How to configure workgroup in win11 system Feb 22, 2024 pm 09:50 PM

How to configure a workgroup in Win11 A workgroup is a way to connect multiple computers in a local area network, which allows files, printers, and other resources to be shared between computers. In Win11 system, configuring a workgroup is very simple, just follow the steps below. Step 1: Open the "Settings" application. First, click the "Start" button of the Win11 system, and then select the "Settings" application in the pop-up menu. You can also use the shortcut "Win+I" to open "Settings". Step 2: Select "System" In the Settings app, you will see multiple options. Please click the "System" option to enter the system settings page. Step 3: Select "About" In the "System" settings page, you will see multiple sub-options. Please click

MIT's latest masterpiece: using GPT-3.5 to solve the problem of time series anomaly detection Jun 08, 2024 pm 06:09 PM

Today I would like to introduce to you an article published by MIT last week, using GPT-3.5-turbo to solve the problem of time series anomaly detection, and initially verifying the effectiveness of LLM in time series anomaly detection. There is no finetune in the whole process, and GPT-3.5-turbo is used directly for anomaly detection. The core of this article is how to convert time series into input that can be recognized by GPT-3.5-turbo, and how to design prompts or pipelines to let LLM solve the anomaly detection task. Let me introduce this work to you in detail. Image paper title: Largelanguagemodelscanbezero-shotanomalydete

Improved detection algorithm: for target detection in high-resolution optical remote sensing images Jun 06, 2024 pm 12:33 PM

01 Outlook Summary Currently, it is difficult to achieve an appropriate balance between detection efficiency and detection results. We have developed an enhanced YOLOv5 algorithm for target detection in high-resolution optical remote sensing images, using multi-layer feature pyramids, multi-detection head strategies and hybrid attention modules to improve the effect of the target detection network in optical remote sensing images. According to the SIMD data set, the mAP of the new algorithm is 2.2% better than YOLOv5 and 8.48% better than YOLOX, achieving a better balance between detection results and speed. 02 Background & Motivation With the rapid development of remote sensing technology, high-resolution optical remote sensing images have been used to describe many objects on the earth’s surface, including aircraft, cars, buildings, etc. Object detection in the interpretation of remote sensing images
