Kimi: In just one sentence, in just ten seconds, a PPT will be ready. PPT is so annoying! To hold a meeting, you need to have a PPT; to write a weekly report, you need to have a PPT; to make an investment, you need to show a PPT; even when you accuse someone of cheating, you have to send a PPT. College is more like studying a PPT major. You watch PPT in class and do PPT after class. Perhaps, when Dennis Austin invented PPT 37 years ago, he did not expect that one day PPT would become so widespread. Talking about our hard experience of making PPT brings tears to our eyes. "It took three months to make a PPT of more than 20 pages, and I revised it dozens of times. I felt like vomiting when I saw the PPT." "At my peak, I did five PPTs a day, and even my breathing was PPT." If you have an impromptu meeting, you should do it

In the early morning of June 20th, Beijing time, CVPR2024, the top international computer vision conference held in Seattle, officially announced the best paper and other awards. This year, a total of 10 papers won awards, including 2 best papers and 2 best student papers. In addition, there were 2 best paper nominations and 4 best student paper nominations. The top conference in the field of computer vision (CV) is CVPR, which attracts a large number of research institutions and universities every year. According to statistics, a total of 11,532 papers were submitted this year, and 2,719 were accepted, with an acceptance rate of 23.6%. According to Georgia Institute of Technology’s statistical analysis of CVPR2024 data, from the perspective of research topics, the largest number of papers is image and video synthesis and generation (Imageandvideosyn

We know that LLM is trained on large-scale computer clusters using massive data. This site has introduced many methods and technologies used to assist and improve the LLM training process. Today, what we want to share is an article that goes deep into the underlying technology and introduces how to turn a bunch of "bare metals" without even an operating system into a computer cluster for training LLM. This article comes from Imbue, an AI startup that strives to achieve general intelligence by understanding how machines think. Of course, turning a bunch of "bare metal" without an operating system into a computer cluster for training LLM is not an easy process, full of exploration and trial and error, but Imbue finally successfully trained an LLM with 70 billion parameters. and in the process accumulate

Editor of the Machine Power Report: Yang Wen The wave of artificial intelligence represented by large models and AIGC has been quietly changing the way we live and work, but most people still don’t know how to use it. Therefore, we have launched the "AI in Use" column to introduce in detail how to use AI through intuitive, interesting and concise artificial intelligence use cases and stimulate everyone's thinking. We also welcome readers to submit innovative, hands-on use cases.

An illustration-style animation, coupled with a few healing words, can be easily picked up in just a few days.

Retrieval-augmented generation (RAG) is a technique that uses retrieval to boost language models. Specifically, before a language model generates an answer, it retrieves relevant information from an extensive document database and then uses this information to guide the generation process. This technology can greatly improve the accuracy and relevance of content, effectively alleviate the problem of hallucinations, increase the speed of knowledge update, and enhance the traceability of content generation. RAG is undoubtedly one of the most exciting areas of artificial intelligence research. For more details about RAG, please refer to the column article on this site "What are the new developments in RAG, which specializes in making up for the shortcomings of large models?" This review explains it clearly." But RAG is not perfect, and users often encounter some "pain points" when using it. Recently, NVIDIA’s advanced generative AI solution

After rain in summer, you can often see a beautiful and magical special weather scene - rainbow. This is also a rare scene that can be encountered in photography, and it is very photogenic. There are several conditions for a rainbow to appear: first, there are enough water droplets in the air, and second, the sun shines at a low angle. Therefore, it is easiest to see a rainbow in the afternoon after the rain has cleared up. However, the formation of a rainbow is greatly affected by weather, light and other conditions, so it generally only lasts for a short period of time, and the best viewing and shooting time is even shorter. So when you encounter a rainbow, how can you properly record it and photograph it with quality? 1. Look for rainbows. In addition to the conditions mentioned above, rainbows usually appear in the direction of sunlight, that is, if the sun shines from west to east, rainbows are more likely to appear in the east.

One of the major changes introduced in MySQL 8.4 (the latest LTS release as of 2024) is that the "MySQL Native Password" plugin is no longer enabled by default. Further, MySQL 9.0 removes this plugin completely. This change affects PHP and other app

On July 24, Kuaishou video generation large model Keling AI announced that the basic model has been upgraded again and is fully open for internal testing. Kuaishou said that in order to allow more users to use Keling AI and better meet the different levels of usage needs of creators, from now on, on the basis of fully open internal testing, it will also officially launch a membership system for different categories of members. Provide corresponding exclusive functional services. At the same time, the basic model of Keling AI has also been upgraded again to further enhance the user experience. The basic model effect has been upgraded to further improve the user experience. Since its release more than a month ago, Keling AI has been upgraded and iterated many times. With the launch of this membership system, the basic model effect of Keling AI has once again undergone transformation. The first is that the picture quality has been significantly improved.
