AI subtitles use Xiaomi’s self-developed simultaneous interpretation technology to provide a faster, more stable and accurate subtitle reading experience. 1. According to the official statement, Xiaoai Translator can not only be used in audio and video venues
This article is enough for you to read about autonomous driving and trajectory prediction!
Feb 28, 2024 pm 07:20 PM
Trajectory prediction plays an important role in autonomous driving. Autonomous driving trajectory prediction refers to predicting the future driving trajectory of the vehicle by analyzing various data during the vehicle's driving process. As the core module of autonomous driving, the quality of trajectory prediction is crucial to downstream planning control. The trajectory prediction task has a rich technology stack and requires familiarity with autonomous driving dynamic/static perception, high-precision maps, lane lines, neural network architecture (CNN&GNN&Transformer) skills, etc. It is very difficult to get started! Many fans hope to get started with trajectory prediction as soon as possible and avoid pitfalls. Today I will take stock of some common problems and introductory learning methods for trajectory prediction! Introductory related knowledge 1. Are the preview papers in order? A: Look at the survey first, p
The Stable Diffusion 3 paper is finally released, and the architectural details are revealed. Will it help to reproduce Sora?
Mar 06, 2024 pm 05:34 PM
StableDiffusion3’s paper is finally here! This model was released two weeks ago and uses the same DiT (DiffusionTransformer) architecture as Sora. It caused quite a stir once it was released. Compared with the previous version, the quality of the images generated by StableDiffusion3 has been significantly improved. It now supports multi-theme prompts, and the text writing effect has also been improved, and garbled characters no longer appear. StabilityAI pointed out that StableDiffusion3 is a series of models with parameter sizes ranging from 800M to 8B. This parameter range means that the model can be run directly on many portable devices, significantly reducing the use of AI
Golang's life or death is uncertain? Google's attitude revealed
Mar 06, 2024 pm 05:42 PM
The Internet industry is developing at a rapid pace, and programming languages are also constantly evolving. Among many programming languages, Golang (Go), as a relatively young language, has attracted much attention since its inception. However, there have been various opinions and speculations about Golang's prospects and development trends. Is Golang’s life or death still uncertain? What is Google's attitude towards Golang? Golang, as an open source programming language developed by Google, has attracted much attention since its birth. It is designed to
How to solve the problem that Google Chrome's built-in translation fails?
Mar 13, 2024 pm 08:46 PM
Browsers generally have built-in translation functions, so you don’t have to worry about not being able to understand when browsing foreign language websites! Google Chrome is no exception, but some users find that when they open the translation function of Google Chrome, there is no response or failure. What should they do? You can try the latest solution I found. Operation tutorial: Click the three dots in the upper right corner and click Settings. Click Add Language, add English and Chinese, and make the following settings for them. The English setting asks whether to translate web pages in this language. The Chinese setting displays web pages in this language, and Chinese must be moved to the top before it can be set as the default language. If you open the webpage and no translation option pops up, right-click and select Translate Chinese, OK.
DualBEV: significantly surpassing BEVFormer and BEVDet4D, open the book!
Mar 21, 2024 pm 05:21 PM
This paper explores the problem of accurately detecting objects from different viewing angles (such as perspective and bird's-eye view) in autonomous driving, especially how to effectively transform features from perspective (PV) to bird's-eye view (BEV) space. Transformation is implemented via the Visual Transformation (VT) module. Existing methods are broadly divided into two strategies: 2D to 3D and 3D to 2D conversion. 2D-to-3D methods improve dense 2D features by predicting depth probabilities, but the inherent uncertainty of depth predictions, especially in distant regions, may introduce inaccuracies. While 3D to 2D methods usually use 3D queries to sample 2D features and learn the attention weights of the correspondence between 3D and 2D features through a Transformer, which increases the computational and deployment time.
What is the correct way to restart a service in Linux?

What is the correct way to restart a service in Linux? When using a Linux system, we often encounter situations where we need to restart a certain service, but sometimes we may encounter some problems when restarting the service, such as the service not actually stopping or starting. Therefore, it is very important to master the correct way to restart services. In Linux, you can usually use the systemctl command to manage system services. The systemctl command is part of the systemd system manager
