WebJul 22, 2013 · Calculate the hypothesis h = X * theta Calculate the loss = h - y and maybe the squared cost (loss^2)/2m Calculate the gradient = X' * loss / m Update the parameters theta = theta - alpha * gradient In your case, I guess you have confused m with n. Here m denotes the number of examples in your training set, not the number of features. If you don't escape the '\' python interprets your string as it should include a tab (to which the sign is \t). That is exactly why get 'heta' and a tab in front of it.
