One simple way to get a discrete output is to have sign
functions that map the output of a linear regressor to values $\{0,1\}$,
$f(s_i)=sign(s_i)=1$ if $s_i\ge 0$ and 0 if otherwise.
We will encounter this model in our first demonstration of neural networks. Historically it is called the ``perceptron" model in the machine learning
We will encounter this model in our first demonstration of neural networks.
Historically it is called the _perceptron_ model in the machine learning
literature. This model is extremely simple. However, in many cases it is more
favorable to use a ``soft" classifier that outputs
the probability of a given category. This leads us to the logistic function.
