Abstract

The recent success in visual recognition using deep neural network has stimulated the research in exploring new network architectures. Building feature encoders on top of convolutional features is a popular approach for this goal. I will introduce the bilinear CNNs, an architecture that efficiently represents an image as a pooled outer product of two CNN features, and its applications on fine-grained classification and texture recognition. The talk will: (1) introduce a general formulation of bilinear model for classification, (2) derive a family of end-to-end trainable bilinear models that generalize classical image representations, (3) discuss the dimensionality reduction techniques on bilinear models, (4) evaluate the performance on fine-grained recognition and texture recognition tasks, and (5) visualize the attributes learned by the models. The source code for the complete system is available at http://vis-www.cs.umass.edu/bcnn
