Therefore, experimental results prove that the accuracy rate of a whole text classification system can be effectively improved by means of the novel method.丁泽亚张全缪建明CN102622373A * Jan 31, 2011 Aug 1, 2012 中国科学院声学研究所 一种基于TF*IDF算法的统计学文本分类系统及方法...
英文: A direct iteration method in solving normal equations by means of bidirectional asynchronous integral has been successfully exploited, so that it can efficiently overcome the difficulty in solving two-point boundary value problems resulting from inverse s 中文: 文中提出双向异步积分迭代求解正则方...
$ELAY !-V The fixed off time delay circuit is implemented by connecting the gate drive (GD) output to the ZCD input by means of a diode D5 in series with R11 and C7 (in parallel), and ZCD to ground with R18 and C8 in parallel. There is a clamp circuit behind the ZCD...
Ultrathin meta-optics offer unmatched, multifunctional control of light. Next-generation optical technologies, however, demand unprecedented performance. This will likely require design algorithms surpassing the capability of human intuition. For the adjoint method, this requires explicitly deriving gradients,...
For many practical scenarios, training data might not be available. Some unsupervised approaches can also be used to model for this problem. Using K-means algorithm to group the questions in clusters and then classifying the similar/dissimilar based on that can also be employed. A simple approach...
This means that the simulations must run at the same time (or faster) than the data are collected. While this is not always true (as in weather forecasting, for instance, where collected data are not usually incorporated to the simulations), most applications require different forms of real-...
This means that the algorithm is continually changing its exploration/exploitation capabilities depending on the iterations. This policy allows escaping from entrapment in local minima. In the case study the CP version with a variable time step has shown to be a very efficient algorithm. 3. ...
Two phaseless inverse problems for elliptic equations are considered. We assume that information related to modulus of full fields, which consist of sums of incident and scattering fields, is given. These full fields are the interference fields generated
