One-Class Classification with Extreme Learning Machine

Figure 3

The upper row shows the boundaries of the method with random feature mappings and the bottom row shows the boundaries of the method with Gaussian kernel. Parameter of the method with random feature mapping from left to right is 2¹¹, 2⁶, and 2⁹. Parameters of the method with Gaussian kernel from left to right are (2², 5.76), (2⁰, 2.81), and (2⁻⁴, 1.55).
