Abstract

Automatically assigning semantically relevant tags to an image is an important task in machine learning. Many algorithms have been proposed to annotate images based on features such as color, texture, and shape. Success of these algorithms is dependent on carefully handcrafted features. Deep learning models are widely used to learn abstract, high level representations from raw data. Deep belief networks are the most commonly used deep learning models formed by pre-training the individual Restricted Boltzmann Machines in a layer-wise fashion and then stacking together and training them using error back-propagation. In the deep convolutional networks, convolution operation is used to extract features from different sub-regions of the images to learn better representations. To reduce the time taken for training, models that use convex optimization and kernel trick have been proposed. In this paper we explore two such models, Tensor Deep Stacking Network and Kernel Deep Convex Network, for the task of automatic image annotation. We use a deep convolutional network to extract high level features from raw images, and then use them as inputs to the convex deep learning models. Performance of the proposed approach is evaluated on benchmark image datasets.
