Help needed with neural network
Hello people, I am doing a project that involves making a neural network. I get data sets for that neural network from some other program that i use to generate 2 vectors: mdf that is <1x195> and rms that is also <1x195> which i merge into one input like inp1=[mdf;rms] so it's dimensions are <2x195>.
