Summary:The invention discloses a method for updating global parameters in a parameter server. The method comprises the steps of: setting parameter server-related parameters first, initializing the global parameters, then downloading and preprocessing the training data from the database. Then the local parameters of each working node are calculated by using the preprocessed training parameters and the initialized global parameters. Finally, the local parameters are sent back to the parameter server, and the global parameters are updated iteratively through the parameter server. 本发明公开了种参数服务器中全局参数的更新方法，先设置参数服务器相关参数，并对全局参数初始化，然后从数据库中下载训练数据，并进行预处理，再利用预处理后的训练参数和初始化后的全局参数计算各个工作节点的本地参数，最后将本地参数回传给参数服务器，通过参数服务器进行迭代更新全局参数。
