Improved BP neural network combined with semi-supervised algorithm and its application on text classification [PDF]
随着大数据时代的来临,挖掘数据潜在的价值成为了各领域学者、工作者致力于研究的课题之一。文本数据承载着大量的信息,垃圾文本分类作为文本挖掘中经典的课题之一,虽然已经有了长足的发展,但提升垃圾文本分类器的精度一直都是人们追求的目标。BP神经网络模型是一种非常有效的非线性模型,它通过模拟生物神经网络,可以较好的拟合线性不可分的数据,是进行分类问题的常用模型之一。现今,文本数据呈爆炸式增长,呈现数据量大、高纬度、“有标签”数据少“未标签”数据多等特点,传统的BP神经网络已不能很好地解决这些问题。本篇论文中 ...

Research on 3D Head Model Reconstruction Based on Single Front Face Image [PDF]
自从上世纪70年代Parke建立第一个三维人脸模型以来,三维人脸重建就成为了计算机图形学领域中的研究重点,并取得了一定的突破和进展。目前该技术也已被广泛应用于影视动漫、医学图形、人脸识别等领域。而如果有一种手段使得通过后脑勺的照片就可以预测人脸正面特征,这样公安人员侦破违法犯罪的成功率就会大大增加,然而首先研究清楚人脸正面特征与后脑勺之间的关系是实现前者必要的基础和前提条件。目前学者们集中于基于正面图像的三维人脸建模,没有对后脑勺的建模进行详细的研究 ...
