Industry news News
1. Google releases Flutter 2
On March 4, Google launched the next generation of flutter, built specifically for the web, mobile and desktop Flutter 2！In order to fundamentally change the developers’ view on building applications, flutter 2, a major upgrade of flutter, willFlutter extends from mobile development framework to portable framework, so developers can extend their applications to desktop or web pages without rewriting the code.In addition, many functions can be realized with flutter 2
- Developers can use the same code base to publish local applications to five operating systems: IOS, Android, windows, Mac OS and Linux;
- Provide different Web experiences for chrome, Firefox, safari or edge;
- Flutter can also be embedded in cars, TVs and smart home appliances.
2. The new generation of self-developed cloud server of JD cloud was launched in April
According to the news on March 2, a new generation of self-developed JD cloud server will be launched in April 2021,The carrying capacity of cloud instances will be more than 2 times higher than that of standard products with the same price.The second generation of JD cloud server will be responsible for both the internal application support of JD group and the external service of JD cloud. Following the “micro customization” of the first generation server, the second generation of JD cloud server is based on the internal diversified massive business needs and the customer needs of various industries of JD cloud,A new generation of cloud server infrastructure with independent R & D and deep innovation,Through the innovation of system architecture design and core components, the goal of high efficiency, flexibility and cost performance is achieved. In the future, JD cloud will give back these self-developed innovative achievements to the industry through open source community, so as to make more contributions to the innovation and development of IT industry.
3. Apache Flink 1.12.2 release, stream batch integration, truly unified operation!
Apache Flink comes to version 1.12.2, which focuses on bug fixing. Here are some updates:
- Fix the problem that the run in the managed memory may not be released in time when the operator uses the managed memory frequently;
- Fix the spelling errors in the explain statement document;
- Record the binary compatibility with Scala after 2.12.8.

4. Sidewalk robots have been regarded as “pedestrians” in Pennsylvania and other states
At the University of Texas in Dallas, a walking robot walks on the sidewalk“We already have about 1000 of these robots running around“Says Ryan Tuohy of starship. With the proliferation of small robots on sidewalks and city streets, legislation has given them generous access, even classifying them as “pedestrians” in the case of Pennsylvania.
5.Hybrid reality platform mesh launched, science fiction into reality
On March 6, Microsoft recently released the first promotional video of the hybrid reality cloud platform “Microsoft mesh”, which demonstrates the telepresence and remote real-time sharing experience provided by Mr (hybrid reality) products. Mesh can be used in any device (mobile phone, tablet, personal computer, virtual reality VR glasses, etc.) to realize the immersive scene feeling and sharing experience through hybrid reality technology. Let people thousands of miles away transmit their own images to the same space for virtual 3D content interaction and mutual communication.Microsoft launched two applications built on the mesh platform: the mesh preview version of user hololens,It can be used for remote collaboration, access the new version of altspacevr supporting mesh, hold meetings and work gatherings in virtual reality, and have enterprise level security; Integrating mesh into teams and dynamics 365, we believe that there will be more innovative application scenarios in the future.
6.Self supervised learning based on seer, a new AI model of Facebook
Facebook researchers recently released a new artificial intelligence model seer,Seer model can use any group of random, unlabeled images on the Internet to learn.Although Facebook’s “breakthrough” is still in its early stage, the team expects that the “breakthrough” will lead to a “revolution” in the field of computer vision. Seer is the abbreviation of self supervised (learning). The training of SEER uses 1 billion public instagram pictures, which have not been artificially planned. That is to say, the image has 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 ultimately achieve the highest accuracy in object detection and other tasks.
1. Emnlp 2020 open domain Q & A of text enhanced knowledge map based on hyperedge fusion
The incompleteness of knowledge base is the key factor to limit the performance of knowledge base question answering system. Outside the knowledge base, the text has more abundant information than the knowledge base, which can be used to make up for the incompleteness of the knowledge base, but at the same time, the text is more difficult to understand for the computer.This paper proposes a new QA method to enhance knowledge base by text. The model enriches entity representation by semantic information contained in text, and updates entity state by graph convolution network.In addition, in order to explore the potential structural information of the text, the author regards the text as the hyperedge of the connected entity to supplement the incomplete relationship in the knowledge base. Hypergraph convolution network is used in text reasoning in hypergraph form. Experiments on webquestion SP benchmark show that the model is effective on different KB.

2. Colling 2020: two way cognitive thinking network for machine reading comprehension
This paper starts from the perspective of simulating human cognitive behavior,By designing neural network to simulate reverse thinking and inertia thinking, the effect of machine reading comprehension model is improved.The author uses human cognitive behavior habits for reference in machine reading comprehension. Therefore, the problems to be solved in this paper are: what behavior habits to learn from, how to learn from, and how to integrate with the machine reading comprehension model. In this paper, from the perspective of simulating human cognitive behavior, through the design of neural network to simulate reverse thinking and inertial thinking, the effect of machine reading comprehension model is improved.
