Hi. I am trying to create an Artificial Neural Network in Deep Network Designer where there will be input layer, hidden layers, output hidden layers and an output layer. My input values are a 8C x 368R matrix and my output value is a 1C x 368R matrix. I would like to train my values with a 70% training data, 15% validation data, and 15% testing data just like ANN. And also, I would like to train it using Levenberg - Marquardt algorithm. But, I won't use the >>nnstart tool. Because I will use it just for the validation of my data. I would like to use Deep Network Designer to simulate an >>nnstart like feature. Is there any way that I can import excel data file in Deep Network Designer to run an ANN feature? Thank you.
