This function takes values on the entire real axis. In the case of logistic regression, however, the labels \( y_i \) are discrete variables. One simple way to get a discrete output is to have sign functions that map the output of a linear regressor to \( \{0,1\} \), \( f(s_i)= \) sign$(s_i) = 1$ if \( s_i\ge 0 \) and 0 if otherwise. Indeed, this is commonly known as the "perceptron" in the machine learning literature. This model is extremely simple, and it is favorable in many cases (e.g. noisy data) to have a ``soft" classifier that outputs the probability of a given category. For example, given \( \mathbf{x}_i \), the classifier outputs the probability of being in category \( m \). One such function is the logistic (or sigmoid) function:
