Google released Flutter 2

On March 4th, Google announced the next generation of Flutter, Flutter 2, built for the Web, mobile, and desktop. To fundamentally change the way developers think about building applications, Flutter 2 expands Flutter from a mobile development framework to a portable one, so developers can extend their applications to the desktop or web without having to rewrite their code. Additionally, Flutter 2 can be used to achieve many functions:

  • Developers can use the same code base to distribute native apps to five operating systems: iOS, Android, Windows, macOS, and Linux.
  • Different web experiences for Chrome, Firefox, Safari or Edge;
  • The Flutter can also be embedded in cars, televisions and smart home appliances.

2. Jingdong Cloud’s new-generation self-research cloud server will be launched in April

March 2 news, a new generation of self-developed JINGdong cloud server will be launched in April 2021, the cloud instance carrying capacity will be more than 2 times higher than the standard product with the same price. The second generation of JINGdong cloud server will also shoulder the internal application support of JINGdong Group, as well as the external service of Jingdong Cloud. The second generation of jingdong cloud server is after the first generation of “customization” server, based on the internal diversification mass business requirements, and jingdong cloud industry needs of customers, independent research and development and the depth of the innovation of a new generation of cloud server infrastructure, through the system architecture design innovation, the core components, to achieve the goal of high efficiency, flexible and cost-effective. Later, JINGdong Cloud will also put these self-research innovation results, through the open source community to the industry, to make more contributions to the innovation and development of the IT industry.

3.Apache Flink 1.12.2 release, stream batch truly unified operation!

Apache Flink has arrived in version 1.12.2, which focuses on bug fixes. Here are some of the updates:

  • Fixed an issue where managed runs might not be released in a timely manner when operators frequently use managed memory;
  • Fix spelling errors in EXPLAIN statement documents
  • Record binary compatibility with Scala after 2.12.8, etc.

Sidewalk robots are already considered “pedestrians” in states like Pennsylvania

A sidewalk robot walks the sidewalk at the University of Texas at Dallas. “We already have about 1,000 of them running around,” Starship’s Ryan Tuohy said. As small robots proliferate on sidewalks and city streets, legislation also gives them generous access and, in the case of Pennsylvania, even classifies them as “pedestrians.”

5. Mixed reality platform Mesh was launched, integrating science fiction into reality

Microsoft has released the first promo for its mixed reality cloud platform Microsoft Mesh, demonstrating the presence and remote real-time sharing experience that MR (Mixed reality) products provide. Through the mixed reality technology, Mesh can realize the immersive sense of presence and shared experience on any device (mobile phone, tablet, PC, VR glasses, etc.). Let people separated by thousands of miles transmit their own images to the same space, virtual 3D content interaction, mutual communication. Microsoft launched two applications built on the Mesh platform: a Mesh preview version of user HoloLens for remote collaboration, access to the new mesh-enabled AltspaceVR, and enterprise-class security for meetings and work gatherings in virtual reality; Mesh is integrated into Teams and Dynamics 365, and we believe there will be more innovative application scenarios in the future.

6.Facebook’s new AI model, SEER, implements self-supervised learning

Facebook researchers have unveiled a new artificial intelligence model, SEER, that can learn from any random, untagged set of images on the Internet. The Facebook “breakthrough” is still in its early stages, but the team expects it to lead to a “revolution” in computer vision. SEER is self-supervised, trained by a billion publicly SupERvised Instagram images that have not been artificially engineered. That is, the images have not been labeled and annotated, which is usually used for algorithm training, but SEER can still independently use the data set to process data while learning, and finally achieve the highest accuracy in tasks such as object detection.

1.EMNLP 2020 | Text Enhanced Knowledge Graph Open domain Q&A based on Hyperedge Fusion

The incompleteness of knowledge base is the key factor limiting the performance of knowledge base question answering system. Outside the knowledge base, the text has more information than the knowledge base, which can be used to make up the incompleteness of the knowledge base, but at the same time, the text is more difficult for the computer to understand. This paper proposes a new QA method to enhance knowledge base by using text. The model enrichis entity representation by semantic information contained in text, and uses graph convolution network to update entity state. In addition, in order to explore the underlying structural information of texts, the author regards texts as hyperedges connecting entities to complement incomplete relationships in the knowledge base. Hypergraph convolutional networks are used for textual inference in hypergraph form. Experiments on WebQuestionSP benchmark test demonstrate the validity of this model in different KB.

COLING 2020 | Bidirectional cognitive thinking Network for Machine reading Comprehension

In this paper, the effect of machine reading comprehension model is improved by designing neural network to simulate reverse thinking and inertial thinking. The author uses human cognitive behavior habits for machine reading comprehension. Therefore, the problem that this paper needs to solve is: which behaviors and habits to use for reference, how to use for reference, and how to integrate with machine reading understanding model. In this paper, the effect of machine reading comprehension model is improved by designing neural network to simulate reverse thinking and inertial thinking.
