AI algorithm
Algorithms are very important in the field of artificial intelligence (AI). We need to abstract the actual problems into mathematical problems, and then let the machine solve the mathematical problems. The choice of algorithm directly leads to the ability to solve the problem and how much to solve the problem.

Natural language processing
Natural Language Processing (NLP) is the "translation" between machine language and human language to achieve the purpose of human-computer communication.
Natural language processing includes speech recognition, semantic understanding, and translation of machine language into human natural language.

Computer vision
Computer vision is a study of how to makemachineThe science of "seeing", to a further extent, refers to the use of cameras and computers instead of human eyes to identify, track and measure targets.Machine visionAnd further graphic processing, so that the computer processing becomes an image that is more suitable for human eye observation or transmitted to the instrument for detection.

Voice interaction
Voice interaction is a new generation of interactive mode based on voice input, and feedback can be obtained by speaking. Typical application scenario - voice assistant. Since the introduction of SIRI by iPhone 4S, intelligent voice interactive applications have developed rapidly. Typical Chinese intelligent voice interaction applications such as wormhole voice assistant and Xunfei language point have been recognized by more and more users.
