What is a digital human and what does the future hold?
In today's technologically advanced world, lifelike digital humans have become an emerging field that has attracted much attention. As a digital virtual image that is close to the human image created based on computer graphics (CG) technology and artificial intelligence technology, digital humans can provide people with more convenient, efficient, and personalized services. At the same time, the emergence of digital people can also promote the development of the virtual economy and provide more opportunities for digital content innovation and digital consumption.
According to a report released by International Data Corporation (IDC), the global virtual digital human market is expected to reach US$27 billion in 2025, with a compound annual growth rate of 22.5%. It can be seen that digital humans have very broad application prospects and market potential.
What is a digital person?
Digital people are digital characters created using digital technology that are close to human images. From a narrow perspective, digital human is the product of the integration of information science and life science. It uses information science methods to conduct virtual simulations of the human body's forms and functions at different levels. From a broad perspective, digital human refers to the penetration of digital technology at all levels and stages of human anatomy, physics, physiology and intelligence.
The core technologies of Digital Human include computer graphics, motion capture, image rendering, artificial intelligence, etc.
Among them, computer graphics can simulate human appearance, posture, expression, etc., so that digital people have realistic visual effects.
Motion capture technology converts the movements and expressions of real people into digital signals. These signals can drive the movements and expressions of digital human models to make them similar to or more expressive than real people.
Image rendering is to reproduce the visual effects of the real world in a digital environment, which requires precise calculations of light, color, material, etc. to create realistic images.
Artificial intelligence gives digital people a "soul" so that digital people can have the ability to interact intelligently. This is also a key technology that allows users to feel more personalized digital people.
What are the types of digital people?
With the continuous iteration of technology, the production efficiency and intelligence level of digital people are also constantly improving, and their application scope continues to expand. According to the classification of business scenarios, it is mainly divided into four types:
First, virtual agent
Virtual agents can provide automated and intelligent information consulting and services to enterprises and customers through technologies such as natural language processing and machine learning. Virtual agents are commonly used in various fields, such as customer service, education and training, financial consulting, etc.
Digital humans can serve as a form of virtual agent, especially in the field of customer service. Through digital technology, digital humans can provide 24-hour customer service and can understand and answer customer questions through natural language processing technology. In addition, digital humans can provide more personalized services by analyzing customer data and feedback.
Second, virtual assistant
Virtual assistant is an advanced form of chatbot that handles more complex interactions in a conversational manner. The key feature of the value-added service is the ability to recognize voice commands using advanced artificial intelligence, natural language processing and machine learning. VASs can leverage other platforms, for example, by accessing users' calendars and emails to schedule meetings, send emails, purchase concert tickets, or book hotels.
Also, the use of digital assistants has great potential in industries such as healthcare and retail. For medical professionals, digital assistants can help improve training and procedures. Doctors can perform surgeries in a realistic simulated environment, and they can perform hundreds of simulations to ensure the best results before performing surgery in real life. In retail, AI digital assistants can enhance customer service by providing a more personalized experience.
To do this, digital assistants need a good understanding of verbal communication. This is key to helping people better interact and converse with digital assistants so they can complete the tasks they need.
Third, virtual idols
Virtual idols are an application of digital people. They are usually active on social media networks and have influence and communication power on the public. A virtual idol can be a fictional virtual character or a digital representation of a real person. Compared with ordinary digital people, virtual idols pay more attention to image and performance, and usually require professional planning and production teams to create.
Fourth, virtual customer service
Virtual customer service is also a virtual character created through digital technology, but it is mainly used in the field of customer service. Virtual customer service is usually deployed on the company's official website, online customer service system, intelligent customer service and other platforms to interact with users in real time through text, voice, video, etc., to assist users in solving problems and obtaining information.
Fifth, virtual companionship
Virtual companionship provides emotional support and establishes a personal relationship with the user. Researchers believe the developing technology will have its biggest impact on elderly care by reducing loneliness and helping people stay at home longer. In addition to reminding people when they need to take their medication or see a doctor, a virtual companion will be able to carry on a conversation and show empathy.
However, it should be pointed out that the development of digital people also faces some difficulties. First of all, the creation of digital humans requires high costs and technical support, and only a few professional companies can invest a lot of money and technology in research and development. Secondly, there are still limitations and deficiencies in the behavior and performance of digital humans, such as the lack of real human emotions and consciousness, and the inability to fully simulate the behavior and language of real humans. In addition, the popularity and acceptance of digital people also need to be further improved. Although digital people have made certain progress, more technological advancements and application practices are still needed to make them more natural, real and useful.
Therefore, in order to make digital people more realistic, further technological innovation and research are needed to continuously improve their intelligence level and behavioral performance.
Written at the end:
In short, digital people, as an emerging field, are full of opportunities and challenges. But what is certain is that with the continuous innovation of technology, digital people will continue to mature and become an indispensable part of people's lives and work.

Context-augmented AI coding assistant using Rag and Sem-Rag
Jun 10, 2024 am 11:08 AM
Improve developer productivity, efficiency, and accuracy by incorporating retrieval-enhanced generation and semantic memory into AI coding assistants. Translated from EnhancingAICodingAssistantswithContextUsingRAGandSEM-RAG, author JanakiramMSV. While basic AI programming assistants are naturally helpful, they often fail to provide the most relevant and correct code suggestions because they rely on a general understanding of the software language and the most common patterns of writing software. The code generated by these coding assistants is suitable for solving the problems they are responsible for solving, but often does not conform to the coding standards, conventions and styles of the individual teams. This often results in suggestions that need to be modified or refined in order for the code to be accepted into the application
Can fine-tuning really allow LLM to learn new things: introducing new knowledge may make the model produce more hallucinations
Jun 11, 2024 pm 03:57 PM
Large Language Models (LLMs) are trained on huge text databases, where they acquire large amounts of real-world knowledge. This knowledge is embedded into their parameters and can then be used when needed. The knowledge of these models is "reified" at the end of training. At the end of pre-training, the model actually stops learning. Align or fine-tune the model to learn how to leverage this knowledge and respond more naturally to user questions. But sometimes model knowledge is not enough, and although the model can access external content through RAG, it is considered beneficial to adapt the model to new domains through fine-tuning. This fine-tuning is performed using input from human annotators or other LLM creations, where the model encounters additional real-world knowledge and integrates it

To provide a new scientific and complex question answering benchmark and evaluation system for large models, UNSW, Argonne, University of Chicago and other institutions jointly launched the SciQAG framework
Jul 25, 2024 am 06:42 AM
Editor |ScienceAI Question Answering (QA) data set plays a vital role in promoting natural language processing (NLP) research. High-quality QA data sets can not only be used to fine-tune models, but also effectively evaluate the capabilities of large language models (LLM), especially the ability to understand and reason about scientific knowledge. Although there are currently many scientific QA data sets covering medicine, chemistry, biology and other fields, these data sets still have some shortcomings. First, the data form is relatively simple, most of which are multiple-choice questions. They are easy to evaluate, but limit the model's answer selection range and cannot fully test the model's ability to answer scientific questions. In contrast, open-ended Q&A
