# What is the inference engine, and why it is used in AI?

What is the inference [engine](https://www.mindstick.com/interview/33775/what-is-a-javascript-engine), and why it is used in AI?

**Definition**:

- An **inference engine** is a software component within an intelligent system that applies logical rules to a knowledge base in order to generate new information.
- The earliest inference engines were part of **expert systems**, which aimed to mimic human expertise by using logical reasoning to solve specific problems.

**Components of an Inference Engine**:

- **Knowledge Base**: The knowledge base stores all the information that the inference engine uses to make decisions. It includes facts, rules, and data related to the problem domain. As new data is added or modified, the knowledge base evolves.
- **Reasoning Algorithms**: These algorithms analyze the data from the knowledge base and apply logical rules to infer new information. Types of reasoning algorithms include deductive reasoning, inductive reasoning, and abductive reasoning.

## Why used in AI:

**Automated Reasoning**:

- An inference engine automates the process of reasoning and decision-making.
- It applies logical rules to available data, allowing AI systems to draw conclusions, make predictions, and solve complex problems.
- Without an inference engine, humans would need to manually analyze data and apply rules, which is time-consuming and error-prone.
