Hi,i create neural network for classification using nnstart.First i used an input with 9*222 matrix and i got this confusion matrix after training
Then i tried with input with a size of 9*989 but i got this confusion matrix
I want to know why the performance is bad with larger input?should i modify something because i tried to change the number in the hidden layer but it dosen't improve ? Please i need some help
