The Future of Expert Systems in AI: Evolve Technologies And Emerge Applications
Artificial Intelligence (AI) has made remarkable progress in recent years, and expert systems are among the areas expected to grow further. These computer programs can imitate the decision-making skills of a human expert and are utilized in various fields, such as medical diagnosis, financial forecasting, and industrial automation. In this article, we’ll explore the future of expert systems in AI, including technologies and emerging expert systems applications.
Before delving deep into the future of AI expert systems, we first need to understand what is expert systems. Let's start…!
What is Expert Systems and how it works?
Expert systems are computer programs that use artificial intelligence (AI) to simulate the decision-making ability of a human expert. They are designed to solve difficult problems by using sets of knowledge, which are mainly represented as if-then rules, instead of using traditional procedural code.
It typically consist of the following components:
A Knowledge Base: The knowledge base is where the expert system stores information provided by human experts about a particular domain. It also has a knowledge acquisition module that allows the system to gather knowledge from external sources.
An Inference Engine: The inference engine pulls information from the knowledge base to solve problems based on rules. It includes an explanation module that shows users how the system came to its conclusion.
A User Interface: This is how the user interacts with the expert system.
How Expert Systems Work
- Problem Input
The user presents the problem to the expert system through the user interface. This may involve providing specific symptoms, data points, or scenarios related to the problem domain.
- Knowledge Base Access
The inference engine accesses the knowledge base to retrieve relevant facts, rules, and heuristics that pertain to the problem at hand.
- Inference and Reasoning
The inference engine applies the retrieved knowledge to reason through the problem. It may use forward chaining to derive new facts from existing ones or backward chaining to work backward from a hypothesis to find supporting evidence.
- Solution Generation
Based on the inference process, the expert system generates potential solutions or recommendations to address the problem. These solutions may be presented in a ranked order based on their likelihood or effectiveness.
- Explanation and Justification
The expert system can provide explanations for its reasoning and justifications for its recommendations. This allows the user to understand the system's decision-making process and gain confidence in its conclusions.
Expert systems continue to evolve with advancements in artificial intelligence, incorporating techniques such as Machine Learning and Natural Language Processing to enhance their capabilities. They are becoming increasingly valuable tools in various domains and provide expert-level guidance and decision support for complex problem-solving tasks.
Applications of Expert Systems
