本文通過球面極坐標將點雲曲面的幾何信息及表面屬性信息映射到二維圖象中去。From ibm canadas global services, i wish to acknowledge james liu for the detailed manual mapping of the lookup dictionary and a very thorough border testing of the function, and, last but not least, jammie lee, for coordinating the team effort and for the positive feedback to move it forward and bring it to fruition
我要感謝同在ibm加拿大全球服務分公司工作的james liu ，是他手工完成了查找字典的詳細映射，並對函數做了非常徹底的邊界測試。最後一點，也是最重要的一點，感謝jammie lee為協調小組工作所作出的努力，他的積極反饋使得小組工作順利發展並產生成果。Adopting the globe pole mapping method of space analytic geometry, forming a topological mapping model from the high dimensionality vector to the low one, and then realizing a corresponding mapping from the rectangular matrix high dimensionality space text set to the low dimensionality space text set, finally, composing the corresponding arithmetics, accordingly solving the problem of nonlinear dimensionality reduction for text mining effectively, and overcoming some drawbacks in the former researches
摘要採用了空間解析幾何中的球極映射方法，形成高維向量到低維向量的拓撲變換模型，實現了矩陣形式的高維空間文本集合到低維空間文本集合的一一映射，編制了相應的演算法，從而有效地解決了文本挖掘中的非線性降維問題，克服了以往研究中的缺陷。分享友人
