I was doing multilayer neural network using newff function. size of input = 3 x 150 (3 input data, 150 samples) size of target = 1 x 150 net = newff([minmax(Inputs)],[10,1],{'logsig' 'logsig'}); 10 neurons in hidden layer and 1 neuron in output layer so the size of input weight in hidden layer = 3 x 10, a = weight; (the value of weight is 50 and above) a = net.IW{1,1};
Why a = net.IW{1,1}; will return negative value and the value is very small?
