Hi I am quite new to using Mathematica for machine learning purposes, hence this might be a basic question. In the following code I am using a trained neural network to output the rotation angle of a qubit (after training in for a set of discrete rotations). After training I send the training data through as a test. The output is as expected. The neural network runs, but I am interested in how to use the bulit-in ValidationSet function to avoid overfitting. My NetTrain function is of the following form: trainedNet = NetTrain[net2, trainingData2, MaxTrainingRounds -> 70000] Can anyone advise ..read more

I have a problem which I can't solve properly in Mathematica: A beam tilts at an edge; initially, it adheres, then it slides. First, the transition from adhering to sliding and then from sliding to the lifting of the edge should be determined. This can be accomplished using the center of mass theorem, angular momentum theorem, and the condition of adhesion. For setting up the differential equation, please refer to the attached document. The first task to find out the time and angle at which the beam starts to slide is correct in my opinion but I do not get plausible values for the second task ..read more

Hi, I have a matrix representing more than one physical properties and hence a vast difference b/w numerical values of the elements, say from 10^12 - 10^-9. I get the o/p when I do any matrix operation on the matrix but with a error message "Result for Inverse of badly conditioned matrix ..... may contain significant error". Perhaps, this "error identification" is also effecting the processing speed of Mathematica as well. How can I get rid of this error message, and tell Mathematica that everything is normal in these numbers. Could there be a better way to deal with such matrices with large d ..read more
