404: Nonlinear, Linear Classification
Mon Jan 1, 2018, in Training, Machine Learning
Nonlinear functions Sometimes data cannot be separated by a simple threshold or linear boundary. We can also use nonlinear functions as a decision boundary. ??? To represent more complex data, we can introduce nonlinearities. Before we do, bear in mind: More complex interactions between features yield solutions that overfit data; to compensate we will need more data. More complex solutions take a greater amount of computational power Anti-KISS The simplest way of adding a nonlinearities is to add various permutations of the original features.
