Simultaneous Compression and Quantization: A Joint Approach for Efficient Unsupervised Hashing
cs.CV
The two most important requirements for unsupervised data-dependent hashing methods are to preserve similarity in the low-dimensional feature space and to minimize the binary quantization loss. Even though there are many hashing methods that have been proposed in the literature, there is room for improvement to address...

Multi-task, multi-label and multi-domain learning with residual convolutional networks for emotion recognition
cs.CV
Automated emotion recognition in the wild from facial images remains a challenging problem. Although recent advances in Deep Learning have supposed a significant breakthrough in this topic, strong changes in pose, orientation and point of view severely harm current approaches. In addition, the acquisition of labeled da...

Disentangling 3D Pose in A Dendritic CNN for Unconstrained 2D Face Alignment
cs.CV
Heatmap regression has been used for landmark localization for quite a while now. Most of the methods use a very deep stack of bottleneck modules for heatmap classification stage, followed by heatmap regression to extract the keypoints. In this paper, we present a single dendritic CNN, termed as Pose Conditioned Dendri...

Online Action Detection in Untrimmed, Streaming Videos - Modeling and Evaluation
cs.CV
The goal of Online Action Detection (OAD) is to detect action in a timely manner and to recognize its action category. Early works focused on early action detection, which is effectively formulated as a classification problem instead of online detection in streaming videos, because these works used partially seen short...

Automated soft tissue lesion detection and segmentation in digital mammography using a u-net deep learning network
cs.CV
Computer-aided detection or decision support systems aim to improve breast cancer screening programs by helping radiologists to evaluate digital mammography (DM) exams. Commonly such methods proceed in two steps: selection of candidate regions for malignancy, and later classification as either malignant or not. In this...

Machine Learning Methods for Solving Assignment Problems in Multi-Target Tracking
cs.CV
Data association and track-to-track association, two fundamental problems in single-sensor and multi-sensor multi-target tracking, are instances of an NP-hard combinatorial optimization problem known as the multidimensional assignment problem (MDAP). Over the last few years, data-driven approaches to tackling MDAPs in ...

Do deep nets really need weight decay and dropout?
cs.CV
The impressive success of modern deep neural networks on computer vision tasks has been achieved through models of very large capacity compared to the number of available training examples. This overparameterization is often said to be controlled with the help of different regularization techniques, mainly weight decay...

Latent RANSAC
cs.CV
We present a method that can evaluate a RANSAC hypothesis in constant time, i.e. independent of the size of the data. A key observation here is that correct hypotheses are tightly clustered together in the latent parameter domain. In a manner similar to the generalized Hough transform we seek to find this cluster, only...
