In the field of machine learning, the goal of statistical classification is to use an object's characteristics to identify which class (or group) it belongs to. A linear classifier achieves this by making a classification decision based on the value of a linear combination of the characteristics. An object's … See more If the input feature vector to the classifier is a real vector $${\displaystyle {\vec {x}}}$$, then the output score is $${\displaystyle y=f({\vec {w}}\cdot {\vec {x}})=f\left(\sum _{j}w_{j}x_{j}\right),}$$ where See more 1. ^ Guo-Xun Yuan; Chia-Hua Ho; Chih-Jen Lin (2012).
