AI Beginner Tutorial
AI (Artificial Intelligence) is a technology that enables computers to understand, learn, reason, generate content, and perform tasks.
AI (Artificial Intelligence) is no longer the mechanical operation of fixed programs, but an intelligent technology that can learn from data, make autonomous judgments, and adapt to different scenarios.
In the past, software relied on fixed rules to run, while AI is more like a new form of computing that can learn patterns from data and autonomously accomplish goals.
Today's AI is no longer just a chatbot; it can already: write articles, write code, generate images, analyze data, create PPTs, and more.
Who is this tutorial for?
- Beginners who have never been exposed to AI
- People who want to improve work efficiency
- People who want to enter the AI industry
- People who want to understand concepts such as ChatGPT, large models, and Agent
- Programmers, designers, operations staff, students, and general office workers
No math background required, and no programming skills required.
What can AI do?
AI (Artificial Intelligence) is essentially simulating part of human intelligent capabilities.
- Perceiving information: understanding text, images, speech, video, and various other types of data
- Understanding semantics: comprehending human natural language, needs, scenarios, and implicit logic
- Autonomous learning: continuously optimizing capabilities through massive data training, becoming more accurate with use
- Reasoning and decision-making: analyzing and judging based on available information to provide the optimal solution
- Execution: assisting or autonomously completing tasks such as creation, office work, analysis, and development
An analogy for easy understanding: - Traditional software = calculator: can only calculate by fixed rules, cannot adapt or think
- AI = a smart intern: can learn new knowledge, understand needs, work independently, and keep improving
These abilities, which originally belonged to humans, are now being possessed by computers. We can try using AI tools -- Doubao , and ask it how to learn AI:
AI Core Fundamentals
- Data (foundation): AI's knowledge reserve; massive text, images, video, and behavioral data are the raw materials for AI learning
- Algorithms (rules): AI's "learning methods"; mathematical rules that enable machines to summarize patterns and extract logic from data
- Models (carriers): the finished product after training; intelligent entities that can be used directly (e.g., GPT-4, Claude 3, Tongyi Qianwen)
- Inference (capability): the process after a model goes live, receiving user instructions, combining learned knowledge to output results and complete tasks
AI Categories
Based on functions and scenarios, AI is mainly divided into 5 major categories, covering 99% of ordinary people's usage scenarios:
