Deep Neural Networks Under

Abstract

In recent years, deep architectures have been used for transfer learning with state-of-the-art performance in many data sets. The properties of their features remain, however, largely unstudied under the transfer perspective. In this work, we present-an extensive analysis of the resiliency of feature vectors extracted front deep models, with special focus on the trade-off between performance and compression rate. By introducing perturbations to image descriptions extracted from a deep convolutional neural network, we change their precision and number of dimensions, measuring how it affects the final score. We show that deep features are more robust to these disturbances when compared to classical approaches, achieving a compression rate of 98.4%, while losing only 0.88% of their original score for Pascal VOC 2007.
