Mining influence in evolving entities is an important but challenging task, partly due to complex nature of it. In this paper, we mainly focus on the following problems on it with respect to stock market: (1) How to identify pairs of stocks that influence one another; (2) How to quantify the influence and capture group effects and dynamic nature of influence of each stock; (3) How to adopt approximate...
A new acoustic model based on deep neural network (DNN) has been introduced recently and outperforms the conventional Gaussian mixture model (GMM) in speech recognition on several tasks. However, the number of parameters required by a DNN model is much larger than that of its counterpart. The excessive cost of computation cumbers the implementation of DNN in many scenarios. In this paper, a DNN-based...
In order to resolve the issue of large-scale assembly for quasi-LIGA micro-parts, the purpose of this paper is to propose a novel method of orthogonal optical precise alignment. The micro-assembly experiment system set-up was constructed according to the principle of the orthogonal precise alignment. One single-position consists of three components: 3-DOF micro motion worktable, micro force feedback...
Theoretical analysis of the precision ensuring mechanism of reconfigurable machine interface using over-positioning technology was thoroughly presented. Based on the obtained rule of over-positioning precision, positioning pin number and interfere probability, the concept of two-state positioning aiming at the positioning difficulty of rigid over-positioning machine interface was proposed. In addition,...
Geostationary imagers such as the Advanced Baseline Imager (ABI) proposed for the next generation of Geostationary Operational Environmental Satellites (GOESs), i.e., GOES Series R and beyond, and the spinning enhanced visible and InfraRed Imager (SEVIRI) onboard METEOSAT 8 provide atmospheric total column ozone (TCO) with high temporal (better than 15 min) and spatial (better than 5 km) resolutions...
