems and case-based reasoning. Knowledge representation and ontology engineering are also included.
There has been much debate over whether AI can understand human thoughts. Deep learning technology has allowed for the creation of programs that can do specific tasks.
Google's DeepMind unit in AI software development is today one of the top developers. Demis Hassabis was the former head of neuroscience at University College London. It was established in 2010. DeepMind invented AlphaGo in 2014. This program was designed to play Go against the top professional players.
What is the role of AI?
An artificial neural network is composed of simple processors known as neurons. Each neuron takes inputs from other neurons, and then uses mathematical operations to process them.
Neurons can be arranged in layers. Each layer has its own function. The raw data is received by the first layer. This includes sounds, images, and other information. Then it passes these on to the next layer, which processes them further. Finally, the output is produced by the final layer.
Each neuron also has a weighting number. This value gets multiplied by new input and then added to the sum weighted of all previous values. If the result exceeds zero, the neuron will activate. It sends a signal along the line to the next neurons telling them what they should do.
This continues until the network's end, when the final results are achieved.
What are some examples of AI applications?
AI can be applied in many areas such as finance, healthcare manufacturing, transportation, energy and education. Here are a few examples.
-
Finance - AI can already detect fraud in banks. AI can scan millions of transactions every day and flag suspicious activity.
-
Healthcare – AI helps diagnose and spot cancerous cell, and recommends treatments.
-
Manufacturing – Artificial Intelligence is used in factories for efficiency improvements and cost reductions.
-
Transportation - Self-driving cars have been tested successfully in California. They are currently being tested around the globe.
-
Utilities can use AI to monitor electricity usage patterns.
-
Education - AI can be used to teach. Students can interact with robots by using their smartphones.
-
Government - AI can be used within government to track terrorists, criminals, or missing people.
-
Law Enforcement – AI is being utilized as part of police investigation. The databases can contain thousands of hours' worth of CCTV footage that detectives can search.
-
Defense - AI is being used both offensively and defensively. Artificial intelligence systems can be used to hack enemy computers. For defense purposes, AI systems can be used for cyber security to protect military bases.
How do AI and artificial intelligence affect your job?
AI will eventually eliminate certain jobs. This includes jobs such as truck drivers, taxi drivers, cashiers, fast food workers, and even factory workers.
AI will create new jobs. This includes business analysts, project managers as well product designers and marketing specialists.
AI will simplify current jobs. This includes accountants, lawyers as well doctors, nurses, teachers, and engineers.
AI will make it easier to do the same job. This includes salespeople, customer support agents, and call center agents.
Which industries are using AI most?
Automotive is one of the first to adopt AI. BMW AG employs AI to diagnose problems with cars, Ford Motor Company uses AI develop self-driving automobiles, and General Motors utilizes AI to power autonomous vehicles.
Other AI industries include insurance, banking, healthcare, retail and telecommunications.
Statistics
- 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)
- According to the company's website, more than 800 financial firms use AlphaSense, including some Fortune 500 corporations. (builtin.com)
- The company's AI team trained an image recognition model to 85 percent accuracy using billions of public Instagram photos tagged with hashtags. (builtin.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)
- 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)
