Binary Classifier

Software Methodologies


Binary Classifier

  • Observed response y takes only two possible values + and -

  • Define relationship between $h(x)$ and $y$

  • If larger than the threshold, then set to 1, if less, then set to 0

  • Use the decision rule:

    $$\hat{y}=\left\{\begin{array}{ll} {+,} & {h(x) \geq t} \\ {-,} & {\text { otherwise }} \end{array}\right.$$
