MATLAB: Gradient Descent Neural Network

Deep Learning Toolboxneural networks

Hi,

I am using neural network toolbox. I am really new in ANN. My Question is, what is the performance value indicates?Attached is the image. Please apologize my bad English and the Image format if it is not proper.

Thanks a lot

Best Answer

1. Image is not attached

2. Type net = net % w/o ending semicolon and find

 net.performanceFcn = 'mse' % i.e., the average squared error

3. For details, type

 help mse
   and/or
 doc mse

Hope this helps

Thank you for formally accepting my answer

MATLAB: Shallow Neural Network with Stochastic Gradient Descent

The following command lists all the training functions available:

help nntrain

From the output I can see that stochastic gradient descent is not there in case of shallow neural networks.

Since that you want a simple Multilayered ANN, refer to List of Deep Learning Layers & use appropriate layer from Input Layers followed by fullyconnectedLayers & appropriate Output Layer. Then use the 'sgdm' in trainingOptions.

Also refer to Deep Learning Toolbox — Examples
