(English Documents Available)

Angel是一个基于参数服务器(Parameter Server)理念开发的高性能分布式机器学习平台,它基于腾讯内部的海量数据进行了反复的调优,并具有广泛的适用性和稳定性,模型维度越高,优势越明显。 Angel由腾讯和北京大学联合开发,兼顾了工业界的高可用性和学术界的创新性。

Angel的核心设计理念围绕模型。它将高维度的大模型合理切分到多个参数服务器节点,并通过高效的模型更新接口和运算函数,以及灵活的同步协议,轻松实现各种高效的机器学习算法。

Angel基于JavaScala开发,能在社区的Yarn上直接调度运行,并基于PS Service,支持Spark on Angel,未来将会支持图计算和深度学习框架集成。
