NettetSorted by: 59. Logistic regression is linear in the sense that the predictions can be written as. p ^ = 1 1 + e − μ ^, where μ ^ = θ ^ ⋅ x. Thus, the prediction can be written in terms of μ ^, which is a linear function of x. (More precisely, the predicted log-odds is a linear function of x .) Conversely, there is no way to summarize ...

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 … Se mer 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 Se mer • Backpropagation • Linear regression • Perceptron • Quadratic classifier • Support vector machines Se mer 1.
