1,C + + 20 standard officially released

In 2020h1, the scale growth of China's AI cloud service market far exceeded expectations; C + + 20 standard officially released

Recently, the ISO C + + Committee officially released the C + + 20 standard, named ISO / IEC 14882:2020. This major update introduces many new features:

  • Modules
  • Coroutines
  • Ranges
  • Constraints and concepts
  • Designated initializers
  • Operator < = >! = = = Constexpr supports: new / delete, dynamic_ Cast, try / catch, virtual
  • Constexpr vectors and strings
  • Timing: calendar and time zone support
  • std::format 
  • std::span 
  • std::jthread

Concepts / ranges / modules / coroutines these new features will not only have a great impact on developers and C + + ecology, but also add a lot of charm to this “old age” programming language.

In 2020h1, the scale growth of China's AI cloud service market far exceeded expectations; C + + 20 standard officially released

According to the latest report on tracking China’s AI cloud service market (the first half of 2020) released by IDC,In the first half of 2020, the scale of China’s AI cloud service market reached 1.09 billion yuan, an increase of more than 100% compared with the first half of 2019。 Cloud service providers can provide rich and fast iterative single point AI capabilities, and also have the ability to create application scenario solutions and overall industry solutions for industry users. The AI public cloud service market is still in its early stage. In the future, AI cloud service manufacturers will gain a higher and higher market share in the overall AI software and application market.

3,Nature: beyond region and culture, AI recognizes 16 common facial expressions of all mankind

In 2020h1, the scale growth of China's AI cloud service market far exceeded expectations; C + + 20 standard officially released

Researchers from the University of California, Berkeley and Google used machine learning and YouTube videos to compare common facial expressions with situations that trigger expressions. It was found that whether at a birthday party in Brazil, a funeral in Kenya, or a square dance in a Chinese park,Human beings in similar social environment will use the same facial expressions, such as smile, frown and bitter face. in other words, the rich facial expressions of human beings can transcend regions and cultures. The study, published in the December 16 issue of nature, confirms the universality of human emotional expression across regional and cultural boundaries.

4,Muzero, deepmind’s latest AI product, can master the game without knowing the rules

In 2020h1, the scale growth of China's AI cloud service market far exceeded expectations; C + + 20 standard officially released

According to foreign media reports, muzero, the latest artificial intelligence product of deep mind, a subsidiary of alphabet focusing on artificial intelligence, can master the game without knowing the rules. Deepmind’s mission is to show people that AI can not only really master games, but also do so without being told the rules of the game. On Wednesday local time, the company introduced muzero in detail. Muzero is aYou can master the artificial intelligence of the game without learning the rules of the game in advance。 Muzero can achieve this goal not only through visual simple games with complex strategies (such as go, chess and Japanese general chess), but also through visually complex yadali games. Instead of using rules to find the best situation, it learns to consider all aspects of the game environment and observe whether it is important.

5,The highest availability is guaranteed to reach 99.995% of JD Zhilian cloud upgrade SLA service standard

In 2020h1, the scale growth of China's AI cloud service market far exceeded expectations; C + + 20 standard officially released

Recently, JD Zhilian cloud released a newly upgraded cloud computing service level agreement,The maximum availability guarantee is 99.995%。 This means that JD Zhilian cloud, as a cloud computing service provider, has ranked among the world’s top cloud computing manufacturers in terms of service availability. Behind the value of “99.995%” is the high-level cutting-edge technical capability advantage and rich business experience of JD Zhilian cloud. The technical capability of JD Zhilian cloud has been tempered by JD retail, JD logistics, JD digital and other core businesses within JD group, and has passed the tests of JD 618 and JD 11.11 over the years. It has long-term technical accumulation and practice in ensuring service availability.

6,Mimik works with IBM to make edge computing resources more accessible

In 2020h1, the scale growth of China's AI cloud service market far exceeded expectations; C + + 20 standard officially released

Mimik, an edge computing startup, is working with IBM to create edge based computing resources, which are said to help accelerate the automation and digital transformation of healthcare, manufacturing, retail and other industries. Mimik said on December 24 that the growth of trends such as “Internet of things” and 5g has led to the emergence of billions of interconnected devices and applications at the edge of the network. However, these devices and applications rely on computing resources located in the centralized data center. They are becoming a burden of bandwidth and therefore difficult to manage.

Mimik’s cooperation with IBM can help solve this problem. The company created a hybrid edgecloud platform,The platform can work by converting devices such as smartphones and PCs into “cloud servers” that can run at the edge of the network。 The edgecloud platform can leverage these devices to enable them to communicate with each other in small local clusters, regardless of the operating system and network on which they are running. This makes it possible to use their combined computing resources to power applications at the network edge.

1,Doctoral Dissertation of Fudan University, “microservice fault location based on trajectory analysis”

In 2020h1, the scale growth of China's AI cloud service market far exceeded expectations; C + + 20 standard officially released

As a new form of cloud based software system, microservice system still lacks corresponding summary of its software fault characteristics, At the same time, there is also a lack of open microservice systems (such as open source projects) for research. Therefore, this paper, trace analysis based fault localization for microservice systems, conducted an industrial investigation on the development practice of microservice systems, systematically understood the characteristics of industrial microservice systems, and collected a set of dataTypical microservice fault cases and corresponding fault analysis and debugging practice methods, and analyzes the practical problems and challenges. On this basis, they developed a medium-sized microservice benchmark system, reproduced 22 industrial failure cases, and released it through the open source community. Based on this open source microservice benchmark system and corresponding fault cases, a series of microservice fault auxiliary location methods and technologies are studied.

2,AAAI 2021 | sentence semantic relation matching from the perspective of semantic relation modeling

In 2020h1, the scale growth of China's AI cloud service market far exceeded expectations; C + + 20 standard officially released

Sentence semantic relation matching is a basic but important task in natural language processing, and has a wide range of application scenarios, such as retrieval, dialogue, question and answer and so on. The existing methods can be roughly divided into two categories: one is to directly model the sentence itself, use Bert, LSTM and other methods, or generate semantic representation vectors for matching analysis, or directly analyze the matching between words and phrases from a fine-grained point of view; The other class also considers the tag information, because the tag also contains some semantic information. The rich information is supplemented by the method of label embedding, so as to obtain the relationship of sentence semantic matching.

This paper holds that the semantics of the tag more points out the semantic relationship between the two sentences, which is ignored by the existing research. Through the mining of semantic relationship, we can more deeply mine the semantic information of the sentence, extract the features related to the semantic relationship, and achieve better sentence semantic relationship modeling. To this end,In this paper, relation of relation modeling is proposed to analyze sentence semantic relation matching modeling from the perspective of semantic relation modeling
