The purpose of normalization is to assist service users to see that their problems and situations are not unique. Many people in the society also have same experience. It can help the service user not to blame themselves as the defects of the social order. We can give some factual ...
C. Standardize the data for better comparison. D. Reduce the size of the dataset. 相关知识点: 试题来源: 解析 C。数据标准化的主要目的是使数据具有可比性。不是为了让数据好看。确保值在 0 和 1 之间只是一种特定的标准化方法。也不是为了减小数据集的大小。
The aim of this research was to evaluate the stability of seven potential reference genes (Actb, GAPDH, 18S rRNA, CycA, Hprt1, Ywhaz, and Pgk1) and select the most stable genes or a combination of stable genes for the purpose of normalization in IVD gene expression studying of rat and ...

The primary purpose of normalization is to deduce the training time and increase the system performance. It provides the ability to configure each layer separately with minimum dependency on each other. 3. Activation Function The activation function is a kind of barrier which doesn’t pass any par...

Before we examined the effect of gossypol on gene expression in human colon cancer cells, we evaluated the relative expression levels of 55 genes and selected the internal reference for qPCR analysis since it is important for normalization of gene expression levels80,81,82,83. Our study showed ...
It was natural to spend a lot of effort in elaborating a model based on relations and normalization rules. Any data stored in a relational database was then extracted and moved around using memory structures similar to an in-memory database. Record Set is the name of this generic data ...
The interface defines a normalizeAttribute method for this purpose. This method takes an ObjectClass and an Attribute to be normalized as arguments and returns the normalized Attribute. Attribute normalization is applied during many operations including: Filters that are passed to SearchOp Results retur...
Thus, the normalization of P ^ ( f ) yields a probability density function. Using the definition of Shannon entropy, SpEn can be defined as: S p E n = ∑ i = f l f h p i · l o g p i (9) where [ f l , f h ] is the frequency band. Spectral entropy is usually ...
