Generalized RBF feature maps for Efficient Detection

ject detectors on the VOC 2007 dataset [8]. We show that the approximate feature map can improve performance significantly over that of the original additive kernels. An alternative to the method we propose is to employ Nyström-type approximations [1,3,22] to obtain linear feature maps, but these require a data dependent training step that we avoid here. 2 Kernels and feature maps. This ...
