WebIt also generalizes various orderless texture descriptors such as the Fisher vector, VLAD and O2P. We present experiments with bilinear models where the feature extractors are based on convolutional neural networks. The bilinear form simplifies gradient computation and allows end-to-end training of both networks using image labels only. http://3dvision.princeton.edu/pvt/depthImproveStructureIO/lib/vlfeat/doc/overview/encodings.html

These vectors allow different features to be assembled into a compact vector . Principal component analysis (PCA) also allows the dimension of the feature vector to be reduced [2,7,21]. greater good prosocial psychopathy
