Neural machine translation (NMT) heavily relies on its encoder to capture the underlying meaning of a source sentence so as to generate a faithful translation. However, most NMT encoders are built upon either unidirectional or bidirectional recurrent neural networks, which either do not deal with future context or simply concatenate the history and future context to form context-dependent word representations,...
Sickbed arrangement is an important part of daily management in the hospital. Since the service time for different type of patients varies, the queuing system here, with multi-random input flow, can not be solved accurately by using classical queuing theory. Based on the analysis of patient information, we apply the simulation method into the sickbed arrangement system, and take the average waiting...
We propose two new analytical polarization ratio (PR) models based on the RADARSAT-2 Quad-Polarization (HH+VV+HV+VH) observations over the ocean. One is a function of incidence angle only and the other has additional dependence on wind speed. Comparisons are presented with theoretical and empirical PR models from the literature. The new PR model with wind speed and incidence angle dependence is shown...
Whether institutional investors or individual investors need to select valuable stocks form stock markets. In this paper, analytic hierarchy process(APH) is utilized to build a comprehensive industry evaluation system by considering various factors that affect the industry. Then we combine factor analysis and technique of order preference by similarity to ideal solution(TOPSIS) to evaluate companies...
Through analyzing the simulation process of the brake test-bed, using a single-loop and a double-loop control model, this paper proposes that regarding the drive current as the control point, and on this basis, establishing a non-linear control model based on single neuron self-adaptivity. Then, this paper analysis these models using computer simulation. At last, the results shows that under the self-adaptive...
The nurturing of innovative talent is the basis of a national increase scientific and technological innovation. How to cultivate talents with innovative consciousness and innovative abilities is the major concern of Chinese higher education. Based on in-depth analysis of mathematical modeling training and contest in this paper, we came to the conclusion that mathematical modeling training and contest...
The purpose of this paper is to improve the security and the anti-errors-proliferation character of image encryption. Based on the theory of S-box in AES, we put forward a new standard algorithm. After that, by introducing the chaos random sequence, two improved image encryption algorithms were created. The method used by the first one was that a variety of S-boxes were selected for the substitution...
