چکیده

Automated content-based search for arbitrary cuneiform signs in photographic reproductions is a challenging task the analysis of ancient documents, central component which reliable sign classification. We present an illumination-based approach to generate synthetic training data classification via deep neural networks overcome common issues with transferability machine learning results. Starting from negative impact illumination variations processed data, we employ augmentation two-dimensional (2D) generated annotated 3D datasets. demonstrate that our method able high visual variance most digitized 2D and achieve invariant generalization. The effectiveness evaluated by its successful application several subsets script dataset originally poor mutual Furthermore, show sufficient sampling space mostly removes necessity match specific target conditions. practical applicability validated applying it larger dataset, raising overall accuracy 4 percentage points 90%, resulting error reduction 28.5% when compared results without proposed augmentation.

Multi-column deep neural network for traffic sign classification

We describe the approach that won the final phase of the German traffic sign recognition benchmark. Our method is the only one that achieved a better-than-human recognition rate of 99.46%. We use a fast, fully parameterizable GPU implementation of a Deep Neural Network (DNN) that does not require careful design of pre-wired feature extractors, which are rather learned in a supervised way. Combi...

Image Augmentation using Radial Transform for Training Deep Neural Networks

Deep learning models have a large number of free parameters that must be estimated by efficient training of the models on a large number of training data samples to increase their generalization performance. In real-world applications, the data available to train these networks is often limited or imbalanced. We propose a sampling method based on the radial transform in a polar coordinate syste...

Deep Neural Network Architectures for Modulation Classification

In this work, we investigate the value of employing deep learning for the task of wireless signal modulation recognition. Recently in [1], a framework has been introduced by generating a dataset using GNU radio that mimics the imperfections in a real wireless channel, and uses 11 different modulation types. Further, a convolutional neural network (CNN) architecture was developed and shown to de...

Selective Classification for Deep Neural Networks

Selective classification techniques (also known as reject option) have not yet been considered in the context of deep neural networks (DNNs). These techniques can potentially significantly improve DNNs prediction performance by trading-off coverage. In this paper we propose a method to construct a selective classifier given a trained neural network. Our method allows a user to set a desired ris...
