14th Annual Conference of the International Speech Communication Association, INTERSPEECH 2013
作者: Wiesler, Simon Li, Jinyu Xue, Jian Computer Science Department Human Language Technology and Pattern Recognition RWTH Aachen University 52056 Aachen Germany Microsoft Corporation Redmond WA 98052 United States
Context-dependent deep neural network HMMs have been shown to achieve recognition accuracy superior to Gaussian mixture models in a number of recent works. Typically, neural networks are optimized with stochastic grad... 详细信息

International Workshop on Frontiers in Handwriting recognition
作者: Michal Kozielski Jens Forster Hermann Ney Human Language Technology and Pattern Recognition Group Chair of Computer Science 6 RWTH Aachen University Aachen Germany
In this paper, we extend the concept of moment-based normalization of images from digit recognition to the recognition of handwritten text. Image moments provide robust estimates for text characteristics such as size ... 详细信息

arXiv 2018年
作者: Bahar, Parnia Brix, Christopher Ney, Hermann Human Language Technology and Pattern Recognition Group Computer Science Department Rwth Aachen University AachenD-52056 Germany
This work investigates an alternative model for neural machine translation (NMT) and proposes a novel architecture, where we employ a multi-dimensional long short-term memory (MDLSTM) for translation modeling. In the ... 详细信息
