1) conditional homogeneity assumption
条件同质性假设
3) conditional independence assumption
条件独立性假设
1.
By giving distinct classification rule to each sample,decision forest rather than decision tree is constructed to automatically determine relatively independent attribute subset,and based on this we integrate submodel by applying conditional independence assumption.
提出一种基于决策森林构造的多重子模型集成方法,通过对每个样本赋予决策规则,构造决策森林而非单个决策树以自动确定相对独立的样本子集,在此基础上结合条件独立性假设进行模型集成。
4) hypothetical conditions
假设性条件句
1.
Compared with hypothetical conditions, open conditions, introduced by if, are more frequently used, with different meanings and various combinations of verb forms both in main and subordinate ckuses.
与假设性条件句相比,开放性If-条件句具有使用频率高、形式不固定、语义变化大等特点。
5) hypothesis of conditional independence
条件独立性假设
1.
We proved that the hypothesis of conditional independence between TM bands was successful, and analyzed the feasibility of applying Na ve Bayesian Networks to the classification of multi-spectral image through experiment.
用基于启发式搜索的结构学习算法,学习得到多光谱影像的贝叶斯网络结构,分析了TM的波段(特征)间条件独立性假设的合理性,给出了贝叶斯推理中后验概率计算的公式,并通过和最大似然法对比试验分析了简单贝叶斯网络应用于多光谱影像分类的优势。

2.
Scholars have pointed out some defects of the model, but nobody has tried to analyze the defects of hypothesis of the model.

卵巢混合性生殖细胞-性索间质性肿瘤
本瘤1921年首次由Masson描述，直到1972年由Telerman首次命名为本瘤，并沿用至今，本瘤病因尚不明了。发生年龄自新生儿到67岁妇女均可发生，少数为男性。临床表现：患者为正常女性及男性外表，女性病人可有下腹包块，发生蒂扭转时有下腹痛，并有急腹症症状，可有内分泌紊乱，性早熟表现，男性有睾丸增大。染色体核型分析均正常。内分泌检查与临床表现符合，肿瘤为单侧，圆形或卵圆形。表面光滑，直径2.5～30cm，实性肿瘤内有囊性区。切面灰白、灰红或淡黄至淡褐色。镜下有梭形细胞及生殖细胞。治疗：视情况采取单纯手术，或手术加放疗及化疗。需长期随访。预后：单纯本病者良好。
