How to calculate gradient of output of a neural network with respect to its parameters?I am new to the Deep Learning toolbox. I am working on a Reinforcement Learning problem wherein I need to calculate the derivative of the output of NN with respect to parameters....
..xn>. In my practical application, I have no expression for ff whatsoever, all I can do is given a vector xx, calculate f(x)f(x) via a deterministic experiment. How do I go about calculating the gradient? What specific type of gradient descent would you suggest? Or do you suggest ...

can you tell me please, why you give a decision on that looping, just like "if y < nrow", " if ~= 1", and so on.If
For an outlet using the pressure"blabla"Fvscalarfield, it will call the the gradient from the first B.C. but i dont know how to calculate both gradients in the same B.C. Do i need to use snGrad? and how would be the code for that?
I want to calculategradient feature (central difference)from my filtered data withwindow size=10samples and 50%overlapto previous window. Here what i have done, i am adding here, and also attaching the image for central difference formula and dummy acceleration data. The issue is i am unable...
The cost function is explicitly known, but we still need to calculate . Again, using the chain formula, we obtain: where the n-by-n matrix is the Jacobian of our problem. At this point, the immediate solution is to solve the n-by-n linear system for the ...
Topographic maps reveal the Earth's contour. Contour lines on a map are those lines that reflect a consistent or constant elevation. Slope or gradient is the vertical distance divided by horizontal distance, and channel slope is how far a channel drops o
I want to obtain the gradient of each parameter in the last epoch of training. Is there a way to do so in Keras? Thanks, Ming You can have the outputs of a particular layer by: http://keras.io/faq/#how-can-i-visualize-the-output-of-an-intermediate-layer ...
I am looking for a way to calculate the slope or gradient of data. I need to do the same function as slope (X1:X4, Y1:Y4) in excel but to be able to
