The main job of an activation function is to introduce non-linearity in a neural network. One way to look at this is that without a non-linear activation function, a neural network will behave just ...

Kernel machines are a class of pattern-analysis algorithms, the most well-known member of which is the support vector machine (SVM). Many classical classification algorithms work straightforward when ...

Often in economics a linear function cannot explain the relationship between variables. In such cases a non-linear function must be used. Non-linear means the graph is not a straight line. The graph ...
