Depth-Adaptive Computational Policies for Efficient Visual Tracking
cs.CV
Current convolutional neural networks algorithms for video object tracking spend the same amount of computation for each object and video frame. However, it is harder to track an object in some frames than others, due to the varying amount of clutter, scene complexity, amount of motion, and object's distinctiveness aga...

Denoising Adversarial Autoencoders: Classifying Skin Lesions Using Limited Labelled Training Data
cs.CV
We propose a novel deep learning model for classifying medical images in the setting where there is a large amount of unlabelled medical data available, but labelled data is in limited supply. We consider the specific case of classifying skin lesions as either malignant or benign. In this setting, the proposed approach...
