Deep Rotation Equivariant Network
Recently, learning equivariant representations has attracted considerable research attention. Dieleman et al. introduce four operations which can be inserted into convolutional neural network to learn deep representations equivariant to rotation. However, feature maps should be copied and rotated four times in each layer in their approach, which causes much running time and memory overhead. In ord
Harmonic Networks: Deep Translation and Rotation Equivariance
Abstract Translating or rotating an input image should not affect the results of many computer vision tasks. Convolutional neural networks (CNNs) are already translation equivariant: input image translations produce proportionate feature map translations. This is not the case for rotations. Global rotation equivariance is typically sought through data augmentation, but patch-wise equivariance is m
Kerasの作者@fcholletさんのCVPR'17論文XceptionとGoogleのMobileNets論文を読んだ - Qiita
Kerasの作者@fcholletさんのCVPR'17論文XceptionとGoogleのMobileNets論文を読んだDeepLearningKeras はじめに 最初は、軽量なConvNetに興味があったのでGoogleから出ているMobileNets 1 を読んでいたのだが、その過程でCholletさんのXception論文 2 を（後者は今更）読んだので合わせてまとめる。Cholletさんの論文はなんとなくカジュアルな雰囲気がして面白い。 どちらの論文もpointwise convolutionとdepthwise (separable) convoutionを用いて精度を保ちながらCNNのパラメータ数を削減している。すなわち、精度とパラメータ数のトレードオフを改善していると言える。 Xceptionは、パラメータ削減により、同一のパラメータで大規模な画像認識の高精度化を実現し、
A Brief History of CNNs in Image Segmentation: From R-CNN to Mask R-CNN
At Athelas, we use Convolutional Neural Networks(CNNs) for a lot more than just classification! In this post, we’ll see how CNNs can be used, with great results, in image instance segmentation. Ever since Alex Krizhevsky, Geoff Hinton, and Ilya Sutskever won ImageNet in 2012, Convolutional Neural Networks(CNNs) have become the gold standard for image classification. In fact, since then, CNNs have
MobileNets: Efficient Convolutional Neural Networks for Mobile Vision Applications
We present a class of efficient models called MobileNets for mobile and embedded vision applications. MobileNets are based on a streamlined architecture that uses depth-wise separable convolutions to build light weight deep neural networks. We introduce two simple global hyper-parameters that efficiently trade off between latency and accuracy. These hyper-parameters allow the model builder to choo

Towards the Limit of Network Quantization
Network quantization is one of network compression techniques to reduce the redundancy of deep neural networks. It reduces the number of distinct network parameter values by quantization in order to save the storage for them. In this paper, we design network quantization schemes that minimize the performance loss due to quantization given a compression ratio constraint. We analyze the quantitative
Predicting lung cancer
Predicting lung cancer The Data Science Bowl is an annual data science competition hosted by Kaggle. In this year’s edition the goal was to detect lung cancer based on CT scans of the chest from people diagnosed with cancer within a year. To tackle this challenge, we formed a mixed team of machine learning savvy people of which none had specific knowledge about medical image analysis or cancer pre
Is Second-order Information Helpful for Large-scale Visual Recognition?
By stacking layers of convolution and nonlinearity, convolutional networks (ConvNets) effectively learn from low-level to high-level features and discriminative representations. Since the end goal of large-scale recognition is to delineate complex boundaries of thousands of classes, adequate exploration of feature distributions is important for realizing full potentials of ConvNets. However, state
Tube Convolutional Neural Network (T-CNN) for Action Detection in Videos
Deep learning has been demonstrated to achieve excellent results for image classification and object detection. However, the impact of deep learning on video analysis (e.g. action detection and recognition) has been limited due to complexity of video data and lack of annotations. Previous convolutional neural networks (CNN) based video action detection approaches usually consist of two major steps

Embedding Watermarks into Deep Neural Networks
Deep neural networks have recently achieved significant progress. Sharing trained models of these deep neural networks is very important in the rapid progress of researching or developing deep neural network systems. At the same time, it is necessary to protect the rights of shared trained models. To this end, we propose to use a digital watermarking technology to protect intellectual property or
