, the efficiency will be very low; 2. Appropriate kernel functions need to be found. 3. Sensitive to missing data3. LR applicable conditions: data linear distribution; Advantages: 1. The model is simple, the training speed is fast; 2. Logistic regression is widely used and industrial problems. Disadvantage:1, the form is simple, but the accuracy rate is not very high; 2. It is difficult to deal with data imbalance by relying on all the data; 3. Dealing with nonlinear data is more troublesome.
5-kernel Logistic RegressionLast class, we learnt on soft margin and its application. Now, a new idea comes to us, could weApply the kernel trick to our old Frirend logistic regression?Firstly, let's review those four concepts of margin handling:As we can see, the differences between "hard" and "Soft" are showed from constant C, which are a bit similar to Regularizati MnlSince we define a new factor calledξ, we can use MAX function smoothly express the margin violation:Thus the unconstrained for
