4. Issued by the ministry of industry and information technology 《“ Double Gigabit ” Network collaborative development action plan (2021-2023 year )》

3 month 24 Japan , Issued by the ministry of industry and information technology 《“ Double Gigabit ” Network collaborative development action plan (2021-2023 year )》, As a whole to promote “ Double Gigabit ” Network development .《 plan 》 Put forward “ Optimize data center connectivity (DCI) Ability ”、“ Continuously optimize the network architecture ” Wait for action , take “ At least 2 A national Internet backbone direct connection point ”. According to the report : With gigabit optical network and 5G As a representative of the “ Double Gigabit ” The Internet , It can provide Gigabit access to fixed and mobile networks for a single user , It has huge bandwidth 、 Ultra low delay 、 Advanced and reliable , The two complement each other , It's an important part of the new infrastructure and a bearing base . For implementation 《 Government work report 》 Deployment requirements , advance “ Double Gigabit ” Network construction promotes each other 、 Application advantages complement each other 、 Innovation, business integration , Further develop “ Double Gigabit ” The Internet is driving effective investment 、 It plays an important role in promoting information consumption and assisting the digital transformation of manufacturing industry , Accelerate the construction of a new development pattern , Develop this action plan .

5. Microsoft Edge PWA The app will be visually consistent with the native app

Microsoft Edge The browser will introduce an item called “Window Controls Overlay” New functions , Enables developers to customize their PWA The title bar area of , In order to make PWA Applications are visually consistent with native applications . In recent days, , A technical document revealed that Microsoft Edge Browser's next move —— Cancel Edge The title bar , Give Way Web Developers are free to control this area . Microsoft Edge Team Amanda Baker Express... In technical documents :" This feature enables developers to build Web application , And allow them to Web Applications are designed more like native applications . As the device becomes smaller , More and more portability , The title bar takes up a very large part of the screen space , Leave it to users and Web The space for application interaction is correspondingly smaller ."

6. China's cloud infrastructure spending hit a new high , The growth rate is the highest in the world

Market research institute Canalys Released 《China cloud services market Q4 2020》 According to the report , 2020 Fourth quarter of 2007 , China's spending on cloud infrastructure services has increased 62%, achieve 58 Billion dollars , Set a new record . The high increase indicates that China's demand for cloud services is strong . And the digital transformation efforts during the pandemic , And China's rapid economic recovery and the subsequent restart of delayed projects , Is the main factor driving this growth .Canalys Research Analyst Blake Murray call , Customers ask cloud service providers to provide more advanced solutions , To meet data security requirements and other specific industry needs .

This is accelerating data center capacity 、 The development of connectivity and data services .

Academic frontier

1. Beyond convolution 、 Self attention mechanism : New powerful neural networks involution

Ordinary convolution Of kernel It has two basic characteristics: space invariance and channel specificity ; and involution On the contrary , It has channel invariance and spatial specificity . In this paper, a new neural network operator called involution, It is better than convolution Lighter, more efficient , In form self-attention More concise , It can be used to improve the accuracy and efficiency of various visual task models . adopt involution Structural design of , We can understand the classical convolution operation and the recently popular self attention operation from a unified perspective .

2.WWW 2021 | Control the risk of dialogic retrieval through reinforcement learning

In this paper , The author lists the risks of asking users clarification questions in a conversation search . In this paper, we propose a dialogue agent considering risk , Through comprehensive evaluation and comparison, the agent makes decisions between asking clarifying questions and answering users' queries . During the training , The author puts forward to strengthen learning to train , There is no need to put forward the annotated data to clarify the question and provide the user with the answer . Through simulation experiments using different user models , The author proves that the agent can improve the quality of answer and user experience when interacting with the retrieval system .
