ANNALS OF HUMAN GENETICS 2009年 第3期73卷 346-359页
作者: Shi, Min Umbach, David M. Weinberg, Clarice R. NIEHS Biostat Branch NIH DHHS Res Triangle Pk NC 27709 USA
Estimating haplotype relative risks in a family-based study is complicated by phase ambiguity and the many parameters needed to quantify relative risks for all possible diplotypes. This problem becomes manageable if a... 详细信息

IEEE International Geoscience and Remote Sensing Symposium
作者: Blanchart, Pierre Datcu, Mihai CNRS UMR 5141 GET Telecom Paris LTCI F-75013 Paris France
In this paper, we present a semi-supervised method for auto-annotating image collections and discovering unknown structures among them. The approach relies on the existence of only a small training database of annotat... 详细信息

Spring Conference of the International-Association-of-Computer-Science-and-Information-Technology
作者: Tsai, Chieh-Yuan Chiu, Chuang-Cheng Yuan Ze Univ Dept Ind Engn & Management Chungli Taiwan
Case-based reasoning is a problem-solving technique commonly seen in artificial intelligence. A successful CBR system highly depends on how to design an effective case retrieval mechanism. The K-nearest neighbor (KNN)... 详细信息
