Expert systems
An expert system uses artificial intelligence to simulate the decision-making of a human expert. It contains a knowledge base of rules and facts, an inference engine that reasons about the knowledge, and a user interface. The knowledge base contains declarative and procedural knowledge in a rule-based format. The inference engine derives answers and the user interface allows communication. There are five stages to developing an expert system: identification, conceptualization, formalization, implementation, and testing.
Expert system
An expert system is composed of three main parts: a user interface, a knowledge base, and an inference engine. There are different types of expert systems such as frame-based, hybrid, and rule-based systems. Expert systems offer benefits like completing tasks faster than humans, having a lower error rate, making consistent recommendations, and capturing expertise that may be scarce. They can also be used in hazardous environments unsuitable for people. Expert systems have applications in areas including natural language processing, robotics, computer vision, speech recognition, and machine learning. The typical life cycle of developing an expert system involves problem identification, system design, prototype development, testing and refinement, completion, and maintenance.

The knowledge base contains facts and rules. The inference engine applies rules to solve problems. The user interface allows communication between the user and system. It also discusses the stages of developing expert systems, including identifying the problem, conceptualizing the problem, formalizing it, implementing a prototype, and testing the system. Finally, it lists features of a good expert system such as being useful, usable, and able to explain its advice.
Self learning computer
In computer domain the professionals were limited in number but the numbers of institutions looking for
computer professionals were high. The aim of this study is developing self learning expert system which is
providing troubleshooting information about problems occurred in the computer system for the information
and communication technology technicians and computer users to solve problems effectively and efficiently
to utilize computer and computer related resources. Domain knowledge was acquired using semistructured
interview technique, observation and document analysis. Domain experts were purposively
selected for the interview question. The conceptual model of the expert system was designed by using a
decision tree structure which is easy to understand and interpret the causes involved in computer
troubleshooting. Based on the conceptual model, the expert system was developed by using ‘if – then’ rules.
The developed system used backward chaining to infer the rules and provide appropriate
recommendations. According to the system evaluators 83.6% of the users were satisfied with the prototype.

Lecture 1. Introduction to Expert System.pptx
An expert system aims to emulate human expertise to solve problems that normally require human experts. It consists of a knowledge base that stores facts and rules, an inference engine that applies reasoning to derive solutions, and a user interface for interaction. Expert systems are useful when human experts are unavailable or in high demand. They capture specialist knowledge in domains like medicine, engineering, and oil exploration to make it more accessible.

Expert systems are knowledge-based programs that use specialized knowledge to solve problems in a particular domain. They consist of a knowledge base containing rules and a navigational capability called an inference engine. Knowledge is extracted from human experts and encoded in the knowledge base. The key components of an expert system are the knowledge base, inference engine, knowledge acquisition module, explanation module, and user interface.
Expert Systems
An expert system is an intelligent computer program that uses knowledge and inference procedures to solve problems that require significant human expertise. It emulates the decision-making ability of a human expert in a restricted problem domain. The basic concept of an expert system is that the user supplies facts to the system and receives expert advice in response. Internally, the expert system consists of a knowledge-base containing the expert knowledge and an inference engine that draws conclusions from the knowledge-base.

Expert systems are described as AI programs that store knowledge and make inferences to emulate human experts. The document also outlines the typical components of an expert system, including the knowledge base, inference engine, and user interface. Common AI software mentioned includes CLIPS, Weka, and MOEA Framework.
Design a rule based expert system for eia
Knowledge or Rule based Expert systems systems are widely used in engineering applications and in problem-solving. Rapid development today has brought with it environmental problems that cause loss or destruction of natural resources. Environmental impact assessment (EIA) has been acknowledged as a powerful planning and decisionmaking tool to assess new development projects. It requires qualified personnel with special expertise and responsibility in their domain. Rule-based EIA systems incorporate expert’s knowledge and act as a device-giving system. The system has an advantage over human experts and can significantly reduce the complexity of a planning task like EIA.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
