Beijing on December 20, Linux Foundation's top foundations for the field of AI --LF AI Foundation (Linux Foundation Artificial Intelligence Foundation) officially announced that Tencent open source projects Angel graduated from LF AI Foundation, is the first from China LF AI graduate Foundation open source projects. This means that, Angel recognized global technology experts, one of the world's top AI open source projects.
Ibrahim Haddad, executive director of LF AI Foundation, said: "Angel from hatching to the process of graduation, we can see the stunning Angel in terms of new features and application scenarios perfect landing speed with the release of version 3.0, Angel in function. applicability and contribution to the community and so have very good performance. this is the whole AI open source community has taken a big step in the direction of maturity and have the industrial capacity. "
Angel is Tencent's first open-source AI project, launched in late 2016, 2017 revenue. As the third generation of machine learning for high-performance computing platform, Angel is committed to solving large sparse data model training and large-scale map data analysis problems. Tencent become one of the founding members of LF AI Platinum Foundation in 2018, and in the same year contributed to the Angel Foundation open source project.
Vice president of Tencent cloud, Jiang Jie, general manager of Tencent data platform, said: "Tencent is committed to open source, and open-source developers to build eco realize sharing of results, has become the most comprehensive open source big data field of company we are pleased to see. Angel to successfully graduate from LF AI Foundation, under the guidance and developers to build the foundation to complete the technological leap from a single platform to model training full-stack machine learning platform, which also combines with Tencent large batches of data streams, ABC closely fit the future direction of integration. graduation is a new beginning Angel, in the future we will further open Angel core competence in the field of view of the federal computing and learning. "
According to LF AI Foundation director, Tencent AI expert Xiao Han introduced, LF AI Foundation have very strict rules on the graduation process open source project, based on technical content, open source ecosystem, community interaction and other dimensions of the project, a rigorous assessment of project maturity the final vote by the Board of Directors can be allowed to graduate. Graduate from LF AI, mean that the project has been recognized by global technology experts as the most top AI open source projects.
Angel in the incubation process in the Foundation's rapid development, and completed from version 2.0 to version 3.0 of the cross, from a simple model training system evolved to include full-stack machine learning platform from automatic feature to the model engineering services.
Angel & LFAI
Angel characterized Spark developed based engineering modules, enhanced features Spark selection function, wherein the cross and re-use the index to achieve the automatic feature generation. These components can be seamlessly integrated into Spark pipeline. In order to make the whole system more intelligent, Angel 3.0 adds ultra-parameter adjustment function.
In the model service, Angel 3.0 provides components Angel Serving a cross-platform, not only to meet their own needs Angel, can also provide a model for other platforms services. In ecological terms, Angel also try to shared server parameters (PS) capabilities to other computing platform, we have completed the construction of Spark On Angel and PyTorch On Angel two platforms.
Figure computing architecture
在3.0版本中，Angel重点研发了图机器学习功能，包括图表示和图神经网络学习模型，同时提供预处理、图挖掘等端到端数据处理能力，具有丰富的算法库，提供了同构图、异构图多种图计算范式和不同种类的图算法。经过腾讯内部业务的大规模实践，Angel在图算法性能上同样表现出众，例如十亿节点、千亿边规模的图结构，运行算法时能以Spark GraphX三分之一的计算资源，达到十倍处理性能。
图计算性能对比
除了技术功能上的完善，Angel在社区生态上也日趋成熟。据了解，在全行业Angel拥有超过 100家公司和机构用户，其中包括微博、华为、微众银行、小米、滴滴等大型互联网企业。基于Angel构建的一站式机器学习应用平台智能钛TI，支持了包括微信支付、腾讯广告、微视等在内的诸多腾讯内部产品，同时也通过腾讯云对外开放为更多行业企业提供服务。
截止目前，Angel在GitHub上已经获得了5500 Star，1400 Fork，在技术、应用、生态等方面的优秀表现均得到了开源社区的认可。此前在腾讯2019 Techo开发者大会上，蒋杰还宣布了资源管理平台核心TKE和分布式数据库TBase的正式开源。腾讯正在成为大数据领域开源最全面的公司。
开源协同是当前腾讯最重要的技术战略之一。在今年的重庆智博会上，腾讯公司董事会主席兼首席执行官马化腾专门提及了对开源的重视，他表示，腾讯希望在科研领域投入更多力量，将通过内外部开源等方式，积极参与“全球科技共同体”的共建。
As of November 2019, only on Github, Tencent open source 91 projects, there are more than 1000 contributors involved, get more than 260,000 Star number, contribute standings among the highest in the world Github company. Tencent also joined the Linux, Apache and other 9 major open source foundations, and the highest level of membership. Open Source Foundation, which specialized in the field of artificial intelligence LF AI Foundation is sponsored by the Linux Foundation, aims to promote and organize AI open-source platform and tools to participate in the construction of IP in access to intellectual property rights, create open-source ecosystem for sustainable development of AI .
2018, Tencent influence due to technical excellence in the field of open source AI, invited as an initial platinum member LF AI Foundation joined with the Board of Directors and Technical Advisory Committee seats, and high performance in the same year donated to the Foundation distributed machine learning platform Angel.
