讲Gradient(Dynamic)节点之前,不得不先说一下Gradient Map节点。 官方文档:The Gradient node remaps the grayscale values from the input, based on a fully customizable color or grayscale gradient. 大体意思就是:Gradient节点可以把灰色渐变重新映射成灰度图或者颜色图,经常被用于Noise转变成颜色图。 而Gradient...
CELLSIZE—The output will be the difference between adjacent cells divided by the cell size of the input. The output unit will be the same as the unit of the x,y coordinates of the input. If the data is in a geographic coordinate system, it will be converted to meters. ...

一个简单的想法是直接用监督学习,把 state 作为 input , 然后 action 的概率分布作为 output,然后游戏玩的好不好(比如获胜了?失败了?)作为 label ,接下来构造一个 Loss function 就能进行学习了。 那么目前最大的问题就在于我们无法得到一个确实的 label,因此强化学习在此就构造了一组 reward,用来衡量动作的好坏...

这里的意思就是说程序默认返回所有forward参数个数的loss,i.e. 为每一个输入参数返回loss,现在我们并不需要给所有参数返回loss,只需要给input tensor返回就够了,其他的直接返回None就ok了。 追求完美的人记得在重写的时候把其他参数也带上,不然有warning。
The returned gradient hence has the same shape as the input array. 1. 2. 3. 如果输入是一维数组,返回同样大小的梯度数组 如果是多维数组,并要求计算多维,那么返回一个列表,包含计算的每一维的梯度,其大小和输入数组一致 计算方式 The gradient is computed using second order accurate central differences ...

DeepExplain supports several methods. The main partition is betweengradient-based methodsandperturbation-based methods. The former are faster, given that they estimate attributions with a few forward and backward iterations through the network. The latter perturb the input and measure the change in out...
This MATLAB function evaluates the gradient of the sum of the outputs of the function approximator object fcnAppx with respect to its inputs.
