the value to differentiate must always be real, and therefore the function can never be complex analytic. Instead, the derivative is computed such that the returned gradient points in the direction of steepest ascent, as seen in the plot. This...
We use gradients computed via EventProp to train networks on the Yin-Yang and MNIST datasets using either a spike time or voltage based loss function and report competitive performance. Our work supports the rigorous study of gradient-based learning algorithms in spiking neural networks and provides...
Define the functiongradFun, listed at the end of this example. This function callscomplexFunand usesdlgradientto calculate the gradient of the result with respect to the input. For automatic differentiation, the value to differentiate — i.e., the value of the function calculated from the input...
Second, in case that the enironment is too complex (or time-consuming) to define, how can I compute the gradient of the output of the policy network, with regards to each of its parameters (weights and bias), like done in the example--- It seems tha...

features= forward(detector,dlX)computes the output features of the network during training given the input datadlX. [features,activations] = forward(detector,dlX)also computes the activations of the network that you can use for modelling the gradient loss. ...
the elements of the output correspond to the scores for each class. The order of the scores matches the order of the categories in the training data. For example, if you train the neural network using the categorical labelsTTrain, then the order of the scores matches the order of the cate...
The network can then learn from those errors using an algorithm, such as the stochastic gradient descent algorithm, to update the weights of the of the neural network. FIGS. 11A & 11B illustrate an exemplary convolutional neural network. FIG. 11A illustrates various layers within a CNN. As ...
