非独立同分布 Non-IID与独立同分布IID - 简书
2024年1月4日 · IID指:输入空间X的所有样本服从一个隐含未知的分布,训练数据所有样本都是独立地从这个分布上采样而得。 在概率论与统计学中,独立同分布是指一组随机变量中每个变量的概率分布都相同,且这些随机变量互相独立。 一组随机变量独立同分布并不意味着它们的样本空间中每个事件发生概率都相同。 例如,投掷非均匀骰子得到的结果序列是独立同分布的,但掷出每个面朝上的概率并不相同。 所有的事物都是具有一定结构的系统,而我们常听说的“研究”,都以构 …
Independent and identically distributed random variables
In probability theory and statistics, a collection of random variables is independent and identically distributed (i.i.d., iid, or IID) if each random variable has the same probability distribution as the others and all are mutually independent. [1]
Irinotecan-mediated diarrhea is mainly correlated with intestinal ...
2020年7月1日 · Background and purpose: Irinotecan-induced diarrhea (IID) results from intestinal damages by its active metabolite SN-38. Alleviation of these damages has focused on lowering luminal SN-38 concentrations. However, it is unclear if the enteric bioavailability of SN-38 is mostly dependent on luminal SN-38 concentrations.
