- ICLR 2024 | Model critical layers for federated learning backdoor attacks
- Federated learning uses multiple parties to train models while data privacy is protected. However, because the server cannot monitor the training process performed locally by participants, participants can tamper with the local training model, thus posing security risks to the overall federated learning model, such as backdoor attacks. This article focuses on how to launch a backdoor attack on federated learning under a defensively protected training framework. This paper finds that the implantation of backdoor attacks is more closely related to some neural network layers, and calls these layers the key layers for backdoor attacks. In federated learning, clients participating in training are distributed on different devices. They each train their own models, and then upload the updated model parameters to the server for aggregation. Since the client participating in the training is not trustworthy, there are certain risks, so

- US$100,000 to train Llama-2 large model! All Chinese people build a new MoE, Jia Yangqing, former CEO of SD, looks on
- To learn more about AIGC, please visit: 51CTOAI.x community https://www.51cto.com/aigc/ "Only" US$100,000 is needed to train a large model at the Llama-2 level. A MoE model with smaller size but no loss in performance is here: it is called JetMoE and comes from research institutions such as MIT and Princeton. The performance is significantly higher than that of Llama-2 of the same size. △Reposted by Jia Yangqing You must know that the latter has an investment cost of billions of dollars. JetMoE is completely open source when released and is friendly to academia: it only uses public data sets and open source code, and can be fine-tuned with consumer-grade GPUs. Needless to say, the cost of building large models is really much cheaper than people think. Ps.S

- A Diffusion Model Tutorial Worth Your Time, from Purdue University
- Diffusion can not only imitate better, but also "create". The diffusion model (DiffusionModel) is an image generation model. Compared with the well-known algorithms such as GAN and VAE in the field of AI, the diffusion model takes a different approach. Its main idea is a process of first adding noise to the image and then gradually denoising it. How to denoise and restore the original image is the core part of the algorithm. The final algorithm is able to generate an image from a random noisy image. In recent years, the phenomenal growth of generative AI has enabled many exciting applications in text-to-image generation, video generation, and more. The basic principle behind these generative tools is the concept of diffusion, a special sampling mechanism that overcomes the limitations of previous methods.

- What is generative AI? What feature types are there
- Generative AI is a type of human artificial intelligence technology that can generate various types of content, including text, images, audio and synthetic data. So what is artificial intelligence? What is the difference between artificial intelligence and machine learning? What are the technical features? Artificial intelligence is the discipline, a branch of computer science, that studies the creation of intelligent agents. These are systems in which intelligent agents can reason, learn, and act autonomously. The study of intelligent agents is the study of systems that can reason, learn, and act autonomously. Artificial intelligence is concerned with the theories and methods of building machines that think and act like humans. Within this discipline, machine learning is a field of artificial intelligence. It is a program or system that trains a model based on input data. The trained model can be trained from new or unseen data.

- Will AI threaten 8 million British jobs? IPPR: Can't just benefit tech giants
- The British Institute for Public Policy Research (IPPR) recently pointed out in a report that 8 million jobs in the UK will be threatened due to the popularity of AI. However, reports show that, albeit at its worst, AI can stimulate economic growth and make existing jobs more powerful through government intervention and concentrated regulation. This concept will be very critical in the next few years. If the government can formulate reasonable policies, AI will bring about GPD growth. If it is not reasonable, a large number of jobs will disappear. The AI impact is divided into two stages. IPPR believes that generating an AI will be divided into two stages when it becomes popular. The first phase is what is happening now, marked by the rise of generative AI platforms, such as GPT-4. In the second stage, companies will integrate generative AI technology

- The first domestic AI programmer joins Alibaba Cloud: exclusive job number AI001, KPI is that one person can write 20% of the company's code
- You must have heard a saying: You should start learning computers from childhood. In the past many years, learning to program has been a fashionable thing, but with the development of generative AI technology, the attitude of the technology circle seems to have changed. Nvidia CEO Jensen Huang said: "In the future, just leave programming to AI. From now on, everyone will be a software engineer." Soon after, Devin, the world's first AI software engineer, shocked developers and really aroused people's interest in There is a heated discussion about the future prospects of the career of programmers. Is it possible that the jobs of programmers are really going to be taken away by AI? In fact, this is not the case. AI is still just a work assistant for programmers. In fact, there is an AI programmer in China who has been working at a major Internet company for some time. It is the tens of thousands of workers at Alibaba Cloud

To learn more about AIGC, please visit: 51CTOAI.x community https://www.51cto.com/aigc/ Last year, the emergence of AutoGPT made us realize the powerful automation capabilities of AI agents and created a new AI Agency track. However, there are still many problems that need to be solved in sub-task scheduling, resource allocation and collaboration between AI. So researchers at Rutgers University developed AIOS, an AI agent operating system with large models at its core. It can effectively solve the problem of low resource call rate as the number of AI agents increases. It can also promote context switching between agents and realize concurrent agent merging.

- To learn more about AIGC, please visit: 51CTOAI.x community https://www.51cto.com/aigc/ Recently, many people are worried about AI replacing their jobs. Devin, the "first AI programmer" who became popular in the AI circle last month, has mastered full-stack skills by using large model capabilities. He can automatically complete complex code tasks by only requiring humans to give natural language instructions. The tool capabilities demonstrated by Devin are very amazing, especially for this startup that takes the closed source route. Currently, only a few people can use this closed beta quota. On Tuesday, researchers from Princeton University’s NLP group released SWE-agent, an open source version of the AI program.

- Is artificial intelligence overrated?
- There is no doubt that artificial intelligence has become one of the hottest topics in recent years, capturing the imagination of technology experts, entrepreneurs and the public. However, amid the hype and excitement surrounding artificial intelligence, there is a growing debate about whether artificial intelligence is overvalued. Some commentators believe that AI is simply an advanced form of curve fitting rather than the revolutionary technology it is portrayed to be. Nonetheless, the development and application of artificial intelligence is still very impressive. From self-driving vehicles to smart homes, artificial intelligence has penetrated into every aspect of our lives. Its potential is limitless. However, we cannot ignore the challenges and problems faced by artificial intelligence. A key question is the growing debate over whether artificial intelligence is overrated. The core of artificial intelligence is to develop algorithms and systems
