I have tried to train a neural network for a simple x^2 function
- I developed training data in excel. First column (X) is =RANDBETWEEN(-5,5) i.e random integer between -5 and 5
- Second column simply squares first column
- And third column, my output 'y' column is 0 or 1. 0 if second column is less than 12.5 else 1
I made 850 training examples and used the first column as 'X' and third column as 'y'
However I am only able to get a training accuracy of 63%!
Where could I have gone wrong? I changed input_layer to 1 and tried hidden units between 5 and 35. Tried regularization lambda 0 to 2 but still only 63% accuracy! Where could I have gone wrong?
My predict function is p = 1 if h2(i)>0.5 else 0.
Any help will be much appreciated! :-)
I also noticed that my neural network's output is 0.3XXX for all training examples...how is this possible??
