摘要:

细胞系间的巨大变异性带来了癌症治疗药物选择的困难优化问题。标准方法为此目的使用预测值,例如对应于其分布的预期值。这篇文章显示了工作的优越性,预测整个概率分布-为此目的提出了基本工具。我们最感兴趣的是要测试的批次中最好的药物-对极端统计的选择进行适当的优化需要了解整个概率分布,对于细胞系中药物特性的分布,通常会出现二项式,例如,取决于相应的基因。因此,对于基本的预测机制,提出了两个高斯的混合,试图根据额外的信息来预测其权重。

英文摘要:

Large variability between cell lines brings a difficult optimization problem of drug selection for cancer therapy. Standard approaches use prediction of value for this purpose, corresponding e.g. to expected value of their distribution. This article shows superiority of working on, predicting the entire probability distributions - proposing basic tools for this purpose. We are mostly interested in the best drug in their batch to be tested - proper optimization of their selection for extreme statistics requires knowledge of the entire probability distributions, which for distributions of drug properties among cell lines often turn out binomial, e.g. depending on corresponding gene. Hence for basic prediction mechanism there is proposed mixture of two Gaussians, trying to predict its weight based on additional information.
