Simply put, AI refers to technology that enables computers to take over tasks previously performed by humans for thinking and making judgments. Recently, AI has naturally become a part of our daily lives as it is used in various services such as smartphones, search, video recommendations, and automatic translation.
The simplest definition of AI is that it is a technology designed to enable computers to mimic intelligent human activities such as learning, understanding, and judgment.
AI Key Summary
- AI is a technology that learns patterns through data and makes decisions on its own.
- It can understand and process various types of information, such as text, images, audio, and video.
- It is utilized in various fields such as recommendation, prediction, automation, and content creation.

What is AI? An Easy Definition for Beginners and Seniors
Simply put, AI is a technology that enables computers to perform tasks that previously required human thought and judgment. For example, features such as automatically classifying spam emails or automatically organizing smartphone photos are all examples of AI.
In the past, humans had to manually input all the rules for computer programs. However, AI operates by finding rules on its own through a large amount of example data.
For example, let's assume you are creating a program that recognizes cat photos. In the old way, a human would have had to manually input rules such as "pointed ears," "large eyes," and "whiskers." However, AI learns from thousands of cat photos and identifies the cat's features on its own.
Through this process, the computer becomes able to distinguish objects with increasing accuracy.
AI Understanding with Simple Analogies
The easiest way to understand AI is to compare it to new employee training.
The process by which a new employee at a company learns their job is as follows.
- I look at many work cases.
- Learn what to do in different situations.
- The more experience one accumulates, the more accurately one judges.
AI is similar. It learns patterns by analyzing a large amount of data and generates results for new situations based on that experience.
Core Concepts of AI
To understand AI, you must know a few important concepts. These concepts explain the basic structure of AI technology.
Data
Data plays the same role for AI as experience.
Just as humans learn through experience, AI learns through data. The more data available, the higher the accuracy of the AI.
Representative data types are as follows.
- Photo data
- Text or document data
- Numeric data
- Video data
- Voice data
For example, the Naver Photo app's ability to automatically classify faces is possible because it has learned from a vast amount of face photo data.
Algorithm and Model
In AI, the concepts of algorithms and models are very important.
An algorithm is a method of analyzing data to find patterns. Simply put, it is like a cooking recipe.
For example, the following process is an algorithm.
- Input data
- Analyze data
- Find patterns
- It produces results
A model is the result of training through an algorithm.
In other words, a model can be viewed as an entity akin to a trained employee. When new data is input, the model produces results.
Learning
AI learning is the process of learning rules through data.
Representative learning methods are as follows.
- Supervised learning
- Unsupervised learning
- reinforcement learning
Supervised learning is a method of learning using data with correct answers. For example, it involves training while providing the correct answer, "This photo is a cat.".
Unsupervised learning is a method of classifying data on its own without correct answers.
Recently, a technology called deep learning has become very important. Deep learning is an AI technology that uses large amounts of data to find features on its own.
Inference
Inference is the process by which an already trained model generates results in an actual service.
For example, the following situation is an example of inference.
- If you insert a photo, it tells you, "It is a cat."
- Converts voice input to text
- Enter a sentence and it will show the translation result.
Generation
The most 주목받는 AI feature recently is generative ability.
AI can create new content after learning from existing data.
Representative use cases of generative AI are as follows.
- Writing AI
- Image generation AI
- Music Generation AI
- Code Generation AI
Features such as drafting blog posts or automatically creating images also fall under generative AI.
Key Features of AI
The biggest difference between AI technology and other technologies is that it learns and improves on its own.
automation
AI can automatically handle repetitive tasks.
Representative examples of automation are as follows.
- Spam email classification
- Customer Inquiry Automated Response
- Automatic document classification
- Data cleanup
Companies can significantly increase work efficiency through such automation.
Prediction and Recommendation
AI can predict the future by analyzing past data.
For example, there are services such as the following.
- Shopping mall product recommendations
- YouTube video recommendations
- Weather forecast
- Traffic congestion prediction
Netflix and YouTube recommending videos tailored to users' tastes is also thanks to AI technology.
Personalization
AI learns the different tastes of each person and provides customized services.
For example, there are services such as the following.
- Personalized news recommendations
- Music Recommendation
- Shopping Product Recommendations
- Ad personalization
KakaoTalk news recommendations and Naver news recommendations also utilize personalized AI technology.
interaction
AI can understand human language and converse.
Representative examples are as follows.
- Chatbot
- Voice assistant
- Automatic translation
- Voice recognition service
For example, the feature that automatically sets an alarm when you say "Set an alarm" on a smartphone is also AI technology.
Continuous improvement
The more data AI learns, the better its performance becomes.
By continuously learning from new data, increasingly accurate results can be produced.
