1. Intelligence: Intelligence refers to the computer, sensors, the Internet and other technological means, so that the equipment and systems can automatically perceive, analyze and respond to the environment and the user's needs, so as to achieve intelligent control and management. For example, smart home, smart transportation, smart health and so on.

2. Self-learning: AI technology has been able to autonomously learn and continuously optimize its own algorithms and models through machine learning to adapt to different scenarios and needs. For example, deep learning, reinforcement learning, neural networks, etc.

3. Speech Recognition: Speech recognition technology has been able to realize the understanding and processing of natural language, and can be used to control devices or interact through voice commands. For example, intelligent voice assistant, voice translation, voice search, etc.

4. Visual recognition: visual recognition technology can already achieve the understanding and analysis of images and videos, which can be used for face recognition, object recognition, scene recognition, and so on. For example, intelligent security, intelligent transportation, intelligent medical care and so on.

5. Big Data Analytics: Big Data Analytics technology has enabled effective mining and analysis of massive data to provide more accurate and intelligent services and decision support. For example, intelligent marketing, intelligent finance, intelligent manufacturing and so on.

In short, intelligence is mainly embodied in intelligence, self-learning, voice recognition, visual recognition and big data analysis, etc., and these technologies are profoundly changing the way we live and work.
