Large language models (LLMs) excel at general question-answering (Q&A) but often fall short in specialized domains due to a lack of domain-specific knowledge. Commercial companies face the dual challenges of privacy protection and resource constraints when involving LLMs for fine-tuning. This paper propose a novel framework, Self-Evolution, designed to address these issues by leveraging lightweight open-source LLMs through multiple iterative fine-tuning rounds. To enhance the efficiency of iterative fine-tuning, Self-Evolution employ a strategy that filters and reinforces the knowledge with higher value during the iterative process. We employed Self-Evolution on Qwen1.5-7B-Chat using 4,000 documents containing rich domain knowledge from China Mobile, achieving a performance score 174% higher on domain-specific question-answering evaluations than Qwen1.5-7B-Chat and even 22% higher than Qwen1.5-72B-Chat. Self-Evolution has been deployed in China Mobile's daily operation and maintenance for 117 days, and it improves the efficiency of locating alarms, fixing problems, and finding related reports, with an average efficiency improvement of over 18.6%. In addition, we release Self-Evolution framework code in https://github.com/Zero-Pointer/Self-Evolution.

Artificial intelligence has proven to be a technology that has the potential to change any industry. Chatbots are among the most popular marketing tools, and they represent only one of many areas of application of AI. Thanks to machine learning, AI can not only operate massive amounts of data but also learn from its previous experiences and improve its approaches. Given that 5G enables a much faster transfer of data, it allows developers to expand the functionality of mobile applications and to introduce new features. Let's consider the relationship between these two most promising technologies in more detail.

China Mobile is stepping up efforts to promote its 5G and artificial intelligence services by targeting "Generation Z" consumers. M-zone, a popular brand under China Mobile, has teamed up with pop idol Zhang Yixing to popularize new services, including co-branded Xback smartphone phone SIM cards, virtual photo-taking services supported by augmented reality and virtual reality technologies, as well as AI-enabled avatar services. Zhang has also become a partner with M-zone's 5G services and a promoter of its AI services. M-zone's Xback SIM cards are part of the company's broader efforts to better commercialize 5G technologies to create new value. Given Chinese pop idols' growing appeal to tech-savvy, young subscribers, China Mobile hopes pop idols can help boost the popularity of its 5G services.

When China's wireless carriers debut their 5G networks this year, early adopters whose mobile phones can handle the ultra-fast speeds won't be the only beneficiaries. Rolling 5G service out to the world's biggest population also should give a boost to China's digital economy, including makers of telecommunications equipment, platforms and applications for the internet of things, autonomous driving, surveillance and factory automation. It's the kind of head start that will be expensive at first but could pay off well into the future. Major cities including Beijing, Shanghai and Shenzhen will get broad 5G -- or fifth-generation -- wireless coverage first, while some other cities will start with 5G hotspots.

China is moving forward in the global "race to 5G," as state-owned carrier China Mobile has announced (via Xinhua) that it's already building the first 5G smart highway -- a city-scale system of roads capable of supporting cellular network-coordinated transportation services. The infrastructure is currently under construction in Wuhan, the capital of China's centrally located Hubei Province. As the country's largest telecommunications company, China Mobile plans to roll out a collection of 5G services on the highway, beginning with "smart toll stations" that could do away with current toll transponders and human operators. The carrier also plans to gather real-time traffic information and make AI-assisted predictions using the data, as well as supporting autonomous cars. While China Mobile isn't the world's first carrier to either announce 5G highway plans or begin limited deployments, it may wind up being the first to offer actual commercial and coordinated transportation services on live highways -- depending on progress made by rivals in other countries.

Nokia and China Mobile, the world's largest mobile carrier in terms of subscribers, have signed an Memorandum of Understanding (MoU) to investigate the potential of artificial intelligence (AI) and machine learning to optimize future networks and enable the delivery of new edge cloud and 5G services. Under the terms of the agreement, the two companies will jointly establish a laboratory in Hangzhou, China to develop the demo system to verify technology use cases using Nokia's 5G Future X architecture. The deal also stipulates that China Mobile will lead the research in terms of scenario selection, requirements confirmation, open API standardization and solution definition. Under the MoU, Nokia and China Mobile will work together to research the application of AI and machine learning to ensure any changes in demand are predicted and network resources are automatically allocated to meet all service demands with consistent high quality and reliability, the two firms said. At the new laboratory in Hangzhou, Nokia and China Mobile will foster an open Radio Access Network and 5G ecosystem working with third parties to leverage AI and machine learning and optimize networks for the delivery of services such as cloud virtual reality gaming.

I visited Beijing last week and learned a great deal from Microsoft's AI //innovate event in China - our 2nd largest developer base for Cognitive Services on Azure. The most heart-felt demo was Harry Shum could communicate with an almost deaf student of Nanjing University of Technology. Using two mobile phones with Microsoft Translator, the deaf student not only had no problem to communicate with Harry but also removed his language barriers between Chinese and English! I started speech recognition research as a graduate student in Beijing's Tsinghua University more than 35 years ago. My graduate student dream was to help people communicate better without language barriers.

CloudMinds, a cloud robotics start-up founded by the former head of the research division of China Mobile, has raised US 30 million seed financing from SB China Capital (SBCVC), Hon Hai Precision Industry Co., Ltd., Walden International and Kaixuan Capital. Cloud robotics is an emerging field of robotics rooted in cloud computing and cloud storage centered around the benefits of converged infrastructure and shared services. Huang Xiaoqing left the Research Institution of China Mobile last March to launch CloudMinds, according to an article published by Caixin Media. "A robot with similar capabilities of a real human requires a computer system that may be one million times bigger in size than that of a human brain, which means the brain of a robot must be on the cloud," Huang told the Chinese media organization. CloudMinds is targeting to reveal a full-service housekeeping robot in 2025 to service individual families.
