你需要实现步骤1-4在一个循坏里面,一次处理一个样本。具体来说,你需要实现for循坏,用for i = 1:m然后讲步骤1-4放在这个循环里面,那么第i次迭代就是计算第i个样本。然后第五步会将所有的梯度值相加在除m,获得了神经网络的代价函数的梯度。 将第输入层的值设置成第t个训练样本。先进行前向传播,计算出第2...

Found a workaround to use until this bug will get solved. You can still train the Actor with GPU and the Critic with CPU. With this configuration you can also still use the parallel pool for gathering multiple experiences faster. This reduced my training time in comparison to just trai...
For single GPU training with the"auto"or"gpu"options, by default, MATLAB uses the GPU device with index1. You can use a different GPU by selecting the device before you start training. UsegpuDevice(Parallel Computing Toolbox)to select the desired GPU using its index: ...
出于一些原因使用多gpus和多cpus可能会带来更高的性能但是出于另外一些原因cpus资源有可能会拖gpus的后腿所以单独使用gpus会更快设置usegpu为only来限制workers使用特定的gpus (总结篇)使用MATLABGPU加速计算MATLAB并行计算与分布式服务器MATLAB技术论坛 本帖最后由 蓝云风翼 于 2013-12-18 17:28 编辑 注: 利用gpu...
