Mix-and-Match Tuning for Self-Supervised Semantic Segmentation
cs.CV
Deep convolutional networks for semantic image segmentation typically require large-scale labeled data, e.g. ImageNet and MS COCO, for network pre-training. To reduce annotation efforts, self-supervised semantic segmentation is recently proposed to pre-train a network without any human-provided labels. The key of this ...

Spatial PixelCNN: Generating Images from Patches
cs.CV
In this paper we propose Spatial PixelCNN, a conditional autoregressive model that generates images from small patches. By conditioning on a grid of pixel coordinates and global features extracted from a Variational Autoencoder (VAE), we are able to train on patches of images, and reproduce the full-sized image. We sho...

Fully-Convolutional Measurement Network for Compressive Sensing Image Reconstruction
cs.CV
Recently, deep learning methods have made a significant improvement in com- pressive sensing image reconstruction task. However, it still remains a problem of block effect which degrades the reconstruction results. In this paper, we pro- pose a fully-convolutional network, where the full image is directly measured with...

Three-Stream Convolutional Networks for Video-based Person Re-Identification
cs.CV
This paper aims to develop a new architecture that can make full use of the feature maps of convolutional networks. To this end, we study a number of methods for video-based person re-identification and make the following findings: 1) Max-pooling only focuses on the maximum value of a receptive field, wasting a lot of ...

A Pitfall of Unsupervised Pre-Training
cs.CV
The point of this paper is to question typical assumptions in deep learning and suggest alternatives. A particular contribution is to prove that even if a Stacked Convolutional Auto-Encoder is good at reconstructing pictures, it is not necessarily good at discriminating their classes. When using Auto-Encoders, intuitiv...

An Ensemble of Deep Convolutional Neural Networks for Alzheimer's Disease Detection and Classification
cs.CV
Alzheimer's Disease destroys brain cells causing people to lose their memory, mental functions and ability to continue daily activities. It is a severe neurological brain disorder which is not curable, but earlier detection of Alzheimer's Disease can help for proper treatment and to prevent brain tissue damage. Detecti...

Lung Nodule Classification by the Combination of Fusion Classifier and Cascaded Convolutional Neural Networks
cs.CV
Lung nodule classification is a class imbalanced problem, as nodules are found with much lower frequency than non-nodules. In the class imbalanced problem, conventional classifiers tend to be overwhelmed by the majority class and ignore the minority class. We showed that cascaded convolutional neural networks can class...

Take it in your stride: Do we need striding in CNNs?
cs.LG
Since their inception, CNNs have utilized some type of striding operator to reduce the overlap of receptive fields and spatial dimensions. Although having clear heuristic motivations (i.e. lowering the number of parameters to learn) the mathematical role of striding within CNN learning remains unclear. This paper offer...

StrassenNets: Deep learning with a multiplication budget
cs.LG
A large fraction of the arithmetic operations required to evaluate deep neural networks (DNNs) consist of matrix multiplications, in both convolution and fully connected layers. We perform end-to-end learning of low-cost approximations of matrix multiplications in DNN layers by casting matrix multiplications as $2$-lay...
