查询词典 Frontier

This will cause the final Pareto optimal frontier perform feature subsets with many features erasing and less improvement of classification rate. In order to improve the accuracy of classification, it is necessary to avoid the over trimming of the features. In this study, we propose a constraint based niched Pareto genetic algorithm to adjust the thread of search.

由於在实际问题中，提升分类准确率，常常会比大幅删减使用特徵数来得重要，本研究提出限制型利基柏拉图基因演算法，透过在基因演算法的挑选过程中，增加一准确率限制的手段，调整基因演算法之搜寻方向，以避免特徵的过度删减，并确保分类准确率的提升。

For these selective segments, the geometry optimizations were conducted by using hybrid DFT (B3LYP)methods to find that the structure obturated with H2O was better consistent with the experiment, and then this model would be used to latter calculations, such as the frontier molecular orbital and the NBO charge population analysis.

应用混合的密度泛函B3LYP方法对所选的这些构型进行了量子化学的几何优化，结果表明用-OH2 封闭的构型与实验结果最为接近。

The results show that the HOMO of ZDDP is mainly composed by p atomic orbital of sulphur atoms and the frontier electron densities (subscript occ of them are higher than the oilier elements of ZDDP, thins it can be deduced that the sulphus atoms are the wrist likely points if attack during the surface reaction.

研究表明ZDDP的活性元素为2种位置上的S元素，ZDDP与铁摩擦副作用可能的断键位值是S-P和P=S键。

Contrarily, the lower frontier was found in Chinese IPOs pricing, showing that there is overpricing in Chinese stock market.

应用随机边界模型实证检验了中国新股市场发行定价与新股上市后的市场定价是否存在定价过高或过低的现象。

Relative to the traditional way of predetermining basis functions, basis functions generated by learning algorithms are adapted to image characteristics and hence more efficient in image representation. Basis function-based image representation is currently a frontier research in the field of image processing, involving multiple disciplines such as statistics, geometry, visual physiology etc.

图像信息的描述能力很大程度上取决于基函数的选择，相比传统的预先设定的基函数，通过学习算法获得与图像特性相匹配的基函数能够实现对图像信息更有效的描述。
