Having such a toolbox to make our models pareto-optimal has the following benefits: Sustainable Server-Side Scaling Training and deploying large deep learning models is costly. While training is a one-time inference can be run completely on the user’s device without the need to send the input data to the server-side. New Applications Efficiency would also enable applications that couldn’t have otherwise been device. This further reduces the available resources for a single model. This could happen on the server-side where multiple models are co-located on the same machine, or could be in an app where different

的梯度信息并不直接用于更新 Worker 的 Actor-Critic 网络，而是提 交到 Global Network 更新。具体地，在 Worker 类初始化阶段，获得 Global Network 传入的 server 对象和 opt 对象，分别代表了 Global Network 模型和优化器；并创建私有的 ActorCritic 网络类 client 和交互环境 env。代码如下： class Worker(threading def __init__(self, server, opt, result_queue, idx): super(Worker, self).__init__() self.result_queue = result_queue # 共享队列 self.server = server # 中央模型 self.opt # 梯度提交到 server，在 server 上更新梯度 self.opt.apply_gradients(zip(grads, self.server.trainable_weights))
