| 1 | 简化的Slope One在线评分预测算法显示文摘个性化推荐系统是大数据时代信息过滤的有效手段,影响推荐系统预测准确性的主要原因之一是数据稀疏性。Slope One评分预测推荐算法采用简单的线性回归模型解决数据稀疏问题,具有易于实现、评分预测速度快的特点,但它在训练阶段生成项目之间评分差的时间和空间消耗大,训练阶段需离线进行。为解决以上问题,提出一种简化的Slope One算法——Simplified Slope One,以两项目历史平均分之差代替项目评分差,来降低算法的时间复杂度和空间复杂度,简化耗时最多的生成项目之间评分差的过程,以有效提高评分数据的利用率,对稀疏数据有更好的适应性。在Movielens数据集上利用按照时间戳排序后划分的测试集进行实验,结果表明Simplified Slope One算法对评分预测的准确性与原Slope One算法接近,但时间复杂度和空间复杂度均低于原Slope One算法,更适合在数据规模增长迅速的大型推荐系统中应用。 | 孙丽梅 李悦 Ejike Ifeanyi Michael 曹科研 | 2018 | 计算机应用2018，38，2： | 3 |

| 14 | Evaluation of the acute and sub acute toxicity of Annona senegalensis root bark extracts显示文摘Objective:To investigate the safety profile of Annona senegalensis(A.senegalensis).Methods: Dried powdered root-bark of A.senegalensis was prepared by Sohxlet extraction using methanolmethylene chloride(1:1) solution and concentrated to obtain the methanol-methylene chloride extract(MME).MME was fractionated to obtain the n-hexane(HF),ethylacetate(EF) and methanol(MF) fractions.Acute toxicity(LD50) test was performed with MME,HF,EF and MF in mice by oral route.The sub acute toxicity studies were performed in rats after 14 days of MME administration while haemalological and biochemical parameters were monitored.Results: Medium lethal(LD-(50)) values of 1 296.3 808.1 265 and 2 154 mg/kg were obtained for the MME.MF, HF and EF,respectively.The sub-acute toxicity studies indicated a significant(P<0.05) increase in the body weight of both the treated rats and the control.The haematological tests indicated no change in the packed cell volume values but a significant(P<0.05) increase in the total WBC count at 100 and 400 mg/kg doses.The differential analysis showed a decrease in the nutrophils and a non-significant increase in the lymphocyte counts.The liver transaminase enzymes, alanin transaminase and aspartate transaminase showed no significant increase compared to the control.Histopathological examination of the liver sections also indicted no obvious signs of hepatotoxicity except with the 400 mg/kg dose that showed degeneration and necrosis of the hepatocytes.Conclusions:These results indicated that the root bark extracts of A.Senegalensis are safe at the lower doses tested,and calls for caution in use at higher doses in treatment. | Theophine C Okoye Peter A Akah Adaobi C Ezike Maureen O Okoye Collins A Onyeto Frankline Ndukwu Ejike Ohaegbulam Lovelyn Ikele | 2012 | Asian Pacific Journal of Tropical Medicine2012，5，4： | 1 |
